[0028] As Figures 1 - 3 shown, the present utility model provides a fixture for machining vehicle parts.

[0029] In an exemplary embodiment, the fixture for machining vehicle parts includes:

[0030] A fixed seat;

[0031] A first positioning component, arranged on the fixed seat, for positioning the bottom of the part;

[0032] A second positioning component, arranged on the fixed seat, for positioning the top of the part;

[0033] A clamping component, arranged on the fixed seat. The clamping component includes a first fixing mechanism and a second fixing mechanism. The first fixing mechanism and the second fixing mechanism are located on both sides of the second positioning mechanism. A clamping plate 10 is arranged between the first fixing mechanism and the second fixing mechanism, and the clamping plate 10 can be used to press the part against the second positioning component.

[0034] In this embodiment, by positioning the bottom and top of the part, accurate positioning is achieved, which is beneficial to improving the fixing effect. Then, through the arranged clamping plate 10, the part is closely attached to the positioning component, improving the clamping effect and avoiding position deviation of the part during the hole machining process, which affects the machining accuracy.

[0035] Meanwhile, in this embodiment, the workpiece can be quickly positioned by the first positioning component and the second positioning component, and then clamped by the clamping plate 10 to complete the clamping. Compared with the three-jaw chuck, the disassembly and assembly of parts are more convenient and fast, reducing the labor intensity of the staff.

[0036] Exemplarily, the fixed seat in this embodiment includes a bottom plate 1 and a fixing plate 2 fixedly connected to the bottom plate 1. The first positioning component is arranged on the bottom plate 1, the second positioning component is arranged on the fixing plate 2, an installation plate 5 is provided on the fixing plate 2, and the clamping mechanism is arranged on the installation plate 5. The fixed seat is integrally in a "T" shape, with the bottom being the bottom plate 1, and the fixing plate 2 is perpendicular to and integrally provided with the bottom plate 1.

[0037] In an exemplary embodiment, the first fixing mechanism includes a first fixed seat 6 and a first adjusting screw 7. The first fixed seat 6 is detachably connected to the installation plate 5. One end of the first adjusting screw 7 is threadedly connected to the first fixed seat 6, and the other end is hinged to the clamping plate 10.

[0038] In this embodiment, the first fixed seat 6 is detachably connected to the installation plate 5 by screws. By threadedly connecting the first adjusting screw 7 to the first fixed seat 6, the length of the first adjusting screw 7 protruding out of the first fixed seat 6 can be adjusted. When adjusting, only the first adjusting screw 7 needs to be rotated to adjust the length of the first adjusting screw 7 protruding out of the first fixed seat 6, so as to adjust the position of the clamping plate 10, enabling the clamping plate 10 to clamp parts of different models.

[0039] Exemplarily, in this embodiment, a first fixing nut 8 is further provided on the first adjusting screw 7, which can lock the first adjusting screw 7 to prevent it from rotating and ensure the clamping effect of the clamping plate 10.

[0040] Exemplarily, in this embodiment, the free end of the first adjusting screw 7 is fixed to the clamping plate 10 through a first pin shaft 9, and the clamping plate 10 can rotate around the first pin shaft 9.

[0041] In an exemplary embodiment, the second fixing mechanism includes a second fixed seat 11 and a second adjusting screw 12. The second fixed seat 11 is detachably connected to the installation plate 5. One end of the second adjusting screw 12 is threadedly connected to the second fixed seat 11, and the other end is provided with a fork seat 14, and a locking mechanism for fixing the clamping plate 10 is provided on the fork seat 14.

[0042] In this embodiment, the second fixed seat 11 is also detachably connected to the installation plate 5 by screws. The second adjusting screw 12 has the same working principle as the first adjusting screw 7, and its length protruding out of the second fixed seat 11 can be adjusted by rotation. Moreover, through the provided socket and retracting mechanism, the clamping plate 10 is fixed, enabling the clamping plate 10 to clamp the parts.

[0043] Exemplarily, in this embodiment, a second fixing nut 13 is further provided on the second adjusting screw 12, which can lock the second adjusting screw 12 to prevent it from rotating and ensure the fixing effect of the clamping plate 10.

