[0002] Automated equipment is a mechanical and electronic device that can automatically complete operations according to preset programs or instructions. It can reduce human intervention, improve production efficiency and accuracy, and is widely used in manufacturing, logistics and other fields. The positioning fixture of automated equipment is a device installed on the equipment to accurately fix the workpiece. It can ensure the stability of the workpiece position during processing, assembly and other processes, provide a precise benchmark for automated operation, and ensure production quality and efficiency.

[0003] A search revealed Chinese Patent Publication No. CN221474280U, which discloses a positioning fixture for CNC automated equipment. The fixture includes a top plate with rectangular holes on both sides of the top center. A first clamping mechanism is provided on each side of the top plate. By using this structure, the fixture can be quickly adjusted to fit the shape of the workpiece to be clamped, improving its practicality, reducing the time spent changing fixtures, and increasing work efficiency.

[0004] Existing technologies often have the following problems when used:

[0005] The positioning structure of the positioning fixtures used in automated equipment is often relatively simple. Most fixtures can only achieve unidirectional, bidirectional, or circumferential clamping, and cannot perform all-round surrounding positioning and clamping of the workpiece. As a result, it is not easy to form a stable fixation of the workpiece from multiple directions, which can easily lead to positioning deviation of the workpiece and affect the processing quality of the workpiece. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a positioning fixture for automated equipment, which can effectively solve the problem that the positioning structure of the existing positioning fixture is relatively simple, unable to achieve all-round surrounding positioning and clamping, and easily leads to workpiece positioning deviation, affecting the workpiece processing quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a positioning fixture for automated equipment, comprising:

[0009] A base plate, on the upper surface of which a support frame and a fixing frame are fixedly connected, and a multi-directional clamping and positioning assembly is rotatably connected to the top of the fixing frame;

[0010] The multi-directional clamping and positioning assembly includes a first screw rotatably connected to the top of the fixed frame, a first slider threadedly fitted to the outer peripheral wall of the first screw, a plurality of strip-shaped sliding holes opened at the top of the support frame, a guide block slidably connected to each strip-shaped sliding hole, a transmission rod rotatably connected between each guide block and the first slider through a hinge seat, and a vertical plate fixedly connected to the upper end face of each guide block, an arc-shaped clamping plate fixedly connected to the side of each vertical plate facing the center position of the support frame, and an axial positioning component rotatably connected to the top surface of the inner side of the support frame.

[0011] Furthermore, the multi-directional clamping and positioning assembly also includes a servo motor fixedly mounted on the upper surface of the base plate, and the output end of the servo motor is fixedly connected to the lower end of the first screw.

[0012] Furthermore, the axial positioning component includes a second screw rotatably connected to the top surface of the support frame. The lower end of the second screw is fixedly connected to the upper end of the first screw. A second slider is threaded onto the outer peripheral wall of the second screw. Several straight plates are fixedly connected to the outer wall of the second slider, and abutment plates are fixedly connected to the upper ends of the several straight plates.

[0013] Furthermore, the thread helix direction on the second screw is opposite to that on the first screw, and the thread helix angle on the first screw is greater than that on the second screw.

[0014] Furthermore, silicone pads are fixedly connected to the outer surfaces of the arc-shaped clamp and the abutment, and the arc-shaped clamp is made of bendable steel plate.

[0015] Furthermore, the top of the support frame is provided with several through holes, and several straight plates are slidably engaged with the top of the support frame through several through holes.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention incorporates a multi-directional clamping and positioning component. By driving the first screw to rotate, the first slider descends along the screw's axial direction. Through the transmission of several transmission rods, several guide blocks move synchronously closer to the center of the support frame. This allows several vertical plates and several arc-shaped clamping plates to move synchronously closer to the workpiece, enabling omnidirectional circumferential positioning and clamping of the workpiece using the arc-shaped clamping plates. Furthermore, an axial positioning component is included. When the first screw rotates, it also drives the second screw to rotate synchronously, allowing the second slider to rise along the screw's axial direction. This, in turn, drives several straight plates to move the abutment plate upwards synchronously, enabling the abutment plate to simultaneously position and clamp the workpiece axially. This combination of omnidirectional circumferential positioning and clamping provides comprehensive, enveloping positioning and clamping of the workpiece, ensuring its positioning stability and accuracy, and thus guaranteeing the workpiece's processing quality.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 3A positioning fixture for automated equipment includes: a base plate 1, a support frame 2 and a fixing frame 3 fixedly connected to the upper surface of the base plate 1, and a multi-directional clamping and positioning assembly rotatably connected to the top of the fixing frame 3; the multi-directional clamping and positioning assembly includes a first screw 4 rotatably connected to the top of the fixing frame 3, a first slider 5 threadedly fitted to the outer peripheral wall of the first screw 4, and a plurality of strip-shaped sliding holes 6 opened at the top of the support frame 2, with a guide block 7 slidably connected to each strip-shaped sliding hole 6, and each guide block 7 rotatably connected to the first slider 5 through a hinge seat. There is a transmission rod 8, and each guide block 7 has a vertical plate 9 fixedly connected to its upper end face. Each vertical plate 9 has an arc-shaped clamping plate 10 fixedly connected to one side facing the center of the support frame 2. The outer surface of the arc-shaped clamping plate 10 is fixedly connected to a silicone pad. The arc-shaped clamping plate 10 is made of bendable steel plate. The multi-directional clamping and positioning assembly also includes a servo motor 11 fixedly installed on the upper end face of the base plate 1. The servo motor 11 is model 80DK-M07725. The output end of the servo motor 11 is fixedly connected to the lower end of the first screw 4.

