Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and in particular to a high-efficiency machining center for workpieces. Background Technology

[0002] A CNC machining center is a highly efficient automated machine tool consisting of mechanical equipment and a CNC system, specifically designed for machining complex parts. The clamping mechanism of some CNC machining centers typically uses guide rails to drive clamping plates for stable workpiece clamping. To accommodate workpieces of different sizes, the guide rail length needs to be increased. However, the longer the guide rail, the more difficult it is to maintain the clamping force. To ensure stable clamping, the structural requirements for the guide rail also increase accordingly. This necessitates the use of high-quality, high-priced guide rails to clamp workpieces with large spans, but this results in higher costs. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency machining center for workpieces. This high-efficiency machining center can not only clamp, position, and process a group of large-sized workpieces, but also simultaneously clamp, position, and process two groups of small-sized workpieces, thereby meeting different processing needs and improving the convenience and efficiency of processing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-efficiency machining center for workpieces, comprising: a machine base, a three-axis drive assembly disposed above the machine base, and a tool assembly mounted on the three-axis drive assembly. The machine base disposed below the tool assembly is formed by splicing a first base plate and a second base plate arranged in sequence. Each of the first base plate and the second base plate has a strip-shaped through hole extending in the left-right direction on its upper surface. A first movable block and a second movable block are movably disposed in each of the strip-shaped through holes. A bidirectional lead screw extending in the left-right direction is rotatably mounted on the lower surface of each of the first base plate and the second base plate on one side of the strip-shaped through hole. The lower ends of the first movable block and the second movable block are threadedly connected to the corresponding bidirectional lead screw through a first connecting block, so that the first movable block and the second movable block located in the same strip-shaped through hole can move towards each other with the bidirectional lead screw.

[0005] The two first movable blocks are arranged far apart from each other, and the upper surface of each first movable block is higher than the upper surface of the first substrate and the second substrate. The two second movable blocks are arranged close to each other, and the upper surface of each second movable block is lower than the upper surface of the first substrate and the second substrate. Each second movable block has a vertically extending groove on its upper surface. A baffle is movably embedded in the groove and connected to the piston rod of a cylinder. When the baffle moves with the cylinder to the first position, its upper surface is flush with the upper surface of the first substrate and the second substrate. When the baffle moves with the cylinder to the second position, its upper surface is higher than the upper surface of the first substrate and the second substrate.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above scheme, a guide rail is provided on the lower surface of the first substrate and the second substrate on the other side of the strip-shaped through hole, and the lower ends of the first movable block and the second movable block are movably connected to the corresponding guide rail through a second connecting block.

[0008] 2. In the above scheme, each of the guide rails is mounted on the first substrate and the second substrate by fixing blocks respectively disposed at both ends of the guide rail.

[0009] 3. In the above scheme, a clearance groove communicating with the slide is opened on one side surface of the second movable block, one end of a transition plate passes through the clearance groove and is connected to the baffle in the slide, and the other end of the transition plate is connected to the piston rod of the cylinder installed on the second movable block.

[0010] 4. In the above scheme, each of the bidirectional lead screws is rotatably mounted on the first base plate and the second base plate through at least two spaced bearing seats.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This utility model discloses a high-efficiency machining center for workpieces. The machine base is composed of a first base plate and a second base plate arranged sequentially. Each of the first and second base plates has a strip-shaped through-hole extending in a left-right direction on its upper surface. A first movable block and a second movable block located within the same strip-shaped through-hole can move towards each other with a bidirectional lead screw. The two first movable blocks are spaced far apart, and the upper surface of each first movable block is higher than the upper surfaces of the first and second base plates. The two second movable blocks are close together, and the upper surface of each second movable block is lower than the upper surfaces of the first and second base plates. Each of the second movable blocks has a vertically extending groove on its upper surface. A baffle is movably embedded in the groove and connected to the piston rod of a cylinder. When the baffle moves with the cylinder to the first position, its upper surface is flush with the upper surfaces of the first and second base plates. When the baffle moves with the cylinder to the second position, its upper surface is higher than the upper surfaces of the first and second base plates. This allows for the clamping, positioning, and processing of a set of large workpieces, as well as the simultaneous clamping, positioning, and processing of two sets of small workpieces, thereby meeting different processing needs and improving the convenience and efficiency of processing.

[0017] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0018] Example 1: A high-efficiency machining center for a workpiece includes: a machine base 21, a three-axis drive assembly 22 disposed above the machine base 21, and a tool assembly 23 mounted on the three-axis drive assembly 22. The machine base 21, disposed below the tool assembly 23, is formed by splicing a first base plate 1 and a second base plate 2 arranged sequentially. Each of the first base plate 1 and the second base plate 2 has a strip-shaped through hole 3 extending in the left-right direction on its upper surface. A first movable block 41 and a second movable block 42 are movably disposed in each of the strip-shaped through holes 3. A bidirectional lead screw 5 extending in the left-right direction is rotatably mounted on the lower surface of each of the first base plate 1 and the second base plate 2 on one side of the strip-shaped through hole 3. The lower ends of the first movable block 41 and the second movable block 42 are threadedly connected to the corresponding bidirectional lead screw 5 through a first connecting block 61, so that the first movable block 41 and the second movable block 42 located in the same strip-shaped through hole 3 can move towards each other with the bidirectional lead screw 5.

