Description

Technical Field

[0001] This invention relates to the field of CNC machining technology, and in particular to a receiving device suitable for CNC lathes and its usage method. Background Technology

[0002] The automated loading and unloading (feeding and receiving) of CNC lathes requires the use of a material conveying system.

[0003] In the existing technology, the feeding and receiving of CNC lathes are usually completed by two sets of material conveying systems: one set is used to convey the blank bar stock to be processed, and the other set is used to convey the processed workpiece. Both sets of material conveying systems require a certain amount of workshop space, and the space occupied is relatively large, which affects the number of CNC lathes that can be arranged in the limited workshop space (the arrangement of CNC machine tools in the workshop needs to consider not only the space volume occupied by the machine itself, but also the space occupied by its own material conveying system) and will also hinder the passage of internal roads in the workshop.

[0004] Material conveying systems used to transport finished workpieces need to prevent rolling and collision damage to the workpieces, which could affect product quality. Therefore, they require specially designed carriers (braces) on their conveying structures to adapt to the workpieces. In order for the carriers to adapt well to the finished workpieces and effectively restrict their movement to ensure the stability of the conveying, different carriers are generally designed and manufactured for different specifications of workpieces. This results in high overall costs and poor applicability. Changing the workpieces to be processed requires cumbersome and complex adjustments, and both manufacturing and maintenance costs are high.

[0005] Furthermore, in existing technologies, the material handling system of CNC lathes can generally only be adapted to a single CNC lathe, resulting in low utilization and high overall operating costs.

[0006] Therefore, there is a need for a receiving device suitable for CNC lathes that is highly adaptable, occupies relatively little space, operates stably and reliably, causes minimal damage to workpieces during transport, does not require changing workpiece carriers when changing workpieces, has relatively low manufacturing and usage costs, can transport over long distances, and can adapt one conveying system to multiple CNC lathes. Summary of the Invention

[0007] This application provides a receiving device suitable for CNC lathes, solving the technical problems of existing CNC lathe material conveying systems, such as large space occupation, poor applicability, the need to design different carriers for different workpieces, and relatively high manufacturing and usage costs. It achieves the technical advantages of a receiving device suitable for CNC lathes that is highly applicable, occupies relatively little space, operates stably and reliably, causes minimal damage to workpieces during transport, eliminates the need to change workpiece carriers when changing workpieces, has relatively low manufacturing and usage costs, enables long-distance transport, and allows one conveying system to be adapted to multiple CNC lathes.

[0008] This application provides a receiving device suitable for CNC lathes, used to transport and transfer blank bars and receive and transport workpieces processed from blank bars by CNC machine tools.

[0011] Furthermore, the side-pushing material loading assembly includes a side push rod positioned on one side of the basic conveying assembly and a material loading tray positioned on the other side of the basic conveying assembly, and is set close to the CNC lathe; The side push rod is a horizontal rigid telescopic rod, which is fixed to the ground by a rigid bracket. Its axis is perpendicular to the length direction of the basic conveying component. It is controlled to extend and retract. When it extends, it pushes one of the blank bars and pushes it to the top of the loading tray.

Its length direction is the same as the axial direction of the first rotating body and it is in direct contact with the inner ring of the bearing annular belt. The presence of the support assembly can reduce the bending of the bearing annular belt in the horizontal direction.

[0013] Preferably, it also includes a side-guiding component; The number of side guide components is two, which are positioned on the ground and located on both sides of the basic conveying component, close to the material receiving component; The side guide assembly includes a bottom rail, a vertical frame, support rollers, and an abutment belt; The bottom rail is a horizontally placed rigid guide rail, positioned on the ground, with its length direction being the same as the width direction of the basic conveying component.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, the material receiving device of this application is applicable to CNC lathes for conveying and transferring blank bar stock 001 and receiving and conveying workpiece 002 processed from blank bar stock 001 by CNC machine tool. One set of material receiving device is used for material feeding of multiple CNC lathes at the same time, including basic conveying component 100, material carrying base plate component 200, side pushing material carrying component, clamping and shifting component 500, power component and control unit.