[0026] Specifically, the inner surface of the strip-shaped sliding hole 6 and the outer surface of the guide block 7 are coated with a lubricating coating. Therefore, when the guide blocks 7 move relative to the support frame 2, the smoothness of the movement of the guide blocks 7 and the continuity of the circumferential clamping of the workpiece by the arc-shaped clamping plates 10 can be ensured.

[0027] By driving the first screw 4 to rotate, the first slider 5 can descend along the axis of the first screw 4, and through the transmission action of several transmission rods 8, several guide blocks 7 can move, so that several guide blocks 7 can move synchronously closer to the center position of the support frame 2, thereby allowing several vertical plates 9 and several arc-shaped clamping plates 10 to move synchronously closer to the workpiece, so as to use several arc-shaped clamping plates 10 to perform circumferential all-round positioning and clamping of the workpiece.

[0028] An axial positioning component is rotatably connected to the inner top surface of the support frame 2. The axial positioning component includes a second screw 12 rotatably connected to the inner top surface of the support frame 2. The screw 12 has a thread direction opposite to that of the first screw 4, and the thread helix angle of the first screw 4 is greater than that of the second screw 12. The lower end of the second screw 12 is fixedly connected to the upper end of the first screw 4. A second slider 13 is threadedly fitted to the outer peripheral wall of the second screw 12. Several straight plates 14 are fixedly connected to the outer wall of the second slider 13. A stop plate 15 is fixedly connected to the upper end of the several straight plates 14. A silicone gasket is fixedly connected to the outer surface of the stop plate 15. Several through holes are opened at the top of the support frame 2. Several straight plates 14 slide and engage with the top of the support frame 2 through several through holes.

[0029] Specifically, during the lifting and lowering movement of slider 5 and slider 13, since the screw 12 and screw 4 have opposite helical directions and the thread helix angle of screw 4 is greater than that of screw 12, the movement distance of slider 13 is shorter than that of slider 5. This is to avoid excessive upward movement of the workpiece when axially fixing it, and to ensure that the several arc-shaped clamps 10 and abutments 15 can fully position, clamp and fix the workpiece.

[0030] Specifically, when the first slider 5 moves, it can be limited by the sliding cooperation of several guide blocks 7 and strip-shaped sliding holes 6. When the second slider 13 moves, it can be limited by the sliding cooperation of several straight plates 14 and the top of the support frame 2, so as to ensure the linearity and stability of the movement of several arc-shaped clamps 10 and abutment plates 15.

[0031] When screw 4 rotates, it also drives screw 12 to rotate synchronously, so that slider 13 can move upward along the axis of screw 12. This causes the abutment 15 to move upward synchronously through several straight plates 14, allowing the abutment to simultaneously position and clamp the workpiece axially. By coordinating the omnidirectional positioning and clamping of the workpiece, the workpiece can be positioned and clamped in an all-round manner, ensuring the positioning stability and accuracy of the workpiece, which is beneficial to ensuring the processing quality of the workpiece.

[0032] The working principle of this utility model is as follows:

[0033] In use, the circular workpiece to be positioned and processed is first placed on the back plate 15. The servo motor 11 is started and driven to rotate the first screw 4 through the servo motor 11, so that the first slider 5 can descend along the axis of the first screw 4. Through the transmission action of several transmission rods 8, several guide blocks 7 are moved, so that several guide blocks 7 can move synchronously closer to the center position of the support frame 2. In turn, several upright plates 9 and several arc-shaped clamping plates 10 can move synchronously closer to the workpiece, so that several arc-shaped clamping plates 10 can be used to perform circumferential all-round positioning and clamping of the workpiece.

[0034] When screw 4 rotates, it also drives screw 12 to rotate synchronously, so that slider 13 can move upward along the axis of screw 12. This causes the abutment 15 to move upward synchronously through several straight plates 14, allowing the abutment to simultaneously position and clamp the workpiece axially. By coordinating the omnidirectional positioning and clamping of the workpiece, the workpiece can be positioned and clamped in an all-round manner, ensuring the positioning stability and accuracy of the workpiece, which is beneficial to ensuring the processing quality of the workpiece.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
