Abstract
Description
Technical Field
[0001] The invention relates to the field of machining equipment, and in particular to a machining center. Background Art
[0002] Traditional machining centers generally use a single spindle method, and the same single spindle machining center can only process one workpiece at a time. In specific work, after a workpiece is processed, the equipment needs to be shut down, and then the workpiece is disassembled and the workpiece to be processed is installed before the workpiece can be processed again; this causes a long downtime for the equipment to wait for clamping, and low equipment utilization and processing efficiency.
[0003] Furthermore, in order to improve the shortcomings of the traditional single-spindle machining center, some inventors have improved the traditional single-spindle machining center, changing the single spindle to a dual spindle, so that the machining center can process two workpieces at the same time; but the drive systems of the two spindles of the current dual-spindle machining center are independent of each other, and each spindle corresponds to an independent drive system, which drives the corresponding spindle to move in the X, Y, and Z axis directions through their own independent drive systems. In this way, not only the overall volume of the equipment is greatly increased, the space occupied by the equipment is greatly increased; but also the production cost is greatly increased. On the other hand, when the dual-spindle machining center is working, after the two workpieces are processed at the same time, the equipment needs to be shut down, and then the workpieces are disassembled and the workpieces to be processed are installed, and then the workpieces can be processed again. Therefore, there is also a problem of long equipment shutdown time for clamping, low equipment utilization and processing efficiency. In addition, since the operator disassembles and assembles the workpiece when the equipment is shut down, this requires the operator to quickly disassemble and assemble the workpiece, forcing the operator to be in a tense working state and increasing labor intensity. Summary of the invention
[0004] The first purpose of the present invention is to provide a machining center which can not only process two workpieces at the same time to improve machining efficiency, but also has a compact structure and can effectively reduce the manufacturing cost and occupied space of the machining center.
[0005] The second object of the present invention is to provide a machining center that can effectively shorten equipment downtime, thereby improving equipment utilization and machining efficiency, and is conducive to reducing the labor intensity of operators.
[0006] The technical solution of the present invention is: A machining center, comprising: A frame, wherein a longitudinal guide rail is provided on the frame; The longitudinal moving device comprises a longitudinal moving component sliding along the longitudinal guide rail and a longitudinal moving driving mechanism driving the longitudinal moving component to move, wherein the longitudinal moving component is provided with a transverse guide rail perpendicular to the longitudinal guide rail; Two transverse slides are slidably arranged on the transverse guide rails, each transverse slide is provided with a spindle box that slides in the vertical direction, and each transverse slide is provided with a lifting drive mechanism that drives the spindle box to rise and fall; The transverse driving mechanism is arranged on the longitudinal moving component, and each transverse slide is driven to slide by the transverse driving mechanism. The machining center of this scheme has two transverse slides, and each transverse slide is provided with a spindle box that slides in the vertical direction, so that two workpieces can be processed simultaneously by the spindle boxes on the two transverse slides to improve the machining efficiency. On the other hand, since the two transverse slides are arranged on the transverse guide rails on the same longitudinal moving component and driven by the same longitudinal driving mechanism, the spindle boxes on the two transverse slides can share a longitudinal moving device, thereby effectively improving the overall structural compactness of the machining center, effectively reducing the space occupied by the machining center, and at the same time, reducing the manufacturing cost.
[0007] As a preference, it also includes a workbench rotatably arranged on the frame and a rotary drive mechanism for driving the workbench to rotate, wherein the workbench is provided with two workstations, each workstation can be equipped with multiple workpieces at the same time, and the spindle boxes on the two transverse slides can process two workpieces on the same workstation at the same time. Based on this, when the spindle boxes on the two transverse slides process the workpiece on one of the workstations, the operator can disassemble the processed workpiece and install a new workpiece to be processed on the other workstation; and when the workpiece on one of the workstations is processed, the operator can drive the workbench to rotate 180 degrees through the rotary drive mechanism, and rotate the workpiece on the other workstation to the machining position for processing, without waiting for the operator to disassemble and install the workpiece, thereby effectively shortening the equipment downtime, thereby improving the equipment utilization rate and processing efficiency. On the other hand, since the operator disassembles and installs the workpiece during the process of processing the workpiece in the machining center, there is sufficient time to actually disassemble and install the workpiece, so that the operator is in a relaxed working state, thereby reducing the labor intensity of the operator.