[0026] The basic conveying assembly 100 includes a first rotating body 110, a second rotating body 120, three positioning conveying units 130, and a support frame 140; like Figure 4 and Figure 5 As shown, the first rotating body 110 and the second rotating body 120 are both horizontally placed rigid rollers. Both are positioned on the ground by the support frame 140 and rotate around their own axes. The distance between them is determined according to the length of the workshop and the number of CNC lathes that need to be adapted, and is at least 10 times their own axial length. At least one of them rotates under the coordinated control of the power component and the control unit. The support frame 140 is a rigid support. The positioning and conveying unit 130 serves a conveying function and is positioned on the first rotating body 110 and the second rotating body 120. The three positioning and conveying units 130 are set at the same height, are parallel to each other, and have an adjustable spacing. A positioning and conveying unit 130 includes two carrier belts and a supporting annular belt 133; the carrier belts are annular tubular, and the two carrier belts are respectively positioned on the first rotating body 110 and the second rotating body 120; the supporting annular belt 133 is an annular belt, sleeved on the two carrier belts and supported by the two carrier belts in a horizontally elongated oval shape, with a limiting positioning rod 134 positioned on the outer ring; when the first rotating body 110 and the second rotating body 120 rotate, they drive the supporting annular belt 133 to rotate and move; like Figure 7 and Figure 8 As shown, a straight groove is positioned on both the first rotating body 110 and the second rotating body 120. The length direction of the straight groove is the same as the axial direction of the first rotating body 110 and the second rotating body 120, which is used to guide the carrier body to slide. The carrier body includes an adjustable sliding tube 131 and a rotating sleeve 132. The adjustable sliding tube 131 is a rigid tube that is sleeved and slidably positioned on the first rotating body 110 and the second rotating body 120. The inner wall is provided with protrusions that can be embedded into the straight grooves of the first rotating body 110 and the second rotating body 120. The adjustable sliding tube 131 is detachably fixed to the first rotating body 110 as needed by the combination of bolts and bolt holes and the combination of pins and pin holes. The rotating sleeve 132 is a rigid tube that is sleeved on and detachably fixed to the adjustable sliding tube 131 and rotates around the axis of the adjustable sliding tube 131. The rotating sleeve 132 is detachably fixed to the adjustable sliding tube 131 as needed by the combination of bolts and bolt holes and the combination of pins and pin holes. When different workpieces 002 need to be processed, the basic conveying assembly 100 can be adapted to different workpieces 002 by adjusting the positioning position of the adjustable sliding tube 131 on the first rotating body 110 and the second rotating body 120 and the relative position of the rotating sleeve 132 and the adjustable sliding tube 131. A ring of teeth is positioned on the outer side wall of the rotating sleeve 132; the bearing annular belt 133 is a belt, and the inner ring is positioned with a tooth groove that matches the teeth on the outer side wall of the rotating sleeve 132. The limiting positioning rod 134 is a rigid rod with a length greater than 4 cm. It is a metal and / or non-metal rod. If it is a metal rod, it is fitted with a non-metallic outer sleeve. When the limiting positioning rod 134 is rotated to the vertical position, its axis is perpendicular to the overall length direction of the bearing ring belt 133. The distance between the limiting positioning rods 134 on the same bearing ring belt 133 is greater than 30 cm.

[0027] The material-carrying base plate assembly 200 is used to support the blank bar stock 001, including a material-carrying body 210, a material-feeding assembly with a material-dividing and blocking mechanism, and a support frame 240. The material-carrying body 210 is a horizontally placed rigid strip plate, with its length direction similar to that of the base conveying assembly 100. It is positioned on the ground and located at the bottom of the base conveying assembly 100. The blank bar stock 001 it carries is pushed by the limiting positioning rod 134 of the base conveying assembly 100 to roll and move to the target position as needed. The material-carrying body 210 has an angle of 1 to 3 degrees with the horizontal ground, and the end near the material-feeding assembly is lower. The material-feeding assembly is used to feed the blank bar stock 001 to the material-carrying body 210 in a timed and quantitative manner. It is positioned near one end of the material-carrying body 210 and is existing technology, controlled by the control unit. The support frame 240 is a rigid support that serves to support the material-carrying body 210 and the material-feeding assembly.

[0028] like Figure 1 and Figure 2 As shown, the side-pushing material loading assembly is used to push the blank bar 001 out from a suitable position of the loading base plate assembly 200 and expose it for subsequent movement to a CNC lathe for processing. Multiple assemblies are included, each corresponding to a CNC lathe with a receiving device applicable to the CNC lathe in this application. Each assembly includes a side push rod 310 positioned on one side of the base conveying assembly 100 and a loading tray 320 positioned on the other side of the base conveying assembly 100, located close to the CNC lathe. The side push rod 310 is a horizontally placed rigid telescopic rod, fixed to the ground by a rigid bracket, and its axial direction is parallel to the base conveying assembly 100. The length direction of 0 is perpendicular to the controllable extension and retraction. When it extends, it pushes one of the blank bars 001 and pushes it to the top of the material carrier plate 320. The material carrier plate 320 is a horizontally placed slide-shaped plate, which is fixed to the ground by a rigid bracket. The longitudinal section is an upward-opening "(" shape. Non-metallic rollers are positioned on the concave surface to reduce the sliding friction of the blank bars 001. One side push rod 310 corresponds to one or more material carrier plates 320. After the blank bars 001 are pushed out by the side push rod 310, they will move onto the material carrier plate 320 for clamping and displacement by the clamping and displacement assembly 500.

