Description

Technical Field

[0001] This utility model relates to the field of workpiece production technology, and in particular to a tooling component rotation switching device. Background Technology

[0002] Currently, in the workpiece processing and production process, some non-standard tooling or welding fixtures require workers to switch between fixtures and tooling on the production line. Common switching methods used by workers are as follows: First, using a combination of linear guide rails and sliding plate switching devices; however, this method requires a large amount of space, and some tooling cannot be used in this way due to space constraints. Second, using tools such as wrenches and pin pullers to directly disassemble and assemble parts in their original positions; however, in actual operation, disassembly and assembly are difficult, time-consuming, and labor-intensive, especially when the positioning and clamping parts to be switched are large and heavy, making disassembly and assembly even more difficult.

[0003] Chinese patent CN202121121710.1 discloses a rotary switching tooling structure and production line. The rotary switching tooling structure includes a base, a support, a drive unit, and a locking unit. The base is rotatably fixed to the support and includes at least two mounting surfaces, each capable of mounting a set of fixtures. The drive unit drives the base to rotate, and the locking unit locks the base relative to the support when either mounting surface rotates to the working position. With this rotary switching tooling structure, different fixtures are mounted on different mounting surfaces of the base. When switching fixtures is required, the drive unit is controlled to rotate the base. Once the mounting surface with the desired fixture rotates to the working position, the locking unit locks the base, allowing the desired fixture to be used for product production.

[0004] Although the above tooling structure can achieve rotational switching, it still has the following shortcomings in actual use: the overall structure is complex, the manufacturing cost is high, the economic benefits are low, the locking part has poor performance and is prone to failure, and it is difficult to maintain and has poor practicality. Utility Model Content

A support frame is provided on one side of the base, and a locator is provided at the top of the support frame above the positioning seat. The locator can be connected to the two positioning seats respectively, so as to fix the position of the rotation platform at different angles.

[0007] A further improvement of this utility model is that the rotating mechanism includes an angular contact ball bearing sleeve and a thrust ball bearing sleeve.

The top end of the rotating shaft passes through the thrust ball bearing sleeve and is connected to the rotating platform. The bottom end of the rotating shaft passes through the angular contact ball bearing sleeve and is screwed with a locking nut for fixing the rotating shaft.

[0008] A further improvement of this utility model is that the angular contact bearing unit includes two angular contact ball bearings, which are respectively arranged at the inner top and inner bottom of the angular contact ball bearing sleeve, and a support sleeve is provided between the two angular contact ball bearings.

[0009] A further improvement of this utility model is that the rotating shaft includes shaft body A, shaft body B and shaft body C connected to each other. Shaft body A corresponds to the thrust ball bearing, shaft body B corresponds to the angular contact bearing unit, and shaft body C corresponds to the locking nut. The diameter of shaft body A is larger than the diameter of shaft body B, and the diameter of shaft body B is larger than the diameter of shaft body C, thereby enabling the rotating shaft to form a stepped structure.

[0010] A further improvement of this utility model is that the base has an internally hollow structure, and the bottom end of the rotating shaft can extend into the interior of the base after passing through the angular contact ball bearing sleeve.

[0011] A further improvement of this utility model is that the top of the support frame is provided with a mounting seat for connecting the positioner, and the support frame is connected to the positioner through the mounting seat; the positioner includes a guide sleeve and a positioning pin, the guide sleeve is connected to the mounting seat, the positioning pin is movably inserted inside the guide sleeve, the top of the positioning pin extends out of the guide sleeve and is connected to a handle, the bottom of the positioning pin extends to the outside of the guide sleeve, and the bottom of the positioning pin can be inserted into the positioning seat; a return spring is sleeved on the positioning pin located inside the guide sleeve, the top of the return spring abuts against the top of the guide sleeve, and the bottom of the return spring abuts against the outside of the positioning pin.

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

[0024] Please refer to the attached document. Figure 1-4 The following is a description of a specific embodiment: The tooling component rotation switching device of this utility model includes a base 1, which is combined with an existing tooling base plate platform. The base 1 is installed on the tooling base plate platform. A rotation mechanism is provided at the top of the base 1. The rotation mechanism is connected to a rotation platform 7, which enables the rotation platform 7 to rotate freely.

[0025] Specifically, the rotating mechanism includes an angular contact ball bearing sleeve 3 and a thrust ball bearing sleeve 5. The angular contact ball bearing sleeve 3 is located at the top of the base 1, and the thrust ball bearing sleeve 5 is located at the top of the angular contact ball bearing sleeve 3. An angular contact bearing unit is installed inside the angular contact ball bearing sleeve 3, and a thrust ball bearing 15 is installed inside the thrust ball bearing sleeve 5. A rotating shaft 6 passes through the interior of both the thrust ball bearing 15 and the angular contact ball bearing unit. The top end of the rotating shaft 6 passes through the thrust ball bearing sleeve 5 and connects to the rotating platform 7. The bottom end of the rotating shaft 6 passes through the angular contact ball bearing sleeve 3 and is screwed with a locking nut 16 for fixing the rotating shaft 6. A washer 2 is provided between the locking nut 16 and the angular contact ball bearing sleeve 3. The overall design of the rotating mechanism is reasonable and easy to assemble. It can not only stably support the rotating platform 7 but also ensure that the rotating platform 7 can rotate freely.