[0044] Exemplarily, a connection groove 1001 is formed at the free end of the clamping plate 10. The locking mechanism includes a fixing rod 16 and a locking member. One end of the fixing rod 16 is hinged to the fork seat 14, and the other end of the fixing rod 16 can pass through the connection groove 1001 and be connected to the clamping plate 10 through the locking member. The fixing rod 16 is hinged to the socket through the second pin shaft 15. Therefore, the fixing rod 16 can rotate around the second pin shaft 15. After the fixing rod 16 rotates into the connection groove 1001, it is locked by the locking member at the end of the fixing rod 16. The locking member is a locking nut 17 threadedly connected to the fixing rod 16, and a gasket 18 is provided between the locking nut 17 and the clamping plate 10. When the locking nut 17 is rotated, the locking nut 17 presses the gasket 18 tightly against the clamping block to realize the fixing of the clamping block.

[0045] Exemplarily, a pressing block 22 is provided on the clamping plate 10, and the pressing block 22 can be used to make the top of the part abut against the second positioning component to realize fixation.

[0046] It should be noted that in this embodiment, when fixing the clamping plate 10, it is necessary to ensure that the clamping plate 10 is in a horizontal state, so as to ensure that the pressing block 22 can apply a positive pressure to the part and ensure the fixing effect of the part.

[0047] In an exemplary embodiment, the first positioning component includes a first fixing block 3 and a first positioning block 4. The first fixing block 3 is detachably connected to the bottom plate 1, the first positioning block 4 is detachably connected to the first fixing block 3, and a first positioning groove 401 for positioning the part is formed on the first positioning block 4 to position the bottom of the part.

[0048] The first fixing block 3 in this embodiment is used to install the first positioning block 4, and the part is positioned and preliminarily fixed through the positioning groove on the first positioning block 4.

[0049] Exemplarily, as Figure 1 shown, in this embodiment, the number of the first positioning blocks 4 is two, which are installed at the left and right ends of the first fixing block 3 and are specifically connected by screws. The first positioning blocks 4 are both provided with first positioning grooves 401, and the first positioning grooves 401 are "V"-shaped grooves, which can make full contact and limit with the part to position the bottom of the part.

[0050] It should be noted that in this embodiment, the number of the first positioning blocks 4 can be adaptively set according to the specific structure of the part. At the same time, in order to adapt to the shape of the part, the first fixing block 3 is inclined along the inclined direction of the part.

[0051] It should also be noted that in this embodiment, the first fixing block 3 is detachably connected to the bottom plate 1 by screws, and the position of the first fixing block 3 can be changed to position parts of different shapes and sizes.

[0052] In an exemplary embodiment, the second positioning assembly includes a second fixing block 19 and a second positioning block 20. The second fixing block 19 is detachably connected to the fixing plate 2, and the second positioning block 20 is detachably connected to the second fixing block 19.

[0053] In this embodiment, the second positioning block 20 is mainly installed on the fixing plate 2 by screws. Specifically, the screws are fixed on the mounting plate 5 and pass through the fixing plate 2 to connect with the second positioning block 20.

[0054] Exemplarily, in this embodiment, a second positioning groove 21 for positioning parts is formed between the second positioning blocks 20, which is used to position the top of the parts. After the fixing clamping plate 10 is fixed, the pressing block 22 presses against the top of the part, making the top of the part closely abut against the two second positioning blocks 20, thus realizing the fixation of the part.

[0055] It is worth noting that after the part is fixed through the above steps, a special U-drill machine tool is used to drill from the head of the workpiece. This method requires a short drill bit or a small equipment stroke, and it is relatively easy for the equipment to meet the requirements. At the same time, the spindle speed of the special U-drill machine tool is high (up to 900 revolutions per minute), the tool uses a replaceable insert with a tool body + cemented carbide material, the feed is large (up to 0.6 mm / revolution), and the drilling efficiency is nearly 5 times higher than that of a vertical drill press. Compared with a vertical drill press, when using a special machine tool, the loading and unloading of the workpiece are simple. After the tool is worn or damaged, the insert is replaced, and the labor intensity of the operator is low.

[0056] In summary, the present utility model positions the bottom and top of the part, and then fixes it through the clamping plate 10, realizing the rapid clamping and disassembly of the part, while ensuring the stability during the processing process and improving the processing accuracy of the part.

[0057] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
