[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A spiral tap grinding fixture comprises an equipment box 1, a slide plate 2 is installed on one side of the equipment box 1 by bolts, two slide slots 3 are vertically staggered inside the slide plate 2, and clamping components 4 are arranged inside the two slide slots 3. The clamping components 4 include four clamping plates 401 slidably installed at both ends of the two slide slots 3, and the ends of the two slide slots 3 away from each other are fixedly installed with reset springs 403, and the ends of the four reset springs 403 close to each other are fixedly installed on the corresponding clamping plates 401 by screws, and the ends of the four clamping plates 401 away from the anti-slip sheet 402 are fixedly installed with roller frames 404, and the ends of the four roller frames 404 away from each other are rotatably installed with rollers 405, and the outsides of the four rollers 405 are wrapped in the clamping groove 6 opened on one side of the clamping plate 5.

[0022] In this embodiment, a clamping groove 6 having an isosceles trapezoidal cross section is formed on one side of the clamping plate 5 .

[0023] By adopting the above solution, a clamping groove 6 with an isosceles trapezoidal cross section is opened on one side of the clamping plate 5, so that the rotation behavior of the clamping groove 6 is gradually converted into the clamping sliding behavior of the four clamping plates 401, effectively improving the balanced fixing behavior.

[0024] In this embodiment, a screw rod 7 is movably inserted into one side of the clamping plate 5 via a rolling bearing, and one end of the screw rod 7 penetrates the equipment box 1 via a thread.

[0025] By adopting the above scheme, a screw rod 7 is movably inserted into one side of the clamping plate 5 through a rolling bearing, and one end of the screw rod 7 passes through the equipment box 1 through a thread, so that the lateral displacement of the clamping plate 5 can be controlled by rotating the screw rod 7. In addition, the thread opened on the outside of the screw rod 7 is self-locking to avoid rotation due to reaction force during clamping, thereby improving the fixing stability of the four clamping plates 401.

[0026] In this embodiment, a rotating handle 8 is fixedly mounted on one end of the screw rod 7 away from the equipment box 1 , and a protective rubber sleeve is sleeved on the outside of the rotating handle 8 .

[0027] By adopting the above scheme, a rotating handle 8 is fixedly installed on the end of the screw rod 7 away from the equipment box 1, and a protective rubber sleeve is sleeved on the outside of the rotating handle 8, which facilitates the problem of controlling the synchronous rotation of the screw rod 7 by rotating the rotating handle 8, and effectively improves the control response capability.

[0028] In this embodiment, mounting plates 9 are fixedly mounted on both ends of the slide plate 2. Both mounting plates 9 are L-shaped plates, and through holes are formed at the ends of the two mounting plates 9 that are away from each other.

[0029] By adopting the above scheme, mounting plates 9 are fixedly installed at both ends of the slide plate 2. Both mounting plates 9 are L-shaped plates, and through holes are opened at the ends of the two mounting plates 9 that are away from each other. The two mounting plates 9 can be used to fix the equipment at the specified position to avoid the problem of installation tilt and misalignment.

[0030] In this embodiment, the clamping component 4 further includes four anti-slip sheets 402 fixedly mounted on the ends of the four clamping plates 401 close to each other by screws and located on the same side of the slide plate 2. The four anti-slip sheets 402 are all made of silicon carbide.

[0031] By adopting the above scheme, the clamping component 4 also includes four anti-skid sheets 402 which are fixed by screws to the ends of the four clamping plates 401 close to each other and located on the same side of the slide plate 2. The four anti-skid sheets 402 are all made of silicon carbide. The friction force is increased by the anti-skid sheets 402 to avoid the problem of tilting and misalignment caused by insufficient friction when fixing the tap.

[0032] In this embodiment, a support plate is sleeved on the outside of the screw rod 7 and located inside the equipment box 1 through a threaded sleeve, and the bottom end of the support plate is fixed to the bottom end of the inside of the equipment box 1 by screws.

[0033] By adopting the above scheme, a support plate is threadedly connected to the outside of the screw rod 7 and inside the equipment box 1, and the bottom end of the support plate is fixed to the bottom end of the equipment box 1 by screws, so that one end of the screw rod 7 is supported by the support plate, thereby ensuring that the screw rod 7 is always balanced and avoiding the problem of the clamping groove 6 tilting downward during movement.

[0034] In the utility model, when in use, the mounting plate 9 is installed in the working position by bolts, the tap is placed between the four clamping plates 401, and the rotary handle 8 is rotated to make the screw rod 7 synchronously move toward the direction of the four clamping plates 401. The clamping groove 6 opened at one end of the clamping plate 5 clamps the four rollers 405, and controls the four clamping plates 401 to slide along the slide groove 3 in a directional manner until the tap is clamped. After the grinding action is completed, the rotary handle 8 is rotated in the reverse direction to make the four clamping plates 401 disengage from the squeezing of the clamping groove 6, and the four reset tension springs 403 control the clamping plates 401 to disengage from the tap, so that the user can conveniently perform the disassembly action.

[0035] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