[0008] Preferably, a partition is provided on the workbench to separate the two workstations on the workbench. In this way, when the spindle boxes on the two transverse slides process the two workpieces on one of the workstations, the partition can be used to block the high-speed rotating tool and the splashing debris generated by the machining, thereby avoiding the safety hazard of the operator accidentally touching the high-speed rotating tool and being scratched by the splashing debris when operating at the other workstation, thereby improving the safety of the operator in the removal and installation of the workpiece at the other workstation.
[0009] Preferably, an upper baffle is provided on the top of the partition, a part of the upper baffle extends toward one of the working positions to form a working position blocking portion, and another part of the upper baffle extends toward another working position to form a working position blocking portion; a mounting plate is provided at the bottom of the partition, and the mounting plate is connected to the workbench by bolts, welding or riveting. In this way, on the one hand, the partition can be installed by the mounting plate, which is convenient for the installation of the partition; on the other hand, the blocking portion on the top of the partition can further improve the blocking effect of splashing debris.
[0010] Preferably, the upper surface of the workbench where each workstation is located is provided with a workpiece mounting groove or a workpiece mounting hole, and the workpiece mounting groove is a T-slot or a dovetail groove. In this way, the workpiece can be mounted on the tooling during actual use; then, the tooling is mounted in the workpiece mounting groove (a T-block or dovetail block matching the T-slot or dovetail groove is provided at the bottom of the tooling) to facilitate the installation of the tooling and the workpiece; or the tooling is directly mounted on the workpiece mounting hole by bolts, or the workpiece is directly mounted on the workpiece mounting hole by bolts.
[0011] Preferably, it also includes an anti-collision locking device, the workbench includes a cylindrical section, and two symmetrically distributed arc grooves are provided on the outer side of the cylindrical section; The anti-collision locking device includes: A top rod and a locking rod slidably arranged on the frame; A locking hole is provided on the longitudinal moving component; A push rod spring and a locking rod spring, one end of the push rod is pressed against the outer surface of the cylindrical section under the action of the push rod spring; A connecting rope connects the top rod and the locking rod, and the connecting rope passes around a guide member arranged on the frame; When the longitudinal moving component is in the initial position and one end of the push rod is against the outer surface of the cylindrical section, the locking rod extends into the locking hole under the action of the locking rod spring; When the longitudinal moving part is in the initial position and the workbench rotates to align the arc groove with the push rod, the push rod spring overcomes the force of the lock rod spring, so that one end of the push rod extends into the arc groove and the lock rod is separated from the locking hole. The use of a workbench can effectively shorten the equipment downtime, thereby improving equipment utilization and processing efficiency; but at the same time, in the actual operation process, it is also necessary for operators to install and operate in accordance with the specifications. Specifically, When the machining center completes the processing of two workpieces on a workstation, the spindle box is reset (the lifting drive mechanism drives the spindle box to move up and reset, the transverse drive mechanism resets the transverse slide, and the longitudinal drive mechanism drives the longitudinal component to move backward and reset). Then, the operator controls the worktable to rotate 180 degrees before controlling the spindle box of the machining center to move to the workstation to process the workpiece. However, in the actual operation process, due to the negligence of the operator or the failure to install and operate in a hurry, the longitudinal component is mistakenly controlled to move to the workstation during the rotation of the worktable, resulting in a collision between the workpiece on the worktable and the tool, causing damage to the workpiece or the tool. In order to solve this problem, this solution provides an anti-collision locking device. Specifically, After the machining center completes the machining of two workpieces on a workstation and the spindle box is reset to the initial position, when the operator controls the worktable to rotate, the push rod will quickly move out of the arc groove, so that one end of the push rod will rest against the outer surface of the cylindrical section. At this time, the locking rod will extend into the locking hole under the action of the locking rod spring, thereby locking the longitudinal movement component to avoid the problem of erroneous control of the longitudinal movement component to move to the workstation during the rotation of the workstation, which may cause the workpiece on the workstation to collide with the tool and cause damage to the workpiece or the tool; when the worktable rotates 180 degrees, the arc groove will be aligned with the push rod. At this time, the push rod spring overcomes the force of the locking rod spring, so that one end of the push rod extends into the arc groove, and at the same time, the locking rod is driven to move and separate from the locking hole through the connecting rope, thereby releasing the lock of the longitudinal movement component; therefore, when the worktable rotates 180 degrees, the spindle box of the machining center can be smoothly controlled to move to the workstation to process the workpiece, without affecting the normal operation of the machining center.
