Technical Field
[0001] The utility model relates to the technical field of tooling fixtures, in particular to a tooling fixture convenient for adjusting angles. Background Technique
[0002] When grinding and processing parts, it is often necessary to use tooling fixtures to fix the parts. For example, a Chinese patent with the publication number CN213917076U discloses a multi-angle tooling fixture for machine tools. A rotating table is arranged at the bottom end of the fixture table. When different angle requirements are encountered, the angle of the fixture table can be directly adjusted by rotating the rotating table, and then the angle of the workpiece can be adjusted.
[0003] However, the workpiece itself cannot be flipped during the grinding process. When it is necessary to grind the lower end surface of the workpiece, the staff has to first remove the workpiece from the fixture table, and then install the workpiece after adjusting the angle, which is very time-consuming and inefficient. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a tooling fixture convenient for adjusting angles, which solves the technical problem that the existing tooling fixture is not convenient for adjusting the angle of the workpiece during the clamping process and is not convenient to use.

A workpiece clamping mechanism for fixing the workpiece body is movably installed on the fixture base. An angle adjusting mechanism is arranged below the workpiece clamping mechanism. During workpiece grinding, the workpiece clamping mechanism clamps and fixes the workpiece body. During the grinding process, the angle adjusting mechanism can adjust the angle of the workpiece body. The workpiece clamping mechanism includes a rotating circular shaft movably installed on the fixture base. The upper end of the rotating circular shaft is fixedly installed with an operation platform. A material receiving empty groove for storing grinding debris is opened on the operation platform. Rectangular sliding grooves are symmetrically opened on both sides of the material receiving empty groove. Movable brackets are slidably connected to the rectangular sliding grooves. A driving component is arranged inside the rectangular sliding grooves. Clamping protrusions are movably installed on the movable brackets. When the two movable brackets approach each other, they clamp and fix the workpiece body.
[0006] Preferably, the driving component is a driving lead screw, and the driving lead screw is in threaded cooperation with the movable bracket. When the driving lead screw rotates around its own axis, the movable bracket moves along the rectangular sliding groove.
[0007] Preferably, a micro motor for driving the clamping projection to rotate is provided inside the movable bracket. Initially, the clamping projection is in a fixed state, and it will rotate only when the micro motor is powered on and running.
[0008] Preferably, the angle adjustment mechanism includes a fixed gear ring arranged outside the rotating circular shaft. A driving gear is movably installed on the fixture base. An oil storage cavity is formed inside the fixture base. An oil injection pipeline is arranged beside the driving gear. A pressing piston is slidably connected inside the oil storage cavity. A driving motor for rotating the driving gear is fixedly installed at the lower end of the fixture base. When the rotating circular shaft rotates driven by the driving gear, the angle of the workpiece body will be adjusted.
[0009] Preferably, the oil injection pipeline is communicated with the inside of the oil storage cavity. When the pressing piston moves towards the inside of the oil storage cavity, the lubricating oil will be ejected through the oil injection pipeline.
[0010] Preferably, the driving gear meshes with the fixed gear ring. When the driving gear rotates, the rotating circular shaft and the operating platform will rotate synchronously through the cooperation with the fixed gear ring.

[0013] 2. By setting the angle adjustment mechanism, through the mutual cooperation between the oil storage cavity and the oil injection pipeline, the staff only needs to gently push the pressing piston, and the lubricating oil inside the oil storage cavity can be ejected onto the driving gear through the oil injection pipeline without the need to stop the machine and wait.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1
[0022] The fixture in the prior art is not convenient for adjusting the angle of the workpiece. During the grinding process, the workpiece itself cannot be flipped. When it is necessary to grind the lower end surface of the workpiece, the staff has to first remove the workpiece from the fixture table, wait for the angle to be adjusted, and then install the workpiece, which is very time-consuming and inefficient. To solve this technical defect in the prior art, this embodiment proposes a fixture that is convenient for adjusting the angle, with higher flexibility in angle adjustment, without the need for the staff to disassemble and assemble the workpiece, and is easy to use. The workpiece body 4 is placed on the fixture base 1, and a workpiece clamping mechanism 2 for fixing the workpiece body 4 is movably installed on the fixture base 1. An angle adjustment mechanism 3 is provided below the workpiece clamping mechanism 2. During workpiece grinding, the workpiece clamping mechanism 2 will clamp and fix the workpiece body 4. During the grinding process, the angle adjustment mechanism 3 can adjust the angle of the workpiece body 4.
