Detailed Implementation

[0020] 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.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a clamping device for processing electric heating tubes, including a base 1, a round shaft 2 rotatably connected to the middle of the top of the base 1, a worktable 3 fixedly connected to the top of the round shaft 2, and a drive assembly connecting the round shaft 2 and the base 1. The drive assembly enables the round shaft 2 to drive the worktable 3 to rotate. A top groove 4 is provided on the top of the worktable 3, and two columns 5 are arranged inside the top groove 4. A first brake motor 6 is fixedly installed on the top of the column 5, and a rotating shaft 7 is fixedly sleeved on the output shaft of the first brake motor 6. A clamping assembly is provided at the other end of the rotating shaft 7, and the clamping assembly can clamp and fix the electric heating tube.

[0022] Once the heating element is clamped and fixed, when the worker processes different positions on the surface of the heating element, there is no need to walk around the heating element. The first brake motor 6 can be activated to make the rotating shaft 7 rotate, thereby adjusting the angle of the clamped heating element. Similarly, the worktable 3 can be rotated through the drive component, so that the worker can rotate the position of the heating element that needs to be processed to the front, which facilitates the processing work.

[0023] Furthermore, the drive assembly includes a second brake motor 8, which is fixedly mounted on the top of the base 1. The output shaft of the second brake motor 8 is fixedly sleeved with a rotating shaft 9, and the other end of the rotating shaft 9 is fixedly connected to a drive gear 10. A driven gear 11 is fixedly sleeved on the top of the outer surface of the round shaft 2, and the driven gear 11 and the drive gear 10 are meshed together.

[0024] By activating the second brake motor 8, the rotating shaft 9 can drive the driving gear 10 to rotate, which in turn causes the driven gear 11 to drive the round shaft 2 and the worktable 3 to rotate. This, in turn, causes the electric heating tube clamped on the worktable 3 to rotate, so that different positions face the worker, making it easier for the worker to process different positions on the surface of the electric heating tube.

[0025] Furthermore, the clamping assembly includes a frame 12, which is fixedly mounted on the rotating shaft 7. Electric push rods 13 are fixedly mounted on both sides of the frame 12. The telescopic ends of the electric push rods 13 are fixedly connected to clamping plates 14, and gaskets 15 are fixedly mounted on the clamping plates 14.

[0026] By placing part of the heating element between two opposing pads 15 and then activating the electric push rod 13, the two clamping plates 14 can move the two pads 15 toward each other to clamp and fix the heating element, thus ensuring the stability of the heating element during processing.

[0027] Furthermore, the width of the gasket 15 is the same as the width of the clamping plate 14, and the surface of the gasket 15 is provided with anti-slip texture.

[0028] The gasket 15 can be made of rubber. Because rubber is soft and elastic, it can provide good protection for the heating element when clamping it.

[0029] Furthermore, a drive motor 16 is fixedly installed on the left side of the workbench 3. The output shaft of the drive motor 16 is fixedly sleeved with a bidirectional lead screw 17. The other end of the bidirectional lead screw 17 extends into the top groove 4. Two columns 5 are respectively threaded onto both sides of the outer surface of the bidirectional lead screw 17.

[0030] By starting the drive motor 16 to rotate the bidirectional lead screw 17, the two columns 5 can move towards or away from each other, thereby adjusting the distance between the two frames 12 and clamping heating tubes of different sizes, thus improving the applicability of the device.

[0031] Furthermore, a slide rail 18 is fixedly installed at the bottom of the inner wall of the top groove 4, and the column 5 is slidably connected to the slide rail 18.

[0032] Furthermore, an annular groove 19 is provided at the top edge of the base 1, and a support rod 20 is fixedly installed at the bottom of the worktable 3. The bottom end of the support rod 20 extends into the interior of the annular groove 19, and the outer surface of the support rod 20 is slidably connected to the inner wall of the annular groove 19.

[0033] The design of the strut 20 makes the worktable 3 more stable when rotating.

[0034] Working principle and usage process of this utility model:

[0035] First, the operator needs to adjust the distance between the two frames 12 according to the size of the heating element. This can be done by starting the drive motor 16 to rotate the bidirectional lead screw 17, causing the two columns 5 to move the two frames 12 towards or away from each other. After adjusting the two frames 12 to a suitable distance for the heating element, part of the heating element is placed between two opposing pads 15. Then, the electric push rod 13 is activated, causing the two clamping plates 14 to move the two pads 15 towards each other, clamping and fixing the heating element. The surface of the heating element can then be processed. When processing different parts of the heating element surface, the operator can start the second... The brake motor 8 causes the rotating shaft 9 to drive the drive gear 10 to rotate, which in turn causes the driven gear 11 to drive the round shaft 2 and the worktable 3 to rotate. This, in turn, causes the electric heating tube clamped on the worktable 3 to rotate, so that different positions face the operator, making it easier for the operator to process different parts of the surface of the electric heating tube. When it is necessary to process the top or bottom of the electric heating tube, the operator can start the first brake motor 6 to rotate the rotating shaft 7, so that the clamped electric heating tube can rotate around the rotating shaft 7 as the axis, adjusting the angle of the electric heating tube, making it easier for the operator to process its top or bottom, further facilitating the processing work.

[0036] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