[0012] As a preferred embodiment, two tool magazines are further included, which are distributed on both sides of the frame along the transverse guide rails, and two transverse slides are located between the two tool magazines. In this way, automatic tool change can be achieved through the tool magazines to perform different machining processes such as boring, milling, drilling, and tapping.
[0013] As a preferred embodiment, a tool magazine is also included, and the tool magazine is located between the two transverse slides. In this way, automatic tool change can be achieved through the tool magazine to perform different machining processes such as boring, milling, drilling, and tapping.
[0014] Preferably, the frame includes a base and two side frames on the base, the tops of the two side frames are respectively provided with the longitudinal guide rails, and the longitudinal moving component is supported on the longitudinal guide rails on the tops of the two side frames. In this way, the stability of the frame itself and the smooth movement of the longitudinal moving component can be ensured.
[0015] Preferably, the longitudinal guide rails extend along the front-to-back direction of the frame, and the transverse guide rails include two parallel upper and lower transverse guide rails, the upper transverse guide rail is higher than the lower transverse guide rail, and in the longitudinal guide rail direction, the lower transverse guide rail is located in front of the upper transverse guide rail. Since the upper and lower transverse guide rails of the transverse guide rails adopt a stepped step distribution with the front lower and the rear higher (in the longitudinal guide rail direction, the lower transverse guide rail is located in front of the upper transverse guide rail), this is conducive to improving the moving stability of the transverse slide.
[0016] Preferably, a vertical groove is provided on the transverse slide, and the vertical groove extends in the up-down direction and passes through the upper and lower ends of the transverse slide, and the notch of the vertical groove faces the spindle box. Since the vertical groove extends in the up-down direction and passes through the upper and lower ends of the transverse slide, and the notch of the vertical groove faces the spindle box, the lifting drive mechanism is arranged in the vertical groove. In this way, on the one hand, the lifting drive mechanism and the protruding part of the spindle box facing the side of the transverse slide can be accommodated by the vertical groove, thereby improving the compactness of the structure; on the other hand, part of the heat generated during the high-speed operation of the spindle box can be discharged through the vertical groove, which is beneficial to the heat dissipation of the spindle box.
[0017] The beneficial effects of the present invention are: Firstly, it can not only process two workpieces at the same time to improve processing efficiency, but also has a compact structure, which can effectively reduce the production cost and occupied space of the machining center.
[0018] Secondly, it can effectively shorten equipment downtime, thereby improving equipment utilization and processing efficiency, and helping to reduce the labor intensity of operators. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Specific embodiment 1, as Figure 1 , Figure 2 , Figure 3 As shown, a machining center comprises a frame 1, a longitudinal movement device, two transverse movement slides 4 and a transverse movement driving mechanism. The frame 1 is provided with a longitudinal guide rail 1.3.
[0025] The longitudinal moving device includes a longitudinal moving component 2 sliding along the longitudinal guide rail 1.3 and a longitudinal moving driving mechanism driving the longitudinal moving component 2 to move. The longitudinal moving driving mechanism is arranged on the frame 1. In this embodiment, the longitudinal moving driving mechanism is an electric cylinder or a linear module. The longitudinal moving component 2 is provided with a transverse guide rail 3 perpendicular to the longitudinal guide rail 1.3. The longitudinal guide rail 1.3 and the transverse guide rail 3 are both horizontally distributed.
[0026] The two transverse slides 4 are both slidably arranged on the transverse guide rail 3. The two transverse slides 4 are distributed in sequence along the transverse guide rail 3.