[0026] Two workpiece connecting devices are installed on the top surface of the rotating platform 7, and the two workpiece connecting devices are arranged at intervals along the axial direction of the rotating platform 7. Each workpiece connecting device has a positioning seat 10 fixed to the top surface of the rotating platform 7 on its outer side, and the positioning seat 10 corresponds to the position of the workpiece connecting device. It should be noted that the actual arrangement of the two workpiece connecting devices can be selected according to the on-site operation conditions. For example, when the tooling workpiece needs to be switched 180°, the two workpiece connecting devices can be arranged in a centrally symmetrical manner.

[0027] Specifically, the workpiece connecting device includes a connecting block A8 and a connecting block B9. Connecting block A8 is connected to the top surface of the rotating platform 7. Connecting block B9 has an L-shaped structure, with one side connected to connecting block A8 and the other side connected to its adjacent positioning seat 10. Adjusting shims are provided between connecting block B9 and connecting block A8, and between connecting block B9 and positioning seat 10. The above-mentioned workpiece connecting device is reasonably designed, has good stability, and is easy to adjust, thus better meeting the installation requirements of existing workpieces.

[0028] A support frame is provided on one side of the base 1, and a positioner 13 is provided at the top of the support frame above the positioning seat 10. The positioner 13 can be connected to the two positioning seats 10 respectively, so as to fix the position of the rotating platform 7 at different angles.

[0029] Specifically, the top of the support frame is provided with a mounting base 12 for connecting the positioner 13. The support frame is connected to the positioner 13 through the mounting base 12. The positioner 13 includes a guide sleeve 17 and a positioning pin 18. The guide sleeve 17 is connected to the mounting base 12. The positioning pin 18 is movably inserted inside the guide sleeve 17. The top end of the positioning pin 18 extends out of the guide sleeve 17 and is connected to a handle 19. The bottom end of the positioning pin 18 extends to the outside of the guide sleeve 17 and can be inserted into the positioning seat 10. A return spring 21 is sleeved on the positioning pin 18 located inside the guide sleeve 17. The top end of the return spring 21 abuts against the top end of the guide sleeve 17, and the bottom end of the return spring 21 abuts against the outside of the positioning pin 18. The overall structure of the positioner 13 is simple, easy to assemble and convenient to operate. When used with the positioning seat 10, it can stably fix the position of the rotating platform 7. Furthermore, the design of the return spring 21 also provides a reset function, making it highly practical.

[0030] Specifically, a limiting pin 20 is provided on the outer side of the top of the positioning pin 18. A limiting groove A1701 and a limiting groove B1702 are provided on the guide sleeve 17, and the limiting grooves A1701 and B1702 are perpendicular to each other. The limiting pin 20 can be inserted into either the limiting groove A1701 or the limiting groove B1702, thus fixing the positioning pin 18 in different positions. Through the cooperation of the limiting pin 20 with the limiting grooves A1701 and B1702, when the limiting pin 20 is inserted into the limiting groove A1701, the return spring 21 keeps the positioning pin 18 in an inserted state with the positioning seat 10. Conversely, after the positioning pin 18 is removed, when the limiting pin 20 is in the limiting groove B1702, the return spring 21 keeps the positioning pin 18 separated from the positioning seat 10, thereby further improving the convenience of the positioner 13 and facilitating operation by the staff.

[0031] The working principle of this utility model is as follows: Through the design of the rotating platform 7 and the workpiece connection device, the operator can install two different tooling workpieces on the same plane. Since the two workpiece connection devices adopt a centrally symmetrical design, when the operator uses one workpiece connection device, the other workpiece connection device is located on the back, thus avoiding interference. When no switching is required, the positioner 13 is inserted into the positioning seat 10, and under the action of the return spring 21, as well as the limit pin 20 and the limit groove A1701, the positioner 13 and the positioning seat 10 always remain in the inserted state, which is stable and reliable. When switching is required, the operator pulls out the positioner 13 and rotates the rotating platform 7 circumferentially by 180° to complete the switching, which realizes the switching of different tooling parts at the same position. After the switching is completed, the operator inserts the positioner 13 into the positioning seat 10 to complete the positioning.

[0032] In one embodiment, the angular contact bearing unit includes two angular contact ball bearings 14, which are respectively arranged at the inner top and inner bottom of the angular contact ball bearing sleeve 3, and a support sleeve 4 is provided between the two angular contact ball bearings 14. The angular contact bearing unit with the above structure can ensure smooth rotation of the rotating shaft 6, and the support sleeve 4 can support the two angular contact ball bearings 14 to prevent them from tilting.

[0033] In one embodiment, the rotating shaft 6 includes shaft bodies A601, B602, and C603 connected end-to-end. Shaft body A601 corresponds to the thrust ball bearing 15, shaft body B602 corresponds to the angular contact bearing unit, and shaft body C603 corresponds to the locking nut 16. The diameter of shaft body A601 is larger than the diameter of shaft body B602, and the diameter of shaft body B602 is larger than the diameter of shaft body C603, thus enabling the rotating shaft 6 to form a stepped structure. The design of the rotating shaft 6 is reasonable, has high stability, and is easy to assemble.

[0034] In one embodiment, the base 1 has a hollow internal structure, and the bottom end of the rotating shaft 6 extends into the interior of the base 1 after passing through the angular contact ball bearing sleeve 3. The base 1 with the above structure can effectively avoid internal structural components, thereby reducing assembly difficulty.

[0035] In one embodiment, the positioning seat 10 has a mounting hole corresponding to the positioning pin 18, and a bushing 11 is provided inside the mounting hole. The design of the bushing 11 can improve wear resistance and extend the service life of the positioning seat 10.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
