TECHNICAL FIELD

[0001] The utility model relates to the technical field of machine tool, specifically, relate to a wear -resisting mounting seat. BACKGROUND

[0002] 3R fixture is often used in machining, which includes positioning seat and positioning sheet. Generally, the positioning seat is installed on the machine tool, and the positioning sheet is installed on the tool or other mechanism. When the tool is installed on the machine tool, the positioning sheet is only installed on the positioning seat. Specifically, the connecting surface of the positioning seat is provided with a plurality of positioning blocks. The two sides of the positioning block are inclined, so that the side of the positioning block close to the positioning seat is wider. The positioning sheet is provided with a positioning groove. When the positioning seat and the positioning sheet are connected, the positioning block is inserted into the positioning groove. The close combination of the positioning block and the positioning groove can ensure the accurate positioning of the positioning sheet on the positioning seat.

[0003] Because the tool is often replaced according to the processing requirement, the positioning block is rubbed with the positioning groove for a long time, and then the positioning block is worn. The positioning seat needs to be replaced after the positioning block of the prior art is worn. The cost of the positioning seat is high, and the production cost is also high. SUMMARY

[0004] The utility model aims at providing a wear -resisting mounting seat, which can replace the positioning block.

[0006] A wear -resisting mounting seat, including positioning seat and a plurality of positioning blocks, a plurality of positioning blocks are annularly distributed in the positioning seat, and the positioning block is fixed on the connecting surface of the mounting seat through a screw.

[0007] Further, the positioning seat is provided with a plurality of sliding grooves radially around the center of the connecting surface, the positioning block is slidably arranged in the sliding groove, and the positioning block is fixed in the sliding groove through a screw.

[0008] Further, the positioning block is provided with a strip-shaped through hole, and the length direction of the strip-shaped through hole is parallel to the sliding groove.

[0009] Further, the size of the sliding groove is the same as the size of the positioning block, so that the positioning block can be placed in the sliding groove, and the two sides of the positioning block are symmetrically arranged.

[0010] Further, the positioning block is provided with four positioning blocks, the four sliding grooves are cross-shapedly arranged, and each sliding groove is provided with one positioning block.

[0011] Further, the positioning block is in the shape of a circular truncated cone, and the large diameter end of the positioning block is connected to the connecting surface.

[0012] Further, the positioning blocks are arranged in groups; the positioning blocks in each group are arranged in straight lines; and the straight lines where the positioning blocks are arranged all pass through the center of the positioning seat.

[0013] The technical scheme of the utility model has at least the following advantages and beneficial effects:

[0014] When the positioning precision is reduced due to the wear of the positioning blocks after long-term use, the screws are removed and the positioning blocks are removed, and then the positioning blocks are replaced, so that the positioning seat can still be used after the wear of the positioning blocks, and the production cost is reduced.

[0020] As shown in the drawings, Figures 1-4 The utility model provides a wear -resisting mounting seat, including positioning seat 1 and a plurality of positioning blocks 2. Positioning seat 1 is used to connect machine tool. A plurality of positioning blocks 2 annular distribution is in positioning seat 1. The structure of the mounting seat of this embodiment is basically same with prior art, and the difference point with prior art is as follows.

[0021] The positioning block 2 is fixed to the connecting surface of the mounting seat by a screw. The connecting surface is the surface where the positioning piece 6 connects with the positioning seat 1. Generally, the positioning piece 6 is provided with four positioning grooves 4. The four positioning blocks 2 are distributed in a cross shape. The positioning block 2 is correspondingly provided with four. Each sliding groove is correspondingly provided with a positioning block 2. As shown in the drawings, Figure 2 The positioning block 2 is inclined, so that the positioning block 2 gradually tightens the two side surfaces of the positioning groove 4 after entering the positioning groove 4. The positioning block 2 and the positioning groove 4 automatically achieve the best cooperation in the connection process. The positioning piece 6 is provided with a clamping groove 5 for clamping a workpiece or a tool. The positioning piece 6 and the positioning seat 1 are connected by a screw or other locking mechanism. The specific connection structure is the prior art, and will not be described here in this embodiment.

[0022] When using the wear-resistant mounting base of this utility model, if the positioning block 2 wears down after long-term use, resulting in a decrease in positioning accuracy, the screws can be removed to remove the positioning block 2. The positioning block 2 can then be replaced. This design allows the positioning base 1 to remain usable even after the positioning block 2 wears down, thereby reducing production costs.

[0023] In this embodiment, the positioning base 1 has several radially arranged grooves around the center of its connecting surface. The length direction of the grooves passes through the center point of the positioning base 1. The positioning block 2 is slidably disposed in the groove and is fixed inside the groove by screws. When the positioning block 2 is replaced, it is placed inside the groove and slid to the appropriate position, and then fixed by screws.

[0024] In this embodiment, the positioning block 2 is provided with a strip-shaped through hole 3. For example... Figure 3 As shown, the length of the strip-shaped through hole 3 is parallel to the slide groove. This allows the positioning block 2 to slide along the slide groove to any position where the strip-shaped through hole 3 can align with the screw hole of the positioning seat 1, thereby fixing the positioning block 2 to the positioning seat 1 with screws.

[0025] In this embodiment, the size of the slide groove is the same as the size of the positioning block 2, so that the positioning block 2 can be placed in the slide groove. Figure 2 As shown, the positioning blocks 2 are symmetrically arranged on both sides. The positioning blocks 2 fit perfectly into the groove and conform well to the groove wall. When one side of the positioning block 2 is worn, it can be flipped over, and the other side can be inserted into the groove and secured. At this point, the other side of the positioning block 2 can be used. This makes the positioning blocks 2 more usable.

[0026] This embodiment is another alternative solution. In this embodiment, as... Figure 4 As shown, the positioning block 2 is frustum-shaped. The larger diameter end of the positioning block 2 is connected to the connecting surface. When part of the positioning block 2 is worn, it can be rotated so that the other part of the positioning block 2 corresponds to the positioning groove 4. This makes the positioning block 2 more usable.

[0027] In this embodiment, the positioning blocks 2 are arranged in groups. Several positioning blocks 2 in each group are arranged in a straight line. The straight lines through which the positioning blocks 2 are distributed all pass through the center of the positioning seat 1. That is, when the positioning piece 6 is connected to the positioning seat 1, each positioning groove 4 contains several positioning blocks 2. In practice, the contact area between the surface of the frustum-shaped positioning block 2 and the positioning groove 4 is small, resulting in excessive pressure at the contact point. Using multiple positioning blocks 2 can reduce the pressure and enhance wear resistance and stability.