[0027] The transverse driving mechanism is arranged on the longitudinal moving component 2. Each transverse moving slide 4 is driven to slide by the transverse driving mechanism. In this embodiment, the transverse driving mechanism is an electric cylinder or a linear module.
[0028] Each traverse slide 4 is provided with a spindle box 5 that slides in the vertical direction. Specifically, the spindle box 5 is slidably arranged on the traverse slide 4 through a vertical guide rail 7. Each traverse slide is provided with a lifting drive mechanism that drives the spindle box to rise and fall. In this embodiment, the lifting drive mechanism is an electric cylinder or a linear module.
[0029] The machining center of this embodiment has two transverse slides 4, each of which is provided with a spindle box 5 that slides in the vertical direction, so that two workpieces can be processed simultaneously by the spindle boxes 5 on the two transverse slides 4, so as to improve the machining efficiency. On the other hand, since the two transverse slides 4 are both arranged on the transverse guide rails 3 on the same longitudinal moving component 2 and driven by the same longitudinal moving driving mechanism, the spindle boxes 5 on the two transverse slides 4 can share a longitudinal moving device, thereby effectively improving the overall structural compactness of the machining center, effectively reducing the space occupied by the machining center, and at the same time reducing the manufacturing cost.
[0030] Specific embodiment 2, as Figure 1 , Figure 2 , Figure 3 As shown, a machining center comprises a frame 1, a longitudinal movement device, two transverse movement slides 4, a transverse movement drive mechanism, a workbench 6 and a rotation drive mechanism. The frame 1 is provided with a longitudinal guide rail 1.3.
[0031] The longitudinal moving device includes a longitudinal moving component 2 sliding along the longitudinal guide rail 1.3 and a longitudinal moving driving mechanism driving the longitudinal moving component 2 to move. The longitudinal moving driving mechanism is arranged on the frame 1. In this embodiment, the longitudinal moving driving mechanism is an electric cylinder or a linear module. The longitudinal moving component 2 is provided with a transverse guide rail 3 perpendicular to the longitudinal guide rail 1.3. The longitudinal guide rail 1.3 and the transverse guide rail 3 are both horizontally distributed.
[0032] Both transverse slides 4 are slidably arranged on the same transverse guide rail 3. The two transverse slides 4 are sequentially distributed along the transverse guide rail 3. The transverse driving mechanism is arranged on the longitudinal moving component 2. Each transverse slide 4 is driven to slide by the transverse driving mechanism. In this embodiment, the transverse driving mechanism corresponds to the transverse slide 4 one by one, and the transverse driving mechanism drives the corresponding transverse slide 4 to slide along the transverse guide rail 3. In this embodiment, the transverse driving mechanism is an electric cylinder or a linear module.
[0033] Each transverse slide 4 is provided with a spindle box 5 that slides in the vertical direction. Specifically, the spindle box 5 is slidably set on the transverse slide 4 through a vertical guide rail 7. In the present embodiment, there are two spindle boxes 5, and the spindle boxes 5 correspond to the transverse slides 4 one by one. The spindle of the spindle box 5 is distributed vertically. Of course, it should be noted that the spindle of the spindle box 5 is not limited to the vertical distribution, but can also be distributed horizontally. Each transverse slide is provided with a lifting drive mechanism for driving the spindle box to rise and fall. In the present embodiment, the lifting drive mechanism is an electric cylinder or a linear module.
[0034] The workbench 6 is rotatably arranged on the frame 1. The rotary drive mechanism drives the workbench 6 to rotate. The rotation axis of the workbench 6 is vertically distributed. In the present embodiment, the rotary drive mechanism includes a drive motor. Two workstations 6.1 are arranged on the workbench 6. Each workstation 6.1 can be equipped with multiple workpieces at the same time, and the spindle boxes 5 on the two transverse slides 4 can process two workpieces on the same workstation 6.1 at the same time. Since the machining center has two spindle boxes, during the actual machining process, the number of workpieces installed at each workstation 6.1 at the same time is generally an even number, for example, 2 or 4 or 6 workpieces are installed at each workstation 6.1 at the same time. Of course, it should be noted that the number of workpieces installed at each workstation 6.1 at the same time can also be an odd number, for example, 1 or 3 or 5 workpieces are installed at each workstation 6.1 at the same time.