[0019] Two first movable blocks 41 are positioned far apart from each other, and the upper surface of each first movable block 41 is higher than the upper surface of the first substrate 1 and the second substrate 2. Two second movable blocks 42 are positioned close to each other, and the upper surface of each second movable block 42 is lower than the upper surface of the first substrate 1 and the second substrate 2. Each second movable block 42 has a vertically extending groove 8 on its upper surface. A baffle 9 is movably embedded in the groove 8 and connected to the piston rod of a cylinder 10. When the baffle 9 moves with the cylinder 10 to the first position, its upper surface is flush with the upper surface of the first substrate 1 and the second substrate 2. When the baffle 9 moves with the cylinder 10 to the second position, its upper surface is higher than the upper surface of the first substrate 1 and the second substrate 2.

[0020] Each of the first substrate 1 and the second substrate 2 has a guide rail 7 on its lower surface and on the other side of the strip-shaped through hole 3. The lower ends of the first movable block 41 and the second movable block 42 are movably connected to the corresponding guide rail 7 through a second connecting block 62.

[0021] Each of the aforementioned guide rails 7 is mounted on the first substrate 1 and the second substrate 2 by means of fixing blocks 71 respectively disposed at both ends of the guide rail.

[0022] Example 2: A high-efficiency machining center for a workpiece, comprising: a machine base 21, a three-axis drive assembly 22 disposed above the machine base 21, and a tool assembly 23 mounted on the three-axis drive assembly 22. The machine base 21, disposed below the tool assembly 23, is formed by splicing a first base plate 1 and a second base plate 2 arranged sequentially. Each of the first base plate 1 and the second base plate 2 has a strip-shaped through hole 3 extending in the left-right direction on its upper surface. A first movable block 41 and a second movable block 42 are movably disposed in each of the strip-shaped through holes 3. A bidirectional lead screw 5 extending in the left-right direction is rotatably mounted on the lower surface of each of the first base plate 1 and the second base plate 2 on one side of the strip-shaped through hole 3. The lower ends of the first movable block 41 and the second movable block 42 are threadedly connected to the corresponding bidirectional lead screw 5 through a first connecting block 61, so that the first movable block 41 and the second movable block 42 located in the same strip-shaped through hole 3 can move towards each other with the bidirectional lead screw 5.

[0023] Two first movable blocks 41 are positioned far apart from each other, and the upper surface of each first movable block 41 is higher than the upper surface of the first substrate 1 and the second substrate 2. Two second movable blocks 42 are positioned close to each other, and the upper surface of each second movable block 42 is lower than the upper surface of the first substrate 1 and the second substrate 2. Each second movable block 42 has a vertically extending groove 8 on its upper surface. A baffle 9 is movably embedded in the groove 8 and connected to the piston rod of a cylinder 10. When the baffle 9 moves with the cylinder 10 to the first position, its upper surface is flush with the upper surface of the first substrate 1 and the second substrate 2. When the baffle 9 moves with the cylinder 10 to the second position, its upper surface is higher than the upper surface of the first substrate 1 and the second substrate 2.

[0024] A clearance groove 11 communicating with the slide 8 is provided on one side surface of the second movable block 42. One end of a transition plate 12 passes through the clearance groove 11 and is connected to the baffle 9 in the slide 8. The other end of the transition plate 12 is connected to the piston rod of the cylinder 10 installed on the second movable block 42.

[0025] Each of the aforementioned bidirectional lead screws 5 is rotatably mounted on the first substrate 1 and the second substrate 2 via at least two spaced bearing seats 13.

[0026] When it is necessary to process small workpieces, the piston rods of the two cylinders 10 are both in the extended state, so that the two baffles 9 are moved up above the upper surfaces of the corresponding first base plate 1 and second base plate 2 under the drive of the cylinders 10. At the same time, two identical workpieces to be processed are placed on the upper surfaces of the first base plate 1 and the second base plate 2 respectively. The two bidirectional lead screws 5 are rotated by the motor, so that the first movable block 41 and the second movable block 42 on each bidirectional lead screw 5 approach each other until the workpieces to be processed are clamped. Then, the workpieces are processed by the tool assembly 23.

[0027] When a large workpiece needs to be processed, and the clamping mechanism on the first substrate 1 and the second substrate 2 alone is insufficient to clamp the workpiece, the piston rods of the two cylinders 10 are placed in the retracted state so that the two baffles 9 are moved down and retracted under the drive of the cylinders 10 until they are flush with the upper surfaces of the first substrate 1 and the second substrate 2. Then, a large workpiece is placed on the upper surfaces of the first substrate 1 and the second substrate 2. The two bidirectional lead screws 5 are driven by the motor to rotate, and each of them drives the first movable block 41 to approach the workpiece until the workpiece is clamped. Then, the workpiece is processed by the tool assembly 23.

[0028] In summary, two sets of short bidirectional lead screw guides can be used to clamp workpieces of different specifications with a large span, thereby reducing the requirements for guides, reducing costs, and maintaining the stability and holding capacity of clamping force.

[0029] When using the high-efficiency machining center for the above-mentioned workpieces, it can both clamp, position and process a set of large-sized workpieces, and simultaneously clamp, position and process two sets of small-sized workpieces, thereby meeting different processing needs and improving the convenience and efficiency of processing.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
