Description

Technical Field

[0001] This application relates to the field of pin milling technology, and in particular to pin milling fixtures. Background Technology

[0002] A pin is a standardized fastener that can be used for static fixed connection or for relative movement with the connected parts. It is mainly used at the hinge joint of two parts to form a hinge connection. Pins are usually locked with cotter pins, which are reliable and easy to disassemble.

[0003] Milling machines are used for machining pins. When machining pins, a fixture is needed to hold the pin blank. If the existing fixture becomes slightly loose during the machining process, it will reduce the machining accuracy of the pin, or even cause the pin to fall out of the fixture and cause a safety accident. Moreover, the fixture needs to be maintained after a period of use. When the clamping block is worn, the entire clamping block needs to be replaced, which increases the cost. Utility Model Content

[0004] To address the issues that existing fixtures, after clamping a pin, may experience slight loosening during machining, leading to reduced pin machining accuracy or even the pin detaching from the fixture and causing a safety accident, and the need for maintenance after a period of use, requiring replacement of the entire clamping block when it wears out, thus increasing costs, this application provides a pin milling fixture.

[0005] The pin milling fixture provided in this application adopts the following technical solution:

[0006] A pin milling fixture includes a U-shaped base. Multiple sets of electric push rods are symmetrically installed on both sides of the U-shaped base, and multiple sets of first clamping seats are symmetrically installed on the inner wall. The output shaft end of the electric push rod passes through the first clamping seat and extends to a fixed seat outside the first clamping seat. A second clamping seat is detachably installed on the side of the fixed seat away from the electric push rod. Arc-shaped grooves for clamping the pin are respectively opened on the opposite sides of the first clamping seat and the second clamping seat.

[0007] Preferably, the first clamping seat has fixing plates at both ends, and the fixing plates are fixedly connected to the inner wall of the U-shaped bottom by bolts.

[0008] Preferably, multiple sets of guide rods are symmetrically installed on the inner wall of the U-shaped bottom, and the first clamping seat and the second clamping seat are slidably sleeved on the guide rods.

[0009] Preferably, a first connecting block is provided in the middle of one side of the second clamping seat, and second connecting blocks are symmetrically provided on both sides of the first connecting block. A first slot matching the first connecting block is provided in the middle of one side of the fixing seat, and second slots matching the second connecting blocks are symmetrically provided on both sides of the first slot.

[0010] Preferably, the fixing block has grooves at both ends, the two second connecting blocks have through holes, the first connecting block has threaded holes at both ends, a fixing screw is installed in the groove, the fixing screw passes through the through hole and extends into the threaded hole for threaded connection.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This pin milling fixture has a simple structure, making it easy to operate, install, and replace. When maintenance is required, the clamping seat that needs maintenance can be disassembled and replaced, thus eliminating the need to replace the entire fixture and reducing the cost of use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution:

[0019] A pin milling fixture includes a U-shaped base 1. Multiple sets of electric push rods 2 are symmetrically installed on both sides of the U-shaped base 1, and multiple sets of first clamping seats 3 are symmetrically installed on the inner wall. The output shaft end of the electric push rod 2 passes through the first clamping seat 3 and extends to the outside of the first clamping seat 3 and is provided with a fixed seat 4. A second clamping seat 5 is detachably installed on the side of the fixed seat 4 away from the electric push rod 2. Arc-shaped grooves 6 for clamping the pin are respectively opened on the opposite side of the first clamping seat 3 and the second clamping seat 5.

[0020] In use, multiple sets of electric push rods 2 are activated to drive the second clamping seat 5 to move away from the first clamping seat 3. Multiple pins are then inserted sequentially into the position between the first clamping seat 3 and the second clamping seat 5, and are positioned within the arc-shaped grooves 6 of the two clamping seats. The multiple sets of electric push rods 2 are then activated to drive the second clamping seat 5 to move towards the first clamping seat 3, thereby clamping and fixing the pins. During use, when it is necessary to replace or maintain the first clamping seat 3 or the second clamping seat 5, they can be disassembled and replaced, thus eliminating the need to replace the entire fixture and reducing the cost of use.

[0021] The first clamping seat 3 has fixing plates at both ends. The fixing plates are fixedly connected to the inner wall of the U-shaped bottom 1 by bolts, which facilitates installation and disassembly.

[0022] Multiple sets of guide rods 7 are symmetrically installed on the inner wall of the U-shaped base 1. The first clamping seat 3 and the second clamping seat 5 are slidably sleeved on the guide rods 7 respectively. When the first clamping seat 3 and the second clamping seat 5 move to clamp, they play a guiding role and improve stability.

[0023] A first connecting block 8 is provided in the middle of one side of the second clamping seat 5, and second connecting blocks 9 are symmetrically arranged on both sides of the first connecting block 8. A first slot 11 matching the first connecting block 8 is provided in the middle of one side of the fixing seat 4, and second slots 12 matching the second connecting blocks 9 are symmetrically arranged on both sides of the first slot 11.

[0024] The fixed base 4 has grooves at both ends, the two second connecting blocks 9 have through holes, and the first connecting block 8 has threaded holes at both ends. The fixing screw 10 is installed in the groove, and the fixing screw 10 passes through the through hole and extends into the threaded hole to be threadedly connected to it.

[0025] During installation, the first connecting block 8 and the second connecting block 8 on one side of the second clamping seat 5 are aligned with the first slot 11 and the second slot 12 respectively and inserted into the interior. The first connecting block 8 and the second connecting block 5 are then connected by the fixing bolt 10 to fix the second clamping seat 5. The structure is simple and easy to operate, install and replace.
