The clamping device includes a first clamping block, a second clamping block, a connecting rod, and a screw. The first clamping block is connected to the first support plate via the connecting rod, and the second clamping block is connected to the second support plate via the connecting rod. The first and second clamping blocks are laterally opposite to each other, and a circular groove is provided in the center of each clamping block. This invention can achieve the beneficial effects of clamping workpieces of various shapes, improving production efficiency, production quality, and production safety.

[0004] However, existing fixtures still have some drawbacks: they cannot flip power devices, are inconvenient for comprehensive processing, and have poor practicality. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the prior art, the present invention provides a clamping device for processing power devices, which aims to solve the problems of not being able to flip power devices, inconvenience in comprehensive processing, and poor practicality.

[0006] To achieve the above-mentioned utility model objectives, the technical solution adopted by this utility model is as follows: a clamping device for processing power devices, including an operating table, a lifting frame fixedly connected to the bottom end of the operating table, a lifting mechanism installed on the lifting frame, a fixing plate one fixedly installed at one end of the upper surface of the operating table, a fixing seat one installed on one side of the fixing plate one, a rotating mechanism provided at the other end of the fixing plate one, a displacement mechanism fixedly installed at the end of the upper surface of the operating table away from the fixing plate one, a fixing plate two connected to the displacement mechanism, and a fixing seat two rotatably connected to one side of the fixing plate two;

[0007] The rotating mechanism includes a rotating shaft sleeved on a fixed plate, one end of the rotating shaft being fixedly connected to a fixed base, and a rotating rod sleeved on the other end of the rotating shaft. A limit plate is installed at one end of the rotating rod, and a drive plate is installed at the other end of the rotating rod. A return spring is connected between the drive plate and the rotating shaft.

[0008] Furthermore, the lifting mechanism includes a support plate fixedly installed on the lifting frame, a drive motor fixedly installed on the support plate, a threaded rod connected to the output end of the drive motor through the support plate, a lifting cylinder fixedly connected to the bottom end of the operating platform, and the top end of the threaded rod being threadedly connected to the lifting cylinder.

[0009] Furthermore, the displacement mechanism includes a mounting base fixedly installed on the upper surface of the operating table. An electric push rod is fixedly installed at one end of the mounting base. The extended end of the electric push rod is fixedly connected to a second fixed plate. A slider is provided at the bottom end of the second fixed plate. A guide rail matching the slider is provided on the upper surface of the operating table.

[0010] Furthermore, a threaded rod 2 is installed on the fixed base 1, and a rotating handle is fixedly installed at the top of the threaded rod 2. A sliding groove is provided on one side of the fixed base 1. A lifting block is threadedly connected to the threaded rod 2. A clamping plate 1 is connected to one end of the lifting block. A rubber pad is provided on the lower surface of the clamping plate 1. A clamping plate 2 is connected to the bottom of one side of the fixed base 1.

[0011] Furthermore, a switch base is provided on one side of the fixing plate, and the switch base is inserted and connected to the limiting plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model discloses a clamping device for processing power devices. Pulling the limiting plate disengages it from the switch base. Rotating the limiting plate causes a rotating rod to rotate the drive plate, which in turn rotates the shaft. This causes the power device on the fixed base to flip, simultaneously compressing the return spring. After adjusting the position, the return spring returns to its original state, causing the limiting plate at one end of the rotating rod to insert into the switch base, thus limiting and fixing the fixed base.

[0014] This utility model discloses a clamping device for processing power devices. Activating the electric push rod causes the slider at the bottom of the second fixed plate to slide smoothly along the guide rail, thereby adjusting the position between the second fixed seat and the first fixed seat. This allows the device to adapt to power devices of different shapes, sizes, and processing requirements, improving the flexibility and applicability of clamping. Rotating the handle causes the threaded rod to rotate, which in turn causes the lifting block to move up and down within the slide groove. The clamping plate second, located at the bottom of one side of the first fixed seat, cooperates with the first clamping plate to achieve the clamping function. Attached Figure Description

A return spring 605 is connected between the drive plate 604 and the rotating shaft 601.

