Description

Technical Field

[0001] This utility model relates to the field of machining positioning tooling technology, specifically a machining positioning kit. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using a mechanical device. However, after machining, the workpiece still needs to be polished and deburred, such as common molds.

[0003] After the mold is processed, the staff needs to polish the mold groove with polishing tools. Currently, the mold is placed on the table and the staff uses a polishing pen to perform fine polishing. In the actual operation, because the mold is placed directly on the table and there are no external limiting parts, the mold is prone to displacement due to misoperation, which will cause polishing errors and damage.

[0004] To address this, we propose a machining positioning kit. Utility Model Content

[0005] One of the technical problems this application aims to solve is that in the present method, the mold is placed on a table and the worker uses a polishing pen to perform fine polishing. However, in the actual operation, because the mold is placed directly on the table and there are no external limiting parts, misoperation can easily cause the mold to shift, resulting in polishing errors and damage.

[0006] To address the aforementioned technical problems, this application provides a machining positioning kit, including a support base, symmetrically distributed rotating seats at one end of the support base, a placement plate on the rotating seats, the placement plate being rotatably connected to the support base, symmetrically distributed support legs on the side of the placement plate away from the rotating seats, the support legs being connectable to the top surface of the support base; a pair of positioning posts on the top side of the placement plate, the positioning posts being adapted to positioning holes on the mold, the ends of the positioning posts being chamfered; and a positioning mechanism, the positioning mechanism being mounted on the placement plate via a mounting bracket in the positioning mechanism, for limiting and fixing the mold on the placement plate.

[0007] In some embodiments, the positioning mechanism further includes an elbow clamp disposed on the mounting frame, a connecting plate disposed at the driving end of the elbow clamp, and plugs adapted to the positioning holes of the mold are disposed at both ends of the bottom surface of the connecting plate, the plugs being cylindrical.

[0008] In some embodiments, symmetrically distributed slide rails are provided on the top of the placement plate, and slide blocks are slidably connected to both slide rails. The mounting bracket is fixedly connected to the two slide blocks, and the toggle clamp can move horizontally through the slide blocks.

[0009] In some embodiments, limiting plates are provided at both ends of the two slide rails, and the slide block can fit into the limiting plates.

[0010] In some embodiments, an adjustment mechanism is further included, which is mounted on the support base via two support plates in the adjustment mechanism, for rotating and adjusting the placement plate.

[0011] In some embodiments, the adjusting mechanism further includes a one-way threaded rod rotatably connected to the two support plates, a threaded connecting plate is provided on the one-way threaded rod, a pair of linkage rods are hinged to the top of the threaded connecting plate, one end of the two linkage rods away from the threaded connecting plate is hinged to the bottom of the placement plate, one end of the one-way threaded rod extends to the outside of the support plate and is fixed with a worm gear, a worm gear meshing with the worm gear is provided on the support base, one end of the worm gear is provided with an operating wheel, and symmetrically distributed guide rods are provided on the support plate, the guide rods being slidably connected to the threaded connecting plate.

[0012] In some embodiments, the support base has an elongated groove coplanar with the worm gear, and a portion of the worm gear is located within the elongated groove.

[0013] In some embodiments, the connector is frustum-shaped.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. By setting a support base and a placement plate, a positioning pin that matches the mold positioning hole, and an elbow clamp and connector that can be moved horizontally to adjust the position, the mold is placed on the placement plate through the positioning pin. The elbow clamp is moved horizontally and pressed to insert the connector into the mold positioning hole on the other side of the mold. This realizes the quick positioning function after the mold is placed, restricts the movement of the mold, and thus avoids the slippage that occurs during the grinding process, reduces grinding errors, and improves practicality.

[0016] 2. Through the set rotating seat, support legs, threaded connecting plate, linkage rod, guide rod, one-way threaded rod, worm gear, worm and operating wheel, the placement plate can be rotated relative to the support base by rotating the operating wheel, and can remain stable after rotation. This makes it convenient for operators to change different perspectives to process and polish the mold, making it easy to observe and operate, and providing convenience for mold processing and polishing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figures 1 to 4 The technical solution provided by this utility model is as follows: A machining positioning kit includes a support base 1, a symmetrically distributed rotating seat 3 at one end of the support base 1, a placement plate 2 on the rotating seat 3, the placement plate 2 being rotatably connected to the support base 1, a symmetrically distributed support leg 5 on the side of the placement plate 2 away from the rotating seat 3, the support leg 5 being connectable to the top surface of the support base 1; a pair of positioning posts 23 are provided on the top side of the placement plate 2, the positioning posts 23 being adapted to the positioning holes on the mold, and the ends of the positioning posts 23 being provided with chamfers 24; it also includes a positioning mechanism 10, the positioning mechanism 10 being mounted on the placement plate 2 through the mounting bracket 9 in the positioning mechanism 10, for limiting and fixing the mold on the placement plate 2.