[0029] The clamping and shifting assembly 500 consists of multiple clamps (electric or pneumatic clamps) on a suspended guide rail or a robotic arm, controlled by a control unit. Each clamp corresponds to a CNC lathe for which the receiving device of this application is applicable. The clamps are positioned close to the CNC lathe and are used to move the blank bar stock 001 moved to the loading tray 320 onto the CNC lathe and to move the machined workpiece 002, which has been processed by the CNC lathe, and place it on top of the basic conveying assembly 100 for conveying.

[0030] The power assembly provides power to the operation of each component of the receiving device applicable to CNC lathes in this application, and the control unit controls the coordinated operation of each component of the receiving device applicable to CNC lathes in this application. Both are existing technologies and will not be described in detail here.

[0031] Preferably, the control unit is a combination of a programmable logic controller and control buttons.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, in order to ensure the stability of the material transported by the basic conveying component 100 and improve its carrying capacity, and to reduce the impact of the deflection of the bearing ring belt 133 on the conveying stability, the receiving device of the CNC lathe applicable to this application also includes one or more support components; the support components are set in the space enclosed by the basic conveying component 100, suspended in the air, and fixed to the ground by rigid brackets, for supporting the bearing ring belt 133; the support components include a horizontal support frame 410 and a top support roller 420 positioned on the top of the horizontal support frame 410; the horizontal support frame 410 is a horizontal rigid strip frame; the top support roller 420 is a horizontal rigid roller body, rotatably connected to the horizontal support frame 410 around its own axis and located on the top of the horizontal support frame 410, with its length direction being the same as the axial direction of the first rotating body 110, and directly contacting the inner ring of the bearing ring belt 133; the presence of the support components can reduce the bending of the bearing ring belt 133 in the horizontal direction.

[0034] Furthermore, such as Figure 5As shown, the material receiving assembly includes a material receiving guide plate 230 and a material distribution and blocking assembly; the material receiving guide plate 230 is an arc-shaped plate with its opening facing obliquely upward, its bottom end fixed to the end of the material carrier 210, and its concave surface coplanar with the top surface of the material carrier 210; the blank bar stock 001 is arranged in rows on the material receiving guide plate 230; the material distribution and blocking assembly is used to transport the blank bar stock 001 to the material carrier 210 in a timed and quantitative manner; the material distribution and blocking assembly includes a first limiting body 250 and a second limiting body 260; the first limiting body 250 and the second limiting body 260 have the same structure, are positioned on the ground and are set at the bottom of the material receiving guide plate 230; the first limiting body 250 is closer to the material carrier 210 than the second limiting body 260; the first The limiting body 250 includes an inclined telescopic frame 251 and a top limiting plate 252; the inclined telescopic frame 251 is an inclined telescopic rod structure that is controlled to extend and retract, thereby driving the top limiting plate 252 to move; the top limiting plate 252 is an inclined rigid plate body, with its bottom fixed to the top of the inclined telescopic frame 251; the material guide plate 230 is positioned with a through slot 231 for the top limiting plate 252 to pass through; the through slot 231 is a through slot; the distance between the two top limiting plates 252 of the first limiting body 250 and the second limiting body 260 is greater than 30 cm; when it is necessary to output the blank bar stock 001 to the loading body 210, the two top limiting plates 252 are controlled to move up and down and reset in sequence, so as to transport the single blank bar stock 001 to the loading body 210.

[0035] Preferred, such as Figure 1 and Figure 2 As shown, the clamping and shifting assembly 500 includes a shifting carrier 510, a connecting telescopic body 520, and a clamping assembly 530; the shifting carrier 510 is a suspended track; the connecting telescopic body 520 is a vertically placed rigid telescopic rod that slides controlled along the shifting carrier 510; the clamping assembly 530 is positioned at the bottom of the connecting telescopic body 520 and is an electric or pneumatic clamp.

[0036] Preferably, the clamping and shifting assembly 500 includes a shifting carrier 510, a connecting telescopic body 520, and a clamping assembly 530; the shifting carrier 510 is a robotic arm positioned on the ground; the connecting telescopic body 520 is a horizontally placed rigid telescopic rod fixed to the arm head of the shifting carrier 510 and controlled to extend and retract; the clamping assembly 530 is positioned at the end of the connecting telescopic body 520 away from the shifting carrier 510.

When clamping, the shifting plates 532 are controlled to slide so that the position of the bottom clamp 533 adapts to the shape of the workpiece 002 for stable clamping.