[0035] During specific operation, the longitudinal moving component 2 is driven to move along the longitudinal guide rail 1.3 by the same longitudinal moving driving mechanism, thereby driving the two transverse moving slides 4 and the spindle box 5 on the transverse moving slide 4 to move synchronously along the longitudinal guide rail 1.3; the corresponding transverse moving slide 4 is driven to slide along the transverse guide rail 3 by the transverse moving driving mechanism, thereby driving the two transverse moving slides 4 and the spindle box 5 on the transverse moving slide 4 to move independently along the transverse guide rail 3; the corresponding spindle box 5 is driven to rise and fall by the lifting driving mechanism. Since the two transverse moving slides 4 are both arranged on the transverse guide rail 3 on the same longitudinal moving component 2 and driven by the same longitudinal moving driving mechanism, the spindle boxes 5 on the two transverse moving slides 4 can share a longitudinal moving device, thereby effectively improving the overall structural compactness of the machining center, effectively reducing the space occupied by the machining center, and at the same time reducing the manufacturing cost.
[0036] The machining center of this embodiment has two transverse slides 4, and each transverse slide 4 is provided with a spindle box 5 sliding in the vertical direction. Therefore, two workpieces on the same work station 6.1 can be processed simultaneously by the spindle boxes 5 on the two transverse slides 4 to improve the processing efficiency.
[0037] At the same time, in the actual operation process, when the spindle boxes 5 on the two transverse slides 4 are processing the two workpieces on one of the workstations 6.1, the operator can disassemble the processed workpieces and install new workpieces to be processed on the other workstation 6.1; and when the two workpieces on one of the workstations 6.1 are processed, the operator can drive the worktable 6 to rotate 180 degrees through the rotary drive mechanism, and rotate the workpiece on the other workstation 6.1 to the machining position for processing, without waiting for the operator to disassemble and install the workpiece, thereby effectively shortening the equipment downtime, thereby improving equipment utilization and processing efficiency. In addition, since the operator disassembles and installs the workpiece during the process of processing the workpiece in the machining center, there is sufficient time to actually disassemble and install the workpiece, so that the operator is in a relaxed working state, thereby reducing the labor intensity of the operator.
[0038] Specifically, Figure 1 , Figure 2 , Figure 3 As shown, the frame 1 includes a base 1.1 and two left and right side frames 1.2 arranged on the base 1.1. The base 1.1 and the two left and right side frames 1.2 are an integrally formed structure; or the base and the side frames are made separately, and then the base and the side frames are connected by bolts or welding. The tops of the two side frames 1.2 are respectively provided with the aforementioned longitudinal guide rails 1.3. The longitudinal moving component 2 is supported on the longitudinal guide rails 1.3 on the tops of the two side frames 1.2. In this way, the stability of the frame 1 itself and the smooth movement of the longitudinal moving component 2 can be ensured. In this embodiment, the longitudinal moving component 2 is composed of a crossbeam, and the crossbeam is parallel to the transverse guide rail 3.
[0039] The workbench 6 is rotatably arranged on the base 1.1 of the frame 1. The rotation driving mechanism is also arranged on the base 1.1 of the frame 1.
[0040] In this embodiment, the longitudinal guide rail 1.3 extends and distributes along the front-to-back direction of the frame 1. The transverse guide rail 3 extends and distributes along the left-to-right direction of the frame 1.
[0041] In this embodiment, the machining center further includes a tool magazine 8. Specifically, In one embodiment, Figure 1 , Figure 2 As shown, there are two tool magazines 8, and the two tool magazines 8 are distributed on both sides of the frame 1 along the transverse guide rails 3. Two transverse slides 4 are located between the two tool magazines 8. Two spindle boxes 5 are also located between the two tool magazines 8. The spindle boxes 5 correspond to the tool magazines 8 one by one. The tools on the spindle boxes 5 are automatically changed through a corresponding tool magazine 8. In this way, the automatic tool change of the spindle box 5 can be realized through the tool magazine 8, and different machining processes such as boring, milling, drilling, and tapping can be performed.
