Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical tooling, and in particular relates to a positioning and pressing tooling. Background Art

[0002] In welding or processing fixtures, there needs to be clamping when there is positioning, and the most commonly used clamping method is screw clamping. However, if it is an L-shaped workpiece, the clamping point is on the inner side of the L-shape and there is a large part of the workpiece below it, which means that there is a long distance from the clamping seat to the clamping point. During clamping or after welding or processing, the screw must rotate such a long distance to place or take out the workpiece. Whether the screw is clamped or withdrawn for such a long distance, it is very easy to wear, and it is also inconvenient to operate, and the labor efficiency is low. Utility Model Content

[0003] The purpose of the utility model is to solve the defects and shortcomings in the prior art and to design a positioning and pressing tool which is simple in structure, stable and reliable, convenient to operate, efficient and manpower and material saving.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a positioning and clamping tool, including a positioning seat and a clamping mechanism movably arranged on the positioning seat, the positioning seat is provided with an open groove, the clamping mechanism includes a positioning sleeve matching the open groove, a screw threadedly connected to the positioning sleeve, and a pressing block arranged at the end of the screw, when the screw rotates, the positioning sleeve can be limited by the open groove without following the rotation.

[0005] Preferably, the positioning seat comprises a positioning plate and a supporting plate, and the opening groove is a U-shaped groove arranged at the upper end of the positioning plate and opening upward.

[0006] Preferably, the upper and lower ends of the positioning sleeve adopt an arc-shaped structure design that matches the bottom of the U-shaped groove, and the left and right sides of the positioning sleeve adopt a plane structure design that matches the two side walls of the U-shaped groove.

[0007] Preferably, a threaded hole matching the screw rod is provided inside the positioning sleeve.

[0008] Preferably, the width of the positioning sleeve is smaller than the width of the opening slot, and the height of the positioning sleeve is greater than the width of the opening slot.

[0009] Preferably, both front and rear ends of the positioning sleeve are provided with limit blocks, and the two limit blocks are respectively located on the front and rear sides of the positioning plate, that is, the distance between the two limit blocks is greater than the thickness of the positioning plate.

[0010] Preferably, the limit block adopts a circular structure design, and the diameter of the limit block is greater than the width of the opening groove.

[0011] After adopting the above technical solution, the positioning and pressing tool provided by the utility model has the following beneficial effects:

[0012] (1) The utility model has high working efficiency. In the existing clamping tooling, the stroke of the screw rod in clamping and withdrawing is too long, especially when there are many clamping points in a large tire, the labor efficiency is extremely low; while the clamping tooling of the utility model adopts a U-shaped groove structure design on the positioning seat, the clamping mechanism can be taken out upward as a whole, and only a small stroke is required for clamping and withdrawing, which is simple and convenient to operate, greatly improving the working efficiency;

[0013] (2) The utility model has high safety. The existing screw has a long stroke. For convenience, operators will add a movable support rod between the pressing block and the workpiece. On the one hand, it will lead to less than ideal pressing effect. On the other hand, the support rod is easy to slip, which poses a great safety hazard. However, the pressing tool of the utility model has a pressing mechanism that is clamped on the U-shaped groove through a positioning sleeve, which is very safe and reliable.

[0014] (3) The utility model has low loss. The existing screw has a long stroke. The longer the screw thread is used, the easier it is to wear. It is also easy to deform and cause the thread to get stuck. However, the clamping tool of the utility model has a design that the clamping mechanism can be removed as a whole. Only a very short part of the thread between the positioning sleeve and the screw is needed to achieve the clamping work. BRIEF DESCRIPTION OF THE DRAWINGS