[0023] In order to clamp and fix the workpiece and be able to flexibly adjust the angle of the workpiece, a workpiece clamping mechanism 2 is provided in this embodiment. Specifically, the workpiece clamping mechanism 2 includes a rotating circular shaft 202 movably installed on the fixture base 1. An operating platform 201 is fixedly installed at the upper end of the rotating circular shaft 202. A material receiving empty groove 203 for storing grinding debris is provided on the operating platform 201. Rectangular sliding grooves 204 are symmetrically provided on both sides of the material receiving empty groove 203. An active bracket 206 is slidably connected to the rectangular sliding grooves 204. A driving component 205 is arranged inside the rectangular sliding grooves 204. The driving component 205 is a driving lead screw. The driving lead screw is in threaded cooperation with the active bracket 206. When the driving lead screw rotates around its own axis, the active bracket 206 will move along the rectangular sliding grooves 204. A clamping convex block 207 is movably installed on the active bracket 206. When the two active brackets 206 approach each other, the workpiece body 4 will be clamped and fixed. A micro motor for driving the clamping convex block 207 to rotate is provided inside the active bracket 206. Initially, the clamping convex block 207 is in a fixed state. Only when the micro motor is powered on and running will the clamping convex block 207 rotate.
[0024] In order to be able to quickly lubricate the driving gear 302 with oil, an angle adjustment mechanism 3 is provided in this embodiment. Specifically, the angle adjustment mechanism 3 includes a fixed gear ring 301 arranged outside the rotating circular shaft 202. A driving gear 302 is movably installed on the fixture base 1. The driving gear 302 meshes with the fixed gear ring 301. When the driving gear 302 rotates, it will, through cooperation with the fixed gear ring 301, cause the rotating circular shaft 202 and the operating platform 201 to rotate synchronously. An oil storage cavity 303 is opened inside the fixture base 1. An oil injection pipeline 304 is arranged beside the driving gear 302. The oil injection pipeline 304 is communicated with the inside of the oil storage cavity 303. When the pressing piston 305 moves towards the inside of the oil storage cavity 303, lubricating oil will be sprayed out through the oil injection pipeline 304. A pressing piston 305 is slidably connected to the inside of the oil storage cavity 303. A driving motor 306 for rotating the driving gear 302 is fixedly installed at the lower end of the fixture base 1. When the rotating circular shaft 202 rotates driven by the driving gear 302, the angle of the workpiece body 4 will be adjusted.
[0025] In this embodiment, as Figure 1 shown, during grinding processing, the worker will place the workpiece body 4 between the two clamping convex blocks 207. Next, the two active brackets 206 will approach the workpiece body 4 simultaneously driven by the driving lead screw, so as to limit and clamp the workpiece body 4.
[0026] Subsequently, the staff will use grinding equipment to grind the workpiece body 4. During the grinding process, if the angle of the workpiece body 4 needs to be adjusted, the driving gear 302 will rotate under the action of the driving motor 306. When the driving gear 302 rotates, it will drive the rotating shaft 202 to rotate synchronously through the cooperation with the fixed gear ring 301. Next, the workpiece body 4 will rotate synchronously with the operating platform 201, thus completing the adjustment of the workpiece angle.
[0027] Moreover, when grinding other surfaces of the workpiece, the clamping protrusion 207 can rotate under the action of the micro motor. When the clamping protrusion 207 rotates, it will cause the workpiece body 4 to flip, thus completing the angle adjustment.
[0028] In this embodiment, by setting the workpiece clamping mechanism 2 and using the mutual cooperation between the clamping protrusion 207 and the driving gear 302, the workpiece can not only rotate synchronously with the operating platform 201, but also flip together with the clamping protrusion 207, with higher flexibility in angle adjustment. There is no need for the staff to disassemble and assemble the workpiece, which is convenient to use. Moreover, in this embodiment, by setting the angle adjustment mechanism 3 and using the mutual cooperation between the oil storage cavity 303 and the oil injection pipeline 304, the staff only needs to gently push the pressing piston 305, and the lubricating oil inside the oil storage cavity 303 can be sprayed onto the driving gear 302 through the oil injection pipeline 304 without stopping for waiting.
[0029] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.