[0042] In another embodiment, there is one tool magazine 8, which is located between two transverse slides 4 (not shown in the figure). Specifically, the tool magazine 8 is arranged between the left and right side frames 1.2. The tool magazine 8 can automatically change tools for the two spindle boxes 5, that is, the two spindle boxes 5 share one tool magazine 8. In this way, the tool magazine 8 can realize automatic tool change of the spindle box 5, and perform different machining processes such as boring, milling, drilling, and tapping.
[0043] Further, such as Figure 1 , Figure 2 As shown, the transverse guide rail 3 includes two parallel transverse guide rails, the upper transverse guide rail 3.1 being higher than the lower transverse guide rail 3.2.
[0044] In one example, in the direction of the longitudinal track 1.3, the lower transverse guide rail 3.2 is located in front of the upper transverse guide rail 3.1. The cross section of the transverse slide 4 increases first and then decreases from bottom to top. Since the upper and lower transverse guide rails of the transverse track 3 are distributed in a stepped manner with the front lower and the rear higher (in the direction of the longitudinal track 1.3, the lower transverse guide rail is located in front of the upper transverse guide rail), this is conducive to improving the moving stability of the transverse slide 4.
[0045] In another example, the projections of the lower transverse guide rail 3.2 and the upper transverse guide rail 3.1 in the vertical direction coincide with each other.
[0046] Further, such as Figure 1 As shown, a vertical groove 4.1 is provided on the transverse slide 4, and the vertical groove 4.1 extends in the up-down direction and passes through the upper and lower ends of the transverse slide 4. The vertical guide rail 7 includes two parallel vertical guide rails, and the two vertical guide rails are distributed on both sides of the notch of the vertical groove 4.1. The notch of the vertical groove 4.1 faces the spindle box 5. In this embodiment, the lifting drive mechanism is arranged in the vertical groove. Since the vertical groove 4.1 extends in the up-down direction and passes through the upper and lower ends of the transverse slide 4, and the notch of the vertical groove 4.1 faces the spindle box 5, on the one hand, the vertical groove 4.1 can be used to accommodate the lifting drive mechanism and the protruding part of the spindle box 5 facing the slide side of the transverse slide 4, thereby improving the compactness of the structure; on the other hand, part of the heat generated during the high-speed operation of the spindle box 5 can be discharged through the vertical groove 4.1, which is beneficial to the heat dissipation of the spindle box 5. Of course, the lifting drive mechanism can also be arranged at other positions of the transverse slide.
[0047] Further, such as Figure 1 , Figure 3 As shown, a partition 6.0 is provided on the workbench 6, and the partition 6.0 separates two workstations 6.1 on the workbench 6. In this way, when the spindle boxes 5 on the two transverse slides 4 process two workpieces on one of the workstations 6.1, the partition 6.0 can be used to block the high-speed rotating tool and the splashing debris generated by the machining, thereby avoiding the safety hazard of the operator accidentally touching the high-speed rotating tool and being scratched by the splashing debris when operating on the other workstation 6.1, thereby improving the safety of the operator in the removal and installation operations of the workpiece on the other workstation 6.1.
[0048] Further, such as Figure 1 , Figure 3As shown, an upper baffle 6.3 is provided on the top of the partition 6.0, a part of the upper baffle 6.3 extends toward one of the working positions 6.1 to form a blocking portion of the working position 6.1, and another part of the upper baffle 6.3 extends toward another working position 6.1 to form a blocking portion of the working position 6.1. In this way, the blocking portion on the top of the partition 6.0 can further improve the blocking effect of flying debris. In this embodiment, the side of the partition 6.0 is vertically distributed. The upper baffle 6.3 is perpendicular to the partition 6.0.
[0049] The bottom of the partition 6.0 is provided with a mounting plate, which is connected to the workbench 6 by bolts, welding or riveting. In this way, the partition 6.0 can be installed by the mounting plate, which is conducive to the installation of the partition 6.0.