[0026] In this embodiment, as Figure 1 and Figure 2As shown, the positioning mechanism 10 also includes an elbow clamp 11 mounted on the mounting frame 9. A connecting plate 12 is provided at the driving end of the elbow clamp 11. Both ends of the bottom surface of the connecting plate 12 are provided with plugs 13 that are adapted to the positioning holes of the mold. The plugs 13 are cylindrical. Symmetrically distributed slide rails 6 are provided at the top of the placement plate 2. Slide seats 7 are slidably connected to both slide rails 6. The mounting frame 9 is fixedly connected to the two slide seats 7. The elbow clamp 11 can move horizontally through the slide seats 7. When installing the mold, the positioning device is placed flat on the operating table, the positioning holes on the mold are aligned and fitted onto the positioning post 23, the elbow clamp 11 is moved horizontally, and the elbow clamp 11 is pressed down so that the plugs 13 are aligned and inserted into the positioning holes at the other end of the mold, so that the mold is limited and fixed. Then, normal grinding or polishing work can be carried out.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, limit plates 8 are provided on both ends of the two slide rails 6. The slide block 7 can fit with the limit plates 8. The limit plates 8 have a limiting function and can prevent the slide block 7 from falling off the rail 6.

[0028] In this embodiment, as Figures 1 to 4 As shown, it also includes an adjustment mechanism 15, which is mounted on the support base 1 via two support plates 14, and is used to rotate and adjust the placement plate 2.

[0029] In this embodiment, as Figures 1 to 4 As shown, the adjustment mechanism 15 also includes a one-way threaded rod 19 rotatably connected to two support plates 14. A threaded connecting plate 16 is provided on the one-way threaded rod 19. A pair of linkage rods 17 are hinged to the top of the threaded connecting plate 16. The ends of the two linkage rods 17 away from the threaded connecting plate 16 are hinged to the bottom of the placement plate 2. One end of the one-way threaded rod 19 extends to the outside of the support plate 14 and is fixed with a worm gear 21. A worm 22 that meshes with the worm gear 21 is provided on the support base 1. An operating wheel 20 is provided at one end of the worm 22. A guide rod 18 is symmetrically distributed on the support plate 14. The guide rod 18 is slidably connected to the threaded connecting plate 16.

[0030] In this embodiment, as Figures 1 to 4 As shown, during adjustment, rotating the operating wheel 20 clockwise causes the one-way threaded rod 19 to rotate and drive the threaded connecting plate 16 to move closer to the worm gear 21. As the threaded connecting plate 16 moves, the two linkage rods 17 connected to it gradually transition from an inclined state to a vertical state. During the transition of the two linkage rods 17, the placement plate 2 is lifted up, thereby causing the placement plate 2 to rotate relative to the support base 1. Due to the self-locking structure of the worm gear 21 and worm 22, after stopping the operation of the operating wheel 20, the position of the placement plate 2 after rotating relative to the support base 1 can be fixed.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the support base 1 has a long groove 4 that is coplanar with the worm gear 21. Part of the worm gear 21 is located in the long groove 4. The worm gear 21 is circular and relatively large. This setting can avoid the worm gear 21 from being obstructed from rotating and also increases the operating space on one side of the worm gear 21, which facilitates the installation and subsequent maintenance of the worm gear 21.

[0032] The implementation principle of a machining positioning kit in this application embodiment is as follows: When installing the mold, the positioning device is placed flat on the operating table, the positioning hole on the mold is aligned and sleeved on the positioning post 23, the elbow clamp 11 is moved horizontally, and the elbow clamp 11 is pressed down so that the plug 13 is aligned and inserted into the positioning hole at the other end of the mold, so that the mold is limited and fixed, and then normal grinding or polishing work can be carried out.

[0033] During adjustment, rotating the operating wheel 20 clockwise causes the one-way threaded rod 19 to rotate and drive the threaded connecting plate 16 to move closer to the worm gear 21. As the threaded connecting plate 16 moves, the two linkage rods 17 connected to it gradually transition from an inclined state to a vertical state. During the transition of the two linkage rods 17, the placement plate 2 is lifted, thereby causing the placement plate 2 to rotate relative to the support base 1. Due to the self-locking structure of the worm gear 21 and worm 22, after stopping the operation of the operating wheel 20, the position of the placement plate 2 after rotating relative to the support base 1 can be fixed.

[0034] Example 2:

[0035] Please see Figure 5 The technical solution provided by this utility model is as follows:

[0036] Unlike Embodiment 1, the connector 13 is frustum-shaped. The frustum-shaped connector 13 can improve its compatibility and reduce the precision of the connector 13 when machining relative to the mold positioning hole, thereby reducing the machining difficulty and improving production efficiency.
