Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example: Reference Figure 1-6 The machine tool fixture shown includes a base plate 1, a fixed clamping plate 2 fixed to the left side of the base plate 1, a carrier plate 3 hinged to the back of the right side of the base plate 1, a screw 4 inserted into the carrier plate 3 and threadedly connected to the screw 4, an auxiliary groove 9 provided on the front side of the carrier plate 3 to provide a leverage point for the worker to flip the carrier plate 3, and a movable clamping plate 5 rotatably connected to the left end of the screw 4 via a bearing, the movable clamping plate 5 being located above the base plate 1, and the right side of the movable clamping plate 5 being fixed. There is a guide rod 6, and the carrier plate 3 has a first sliding groove for the guide rod 6 to slide. By turning the screw 4 with the help of the knob 7, the screw 4 pushes the moving clamp 5 to move closer to the fixed clamp 2, thus completing the clamping of the workpiece on the base plate 1. The guide rod 6 plays a guiding role to prevent the moving clamp 5 from rotating. The right end of the screw 4 is fixed with the knob 7. The carrier plate 3 is equipped with a locking component. The base plate 1 has a through hole 8 that matches the locking component. The locking component is used to lock the position when the base plate 1 and the carrier plate 3 are stacked.

[0025] The carrier plate 3 is mounted on the base plate 1 by means of hinge, so that when the machine tool fixture is cleaning debris, the carrier plate 3 and the clamping plate 5 can be rotated and moved, so that the debris between the two and the base plate 1 is directly exposed, which makes it convenient for workers to clean the debris. The locking component can help lock the position of the base plate 1 and the carrier plate 3, so that the machine tool fixture can remain stable during use.

[0026] The locking assembly includes a spring 10, the bottom end of which is fixedly mounted on the carrier plate 3, the top end of which is fixedly mounted on an end plate 11, and the bottom end of which is fixedly mounted on a rod 12. The spring 10 is sleeved on the outside of the rod 12. The carrier plate 3 has a second sliding groove for the rod 12 to slide. The rod 12 is fitted into the through hole 8. Debris entering the through hole 8 can be discharged along the bottom of the through hole 8. A pull ring 13 is rotatably mounted on the end plate 11. A corrugated telescopic tube A14 is fixed between the carrier plate 3 and the end plate 11. The corrugated telescopic tube A14 is sleeved on the outside of the spring 10.

[0027] The end plate 11 and the insert rod 12 can be lifted together by the pull ring 13, so that the insert rod 12 is disengaged from the through hole 8. In this way, the locking component no longer locks the base plate 1 and the carrier plate 3, and the carrier plate 3 can be flipped over for debris cleaning. When the carrier plate 3 is placed back on the base plate 1, the pull ring 13 is released, and the insert rod 12 can be inserted back into the through hole 8 by the pull of the spring 10, thereby locking the positions of the base plate 1 and the carrier plate 3 and ensuring the stability of the machine tool fixture during use. The use of the corrugated telescopic tube A14 is to prevent debris from entering the second slide groove along the top of the second slide groove.

[0028] Among them, a corrugated telescopic tube B15 is fixed between the carrier plate 3 and the movable clamping plate 5. The corrugated telescopic tube B15 is sleeved on the outside of the screw 4. A corrugated telescopic tube C16 is fixed on the right side of the carrier plate 3. A sleeve 17 is fixed on the right end of the corrugated telescopic tube C16. The sleeve 17 is sleeved on the outside of the knob 7. The joint between the knob 7 and the sleeve 17 is rotatably connected by a bearing. Both the corrugated telescopic tube C16 and the sleeve 17 are sleeved on the outside of the screw 4. The sleeve 17 is provided with a through groove 18 for the screw 4 to pass through.

[0029] The corrugated expansion tube B15 and corrugated expansion tube C16 are used together to wrap the exposed screw 4, preventing debris from adhering to the screw 4 and affecting its use. The sleeve 17 is wrapped around the outside of the knob 7, and the two are connected by a bearing, so that the sleeve 17 can move with the knob 7 but does not rotate synchronously with the knob 7.

[0030] Working principle of this utility model:

[0031] When clamping the workpiece, first place the workpiece on the base plate 1 and make the workpiece close to the fixed clamping plate 2. The worker turns the screw 4 with the knob 7, so that the screw 4 pushes the moving clamping plate 5 closer to the fixed clamping plate 2. During this process, the corrugated expansion tube B15 extends and the corrugated expansion tube C16 retracts until the moving clamping plate 5 cooperates with the fixed clamping plate 2 to firmly clamp the workpiece. After that, the workpiece is processed by the machine tool. Some of the debris generated during the processing falls on the machine tool fixture. After the workpiece is removed, the worker can clean the machine tool fixture.

[0032] The worker uses the pull ring 13 to pull the end plate 11 upwards, causing the end plate 11 to move the insertion rod 12 upwards, causing the insertion rod 12 to leave the through hole 8. At this time, the spring 10 is stretched, and the locking component no longer locks the base plate 1 and the carrier plate 3. The worker holds the auxiliary groove 9 and can rotate the carrier plate 3, causing the carrier plate 3 and the moving clamp 5 to flip over. The worker can then thoroughly clean the machine tool fixture. After cleaning, the worker flips the carrier plate 3 again, so that the carrier plate 3 covers the base plate 1 again. The worker releases the pull ring 13, and the end plate 11 and the insertion rod 12 can move downwards with the help of the spring force of the spring 10, causing the insertion rod 12 to be inserted back into the through hole 8. At this time, the locking component locks the base plate 1 and the carrier plate 3 again.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