[0050] Further, such as Figure 1 , Figure 3 As shown, the upper surface of the workbench where each workstation is located is provided with a workpiece mounting groove or a workpiece mounting hole. Specifically, In one example, the upper surface of the workbench 6 where each work station 6.1 is located is provided with a workpiece mounting groove 6.2, and the workpiece mounting groove 6.2 is a T-shaped groove or a dovetail groove. In this way, the workpiece can be mounted on the tooling during actual use, and a T-shaped block or a dovetail block matching the T-shaped groove or the dovetail groove is provided at the bottom of the tooling, so that the tooling can be conveniently mounted on the workpiece mounting groove 6.2, thereby facilitating the installation of the workpiece.
[0051] In another example, the upper surface of the workbench where each workstation is located is provided with a workpiece mounting hole. In this way, the workpiece can be mounted on the tooling during actual use, and the tooling is mounted on the workpiece mounting hole by bolts, thereby facilitating the installation of the workpiece.
[0052] Of course, it should be noted that in actual production, the tooling for clamping the workpiece can also be fixed by means of positioning pin holes or positioning grooves.
[0053] Specific embodiment 3: The rest of the structure of this embodiment refers to specific embodiment 2, except that: like Figure 4 As shown, the machining center also includes an anti-collision locking device. The workbench 6 includes a cylindrical section 6.4, and the cylindrical section 6.4 is located below the table surface of the workbench 6. The cylindrical section 6.4 is coaxial with the rotating axis of the workbench 6. The outer side surface of the cylindrical section 6.4 is a cylindrical surface. Two arc grooves 6.5 symmetrically distributed around the rotating axis of the workbench 6 are provided on the outer side surface of the cylindrical section 6.4, and the inner wall surface of the arc groove 6.5 is an arc surface, and the two ends of the arc surface are smoothly transitionally connected to the outer side surface of the cylindrical section 6.4.
[0054] The anti-collision locking device includes a push rod 9.1, a locking rod 9.5, a locking hole 9.6, a push rod spring 9.2, a locking rod spring 9.7 and a connecting rope 9.10. The push rod 9.1 is slidably set on the frame 1. In this embodiment, the push rod 9.1 is slidably set on the bottom frame. The push rod 9.1 extends radially along the cylindrical section 6.4. One end of the push rod 9.1 is against the outer surface of the cylindrical section 6.4 under the action of the push rod spring 9.2. The locking rod 9.5 is slidably set on the frame 1. In this embodiment, the locking rod 9.5 is slidably set on the side frame 1.2; the locking rod 9.5 is vertically distributed, and the locking rod 9.5 is located below the longitudinal moving component 2; the locking rod spring 9.7 drives the locking rod 9.5 to move upward; the locking hole 9.6 is set on the longitudinal moving component 2, and the opening of the locking hole 9.6 faces downward. The elastic force of the push rod spring 9.2 is greater than the elastic force of the locking rod spring 9.7. Of course, the locking rods 9.5 can also be distributed horizontally or obliquely. At the same time, the positions of the locking holes 9.6 are adjusted accordingly according to the distribution state of the locking rods 9.5.
[0055] The connecting rope 9.10 connects the top rod 9.1 and the locking rod 9.5. The connecting rope 9.10 passes around the guide member 9.11 arranged on the frame 1.

Herein, the longitudinal moving part 2 being in the initial position refers to the position when the longitudinal moving drive mechanism drives the longitudinal moving part 2 to move backward along the longitudinal guide rail 1.3 to be in place. In this embodiment, a limit block is provided at the rear of the longitudinal guide rail 1.3, and the limit block is located at the rear side of the longitudinal moving part 2. When the longitudinal moving part 2 moves backward along the longitudinal guide rail 1.3 and abuts against the limit block, the longitudinal moving part 2 is in the initial position.
[0057] When the longitudinal displacement member 2 is in the initial position and one end of the push rod 9.1 abuts against the outer side of the cylindrical section 6.4, the locking rod 9.5 extends into the locking hole 9.6 under the action of the locking rod spring 9.7.