[0027] Through the above scheme, the limiting plate 603 drives the drive plate 604 to rotate, which can drive the power device on the fixed seat 5 to flip. At the same time, the limiting plate 603 at one end of the rotating rod 602 is inserted into the inside of the switch seat 401 to limit and fix the fixed seat 5.

[0028] The lifting mechanism 3 includes a support plate 301 fixedly installed on the lifting frame 2. A drive motor 302 is fixedly installed on the support plate 301. The output end of the drive motor 302 passes through the support plate 301 and is connected to a threaded rod 303. A lifting cylinder 304 is fixedly connected to the bottom end of the operating platform 1. The top end of the threaded rod 303 is threadedly connected to the lifting cylinder 304.

[0029] Through the above scheme, the drive motor 302 drives the threaded rod 303 to rotate, and then the lifting cylinder 304 moves the operating table 1 up and down to achieve precise height adjustment.

[0030] The displacement mechanism 7 includes a mounting base 701 fixedly installed on the upper surface of the operating table 1. An electric push rod 702 is fixedly installed at one end of the mounting base 701. The extended end of the electric push rod 702 is fixedly connected to the fixed plate 8. A slider 704 is provided at the bottom end of the fixed plate 8. A guide rail 703 matching the slider 704 is provided on the upper surface of the operating table 1.

[0031] Through the above scheme, the electric push rod 702 adjusts the position between the fixed base 2 9 and the fixed base 1 5, so that the device can adapt to power devices of different shapes, sizes and processing requirements, and improve the flexibility and applicability of clamping.

[0032] A threaded rod 501 is installed on the fixed base 5. A rotating handle 502 is fixedly installed on the top of the threaded rod 501. A sliding groove 503 is provided on one side of the fixed base 5. A lifting block 505 is threadedly connected to the threaded rod 501. A clamping plate 506 is connected to one end of the lifting block 505. A rubber pad 507 is provided on the lower surface of the clamping plate 506. A clamping plate 504 is connected to the bottom of one side of the fixed base 5.

[0033] Through the above scheme, the clamping plate 2 504 on the bottom side of the fixed base 5 cooperates with the clamping plate 1 506 to achieve the clamping function.

[0034] A switch base 401 is provided on one side of the fixed plate 4, and the switch base 401 is inserted and connected to the limit plate 603.

[0035] Through the above scheme, the switch base 401 and the limit plate 603 are connected by insertion to control the stop position of the rotating mechanism 6.

[0036] The working principle of this utility model patent is as follows: First, the drive motor 302 is started, and the operating table 1 is adjusted to a suitable initial height through the lifting mechanism 3. Then, the electric push rod 702 is operated, and the fixed plate 8 and the fixed seat 9 are adjusted to the position corresponding to the fixed seat 5 through the displacement mechanism 7. The power device to be processed is placed between the fixed seat 5 and the clamping plate 504 to ensure accurate device positioning. Then, the rotating handle 502 is rotated, and the lifting block 505 and the clamping plate 506 are driven to descend through the threaded rod 501 until the clamping plate 506 and the clamping plate 504 tightly clamp the power device. If it is necessary to adjust the processing angle of the power device, the limiting plate 603 is pulled to disengage the limiting plate 603 from the switch seat 401. By rotating the limiting plate 603, the drive plate 604 is rotated through the rotating rod 602, which in turn drives the rotating shaft 601 to rotate, which can cause the power device on the fixed seat 5 to flip over, while compressing the return spring 605. After the position is adjusted, the return spring 605 returns to its original state, causing the limiting plate 603 at one end of the rotating rod 602 to insert into the interior of the switch base 401, thus limiting and fixing the fixed base 5. At this time, the limiting plate 603 and the switch base 401 are engaged and locked at the same angle. To ensure the accuracy of the angle, tools such as an angle gauge can be used for measurement.
