Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to a positioning device for engineering mechanical processing. Background Technology

[0002] Engineering machining refers to the process of processing workpieces in terms of shape, size, and surface quality using mechanical equipment. Machining is one of the basic processes in manufacturing and is widely used in the manufacture of various parts and products. Machining covers many fields, such as molds, automobiles, aerospace, medical devices, and home appliances. Among them, positioning is a very important part of the machining process and plays an important role in the accuracy of workpiece machining. By using reasonable positioning methods, machining errors can be eliminated and machining accuracy can be improved.

[0003] Currently, the positioning device lacks a rotating mechanism during use, which prevents the workpiece from rotating as necessary during processing. This may result in uneven processing of certain parts of the workpiece, affecting processing accuracy and product quality. Furthermore, the workpiece may need to be clamped and repositioned multiple times during processing, which not only increases the number of operation steps but also prolongs processing time and reduces production efficiency. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A positioning device for engineering machining, comprising:

[0006] The top plate has a bearing embedded in its center, and a shaft is rotatably connected inside the bearing. Several slots are circumferentially opened on the outer side of the shaft, and a limit mechanism is provided on the inner side of the slots.

[0007] A worktable is fixedly connected to the top of the shaft, a fixed clamping block is fixedly connected to the top of the worktable, guide rods are connected to both sides of the top of the worktable near the fixed clamping block, a guide sleeve is slidably connected to the outer side of the guide rod, a movable clamping block is fixedly connected to the outer side of the guide sleeve, and a drive mechanism is provided on the back side of the movable clamping block.

[0008] Four support rods are connected to the bottom of the top plate, and a base is fixedly connected to the end of each support rod. Four casters are connected to the bottom of the base.

[0009] In one possible implementation, the limiting mechanism includes a side plate, the top of which is fixedly connected to a top plate. A through hole is provided inside the side plate, and a connecting rod is slidably connected inside the through hole. One end of the connecting rod is connected to a handle, and the other end of the connecting rod is connected to a back plate. A limiting block is connected to the inner side of the back plate.

[0010] In one possible implementation, a spring is fitted on the outer side of the connecting rod, one end of the spring is fixedly connected to the side plate, and the other end of the spring is fixedly connected to the back plate.

[0011] In one possible implementation, the limiting block is configured as an arc shape.

[0012] In one possible implementation, the drive mechanism includes a fixed plate, the bottom of which is fixedly connected to the worktable. A screw hole is provided inside the fixed plate, and a screw rod is threaded into the screw hole. One end of the screw rod is connected to a rotating wheel, and the other end of the screw rod is rotatably connected to a bearing seat. The back side of the bearing seat is fixedly connected to a movable clamping block.

[0013] In one possible implementation, anti-slip pads are connected to the inner sides of both the fixed clamping block and the movable clamping block.

[0014] In one possible implementation, a slide rail is connected above the top plate near the bearing, a slider is slidably connected inside the slide rail, a pad is connected to the top of the slider, and four fixed rods are circumferentially connected above the pad, with the top ends of the fixed rods fixedly connected to the worktable.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By pulling the handle, the limiting block at one end of the connecting rod can be easily removed from the slot. Through the connection between the shaft and the bearing, the worktable can be easily rotated, thus facilitating the rotation of the workpiece clamped above the worktable. After rotating to the appropriate angle, the handle is released, and the elasticity of the spring drives the limiting block to insert into the slot, completing the positioning of the worktable and ensuring the stability of the workpiece. This avoids the problem of the workpiece not being able to rotate as necessary during processing due to the lack of a rotating mechanism in the positioning device.

[0017] 2. By rotating the wheel, the screw is driven to rotate. Through the connection between the screw and the screw hole, the movable clamping block at one end of the screw can be easily slid forward to fix the workpiece between the fixed clamping block and the movable clamping block. By setting anti-slip pads on the inner side of the fixed clamping block and the movable clamping block, it can better contact the workpiece surface, increase friction, prevent the workpiece from sliding on the clamping block surface, affect the positioning effect, and improve the positioning reliability.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This application provides a positioning device for engineering machining, which solves the problems in the prior art.

[0027] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0028] like Figures 1-4 As shown, an engineering machining positioning device includes:

[0029] The top plate 11 has a bearing 23 embedded in the middle of its interior. The bearing 23 is rotatably connected to a shaft 19. The shaft 19 has several slots 18 circumferentially opened on its outer side, and a limit mechanism is provided on the inner side of the slots 18.