[0058] When the longitudinal moving part 2 is in the initial position and the workbench 6 rotates to align the arc groove 6.5 with the push rod 9.1, the push rod spring 9.2 overcomes the force of the lock rod spring 9.7, so that one end of the push rod 9.1 extends into the arc groove 6.5 and abuts against the inner wall surface of the arc groove, and the lock rod 9.5 is separated from the locking hole 9.6.
[0059] In this embodiment, the anti-collision locking device also includes a push rod guide sleeve 9.3 and a lock rod guide sleeve 9.8 fixedly arranged on the frame 1, the push rod 9.1 is slidably arranged in the push rod guide sleeve 9.3, and a push rod stopper 9.4 is arranged on the push rod 9.1, and the push rod stopper 9.4 is located between the cylindrical section 6.4 and the push rod guide sleeve 9.3. The push rod spring 9.2 is sleeved on the push rod 9.1 and is located between the push rod stopper 9.4 and the push rod guide sleeve 9.3.

[0061] The use of the workbench 6 can effectively shorten the equipment downtime, thereby improving equipment utilization and processing efficiency; but at the same time, in the actual operation process, it is also necessary for the operator to install and operate in accordance with the specifications. Specifically, when the machining center completes the processing of two workpieces on a work position 6.1, the spindle box 5 is reset (the lifting drive mechanism drives the spindle box 5 to move up and reset, the transverse drive mechanism transverse slide 4 is reset, and the longitudinal drive mechanism drives the longitudinal component 2 to move backward and reset). Then, the operator controls the workbench 6 to rotate 180 degrees before controlling the spindle box 5 of the machining center to move to the work position 6.1 to process the workpiece; however, in the actual operation process, due to the operator's negligence or failure to install and operate in accordance with the specifications in a rush, the workbench 6 may mistakenly control the longitudinal component 2 to move to the work position 6.1 during rotation, resulting in a collision between the workpiece on the workbench 6 and the tool, causing damage to the workpiece or the tool. In order to solve this problem, the present embodiment provides an anti-collision locking device. Specifically, When the operator controls the workbench 6 to rotate so that the arc groove 6.5 is aligned with the push rod 9.1, a work position 6.1 on the workbench 6 is in the machining position of the machining center. At this time, the spindle box 5 on the two transverse slides 4 of the machining center can process the two workpieces on the work position 6.1; at the same time, the push rod spring 9.2 overcomes the force of the lock rod spring 9.7, so that one end of the push rod 9.1 extends into the arc groove 6.5, and the lock rod 9.5 is separated from the locking hole 9.6; at this time, the movement of the longitudinal moving component 2 is not affected; Next, after the machining center completes machining of two workpieces on a work station 6.1, the driving mechanism (including the longitudinal, transverse and lifting driving mechanisms) drives the spindle box 5 to reset, so that the longitudinal moving component 2 is in the initial position. At this time, the longitudinal moving component 2 is against the limit block; Next, the operator controls the workbench 6 to rotate. During this process, the push rod 9.1 will quickly move out of the arc groove 6.5, and one end of the push rod 9.1 will abut against the outer surface of the cylindrical section 6.4; when one end of the push rod 9.1 abuts against the outer surface of the cylindrical section 6.4, the locking rod 9.5 will extend into the locking hole 9.6 under the action of the locking rod spring 9.7, thereby locking the longitudinal moving component 2 to prevent the longitudinal moving component 2 from being mistakenly controlled to move toward the working position 6.1 during the rotation of the workbench 6, resulting in a collision between the workpiece on the workbench 6 and the tool, causing the workpiece or the tool to be damaged. Damage problem; when the workbench 6 rotates 180 degrees, the arc groove 6.5 will be aligned with the push rod 9.1. At this time, the push rod spring 9.2 overcomes the force of the locking rod spring 9.7, so that one end of the push rod 9.1 extends into the arc groove 6.5, and at the same time, the locking rod 9.5 is driven to move downward and separate from the locking hole 9.6 through the connecting rope 9.10, thereby releasing the lock of the longitudinal movement component 2; therefore, when the workbench 6 rotates 180 degrees, the longitudinal movement component 2 of the machining center can be smoothly controlled to move to the working position 6.1 to process the workpiece, without affecting the normal operation of the machining center.