[0039] Preferably, to further restrict the position of the blank bar 001 on the loading base plate assembly 200 for precise conveying and to reduce the scrap of processing materials due to misalignment, the receiving device for CNC lathes in this application further includes a side guide assembly 600; such as Figure 2 and Figure 6 As shown, there are two side guide components 600, positioned on the ground and located on both sides of the basic conveying component 100; the side guide components 600 are symmetrically arranged and close to the material receiving component; each side guide component 600 includes a bottom rail 610, a vertical frame 620, support rollers 630, and an abutment belt 640; the bottom rail 610 is a horizontal rigid guide rail, positioned on the ground, with its length direction the same as the width direction of the basic conveying component 100; the vertical frame 620 is a rigid frame body, manually or in a controlled sliding position on the bottom rail 610; the support rollers 630 are multiple vertically arranged...

Before the material receiving device of the CNC lathe is used, the position of the side guide component 600 is adjusted according to the length of the blank bar 001 to be transported. When the blank bar 001 moves to a position close to the side guide component 600, it is guided to move laterally by the contact belt 640.

[0040] This application applies to the use of a receiving device for CNC lathes before the following: When the receiving device is matched with a different number of CNC lathes, a different number of side-pushing material loading components and clamping and shifting components 500 need to be set up; the number of side-pushing material loading components and clamping and shifting components 500 is the same as the number of CNC lathes matched; before processing, according to the size specifications of the workpiece 002 to be processed, the adjustable sliding tube 131 is slid and the rotating sleeve 132 is rotated so that one workpiece 002 can be placed between the three adjacent limiting positioning rods 134 located in the three positioning conveying units 130 (that is, the carrier for accommodating the workpiece 002 is shaped by adjusting the positioning conveying unit 130 and using the limiting positioning rods 134); then the sliding and rotation of the adjustable sliding tube 131 and the rotating sleeve 132 are restricted (the two are directly or indirectly fixed on the first rotating body 110 and the second rotating body 120). This application applies to the use of the receiving device on a CNC lathe: During the operation of the basic conveying assembly 100, the operation of the incoming material assembly is controlled. The rotation of the cooperative positioning conveying unit 130 conveys the blank bar stock 001 one by one onto the carrier 210 and rolls between the limiting positioning rods 134 (the area formed by the limiting positioning rods 134 for accommodating the workpiece 002 is insufficient to accommodate the blank bar stock 001, so the blank bar stock 001 rolls in the adjacent area of ​​the aforementioned area); the blank bar stock 001 gradually rolls away from the incoming material assembly under the push (push) of the limiting positioning rods 134. When the blank bar 001 is conveyed close to the CNC lathe, the control side pusher and loading assembly pushes the blank bar 001 out, exposing it. The clamping and shifting assembly 500 clamps and moves the blank bar 001 to fix it on the CNC lathe. After the blank bar 001 is machined into a workpiece 002 by the CNC lathe, the clamping and shifting assembly 500 clamps and moves the workpiece 002 to place it in the area of ​​the basic conveying assembly 100 for accommodating the workpiece 002, and then the basic conveying assembly 100 conveys it away (after reaching the target position, it is removed from the basic conveying assembly 100 by the corresponding equipment).

[0048] Example 2

[0049] In order to transport the workpiece 002 in a specific orientation for subsequent processes (which may require a specific facet of the workpiece 002 to face a specific position for processing), this application embodiment optimizes and improves the structure of the basic conveying assembly 100 based on the above embodiment, specifically as follows: CNC machine tools have a spindle indexing function, which can control the posture (rotation direction) of the workpiece 002 before it is moved away. A rubber sleeve is fitted onto the limiting positioning rod 134; like Figure 12 As shown, when the orientation of the positioning and conveying unit 130 is adjusted to match the workpiece 002, the workpiece 002 can be inserted between the three adjacent limiting positioning rods 134 of the three positioning and conveying units 130 (that is, after the workpiece 002 is inserted, it will squeeze and deform the sheath on the limiting positioning rod 134 and thus be restricted by the limiting positioning rod 134 and cannot move). When the basic conveying assembly 100 carries the workpiece 002, it will only drive it to move horizontally without changing its orientation.

[0053] Preferably, if the workpiece 002 carried by the basic conveying component 100 has a thicker end and a thinner end with a smaller diameter variation, when it approaches the loading component 700, it can be pushed away from the basic conveying component 100 and into the loading device directly from the end with the smaller diameter without the need for the clamping and shifting component 500.

[0054] Preferred, such as Figure 13 As shown, the connecting telescopic body 520 of the clamping and shifting assembly 500 is a vertical telescopic rod; the clamping assembly 530 is rotatably connected to the bottom of the connecting telescopic body 520 around the axis of the connecting telescopic body 520, and rotates under the coordinated control of the power assembly and the control unit; when the clamping and shifting assembly 500 is used to place the workpiece 002, the rotation of the clamping assembly 530 can be controlled as needed to control the placement posture of the workpiece 002.

For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