[0030] A worktable 16 is fixedly connected to the top of the shaft 19. A fixed clamping block 1 is fixedly connected to the top of the worktable 16. Guide rods 13 are connected to both sides of the worktable 16 near the fixed clamping block 1. A guide sleeve 12 is slidably connected to the outside of the guide rod 13. A movable clamping block 2 is fixedly connected to the outside of the guide sleeve 12. A drive mechanism is provided on the back side of the movable clamping block 2.

[0031] Four support rods 8 are connected to the bottom of the top plate 11. The end of the support rod 8 is fixedly connected to the base 9. Four casters 10 are connected to the bottom of the base 9 to facilitate the movement of the device and improve its flexibility. Currently, the casters 10 on the market are equipped with a locking device, which can be fixed by rotating the locking screw or pressing the locking button.

[0032] In some examples, the limiting mechanism includes a side plate 21, the top of which is fixedly connected to the top plate 11. A through hole 29 is provided inside the side plate 21, and a connecting rod 25 is slidably connected inside the through hole 29. One end of the connecting rod 25 is connected to a handle 22, and the other end of the connecting rod 25 is connected to a back plate 20. A limiting block 26 is connected to the inner side of the back plate 20. By pulling the handle 22, the limiting block 26 at one end of the connecting rod 25 can be easily removed from the slot 18. Through the connection between the shaft 19 and the bearing 23, the worktable 16 can be easily rotated, thereby facilitating the rotation of the workpiece clamped above the worktable 16.

[0033] In some examples, a spring 24 is fitted on the outside of the connecting rod 25. One end of the spring 24 is fixedly connected to the side plate 21, and the other end of the spring 24 is fixedly connected to the back plate 20. Using the elasticity of the spring 24, after the handle 22 is released, the driving limit block 26 is inserted into the slot 18 to complete the positioning of the worktable 16.

[0034] In some examples, the limiting block 26 is set in an arc shape to facilitate the limiting block 26 to fit tightly against the outside of the shaft 19.

[0035] In some examples, the drive mechanism includes a fixed plate 5, the bottom of which is fixedly connected to the worktable 16. The fixed plate 5 has a screw hole 7 inside, and a screw rod 4 is threadedly connected inside the screw hole 7. One end of the screw rod 4 is connected to a rotating wheel 6, and the other end of the screw rod 4 is rotatably connected to a bearing seat 3. The back side of the bearing seat 3 is fixedly connected to a movable clamping block 2. By rotating the rotating wheel 6, the screw rod 4 is driven to rotate. Through the connection between the screw rod 4 and the screw hole 7, the movable clamping block 2 at one end of the screw rod 4 can be easily driven to slide forward, so as to fix the workpiece between the fixed clamping block 1 and the movable clamping block 2.

[0036] In some examples, anti-slip pads 15 are connected to the inner sides of both the fixed clamping block 1 and the movable clamping block 2. By setting the anti-slip pads 15, they can better contact the workpiece surface, increase friction, prevent the workpiece from sliding on the clamping block surface, affect the positioning effect, and improve the positioning reliability.

[0037] In some examples, a slide rail 17 is connected above the top plate 11 near the bearing 23. A slider 14 is slidably connected inside the slide rail 17. A pad 28 is connected to the top of the slider 14. Four fixing rods 27 are circumferentially connected above the pad 28. The top of the fixing rods 27 is fixedly connected to the worktable 16. The connection between the slide rail 17 and the slider 14 helps to further increase the stability of the worktable 16 during rotation.

[0038] This invention allows the limiting block 26 at one end of the connecting rod 25 to be easily removed from the slot 18 by pulling the handle 22. Through the connection between the shaft 19 and the bearing 23, the worktable 16 can be easily rotated, thereby facilitating the rotation of the workpiece clamped above the worktable 16. After rotating to a suitable angle, the handle 22 is released, and the elasticity of the spring 24 drives the limiting block 26 to be inserted into the slot 18, completing the positioning of the worktable 16 and ensuring the stability of the workpiece. This avoids the problem that the positioning device lacks a rotating mechanism, which would prevent the workpiece from rotating as necessary during processing.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
