Specific implementation manner

[0021] The following will combine the attached drawings in the embodiments of the present utility model Figures 1-4 , and clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0022] As shown in the figure, a clamping device for trimming the contactor housing includes a bracket 1, a support rod 2, a sliding sleeve 3, a tightening plate 4, a first connecting rod 5, and a second connecting rod 6. The support rod 2 is vertically arranged on the bracket 1. The sliding sleeve 3 is longitudinally slidably penetrated through the support rod 2, and a locking bolt 31 that passes through the sliding sleeve 3 and abuts against the support rod 2 is screwed on the sliding sleeve 3. The two first connecting rods 5 are symmetrically distributed on both sides of the support rod 2, and one end of the first connecting rod 5 is hinged to the support rod 2. The two tightening plates 4 are respectively fixedly connected to the other ends of the two first connecting rods 5. The two second connecting rods 6 are symmetrically distributed on both sides of the support rod 2. One end of the second connecting rod 6 is hinged to the first connecting rod 5, and the other end is hinged to the sliding sleeve 3.

[0023] In the above embodiments, the bracket 1 is fixedly installed on the table for use. When trimming the contactor housing, loosen the locking bolt 31 so that the sliding sleeve 3 can slide longitudinally on the support rod 2. Move the sliding sleeve 3 downward to drive the second connecting rod 6 to move and swing. The second connecting rod 6 drives the first connecting rod 5 to swing downward. The first connecting rod 5 drives the pressing plate 4 to swing downward, causing the two pressing plates 4 to close towards the support rod 2 and reducing the distance between the two pressing plates 4. At this time, place the contactor housing to be trimmed upside down on the support rod 2 so that the two pressing plates 4 enter the interior of the contactor housing. Then, move the sliding sleeve 3 upward. The sliding sleeve 3 drives the first connecting rod 5 to swing upward through the second connecting rod 6. The two first connecting rods 5 drive the two pressing plates 4 to swing away from the support rod 2 and simultaneously press against the inner wall of the contactor housing. Then, tighten the locking bolt 31 so that it presses against the support rod 2 to fix the sliding sleeve 3, keeping the pressing plate 4 in the position where it presses against the inner wall of the contactor housing. By pressing the two pressing plates 4 against the inner wall of the contactor housing, the contactor housing is clamped and fixed on the support rod 2. At this time, the worker can more conveniently trim the fixed contactor housing, improving production efficiency. Moreover, by adjusting the distance between the two pressing plates 4, contactor housings of different sizes can be fixed, making this clamping device more adaptable.

[0024] Preferably, a cavity 21 is formed inside the support rod 2. A plurality of sliding grooves 22 that communicate with the cavity 21 and extend longitudinally are provided on the support rod 2. A plurality of sliding rods 32 that are matched with the sliding grooves 22 and pass through the sliding grooves 22 and extend into the cavity 21 are fixedly connected to the inner wall of the sliding sleeve 3. A transmission plate 33 located in the cavity 21 is fixedly connected to the end of the sliding rod 32. A return spring 23 with two ends respectively abutting against the bottom wall of the cavity 21 and the transmission plate 33 is arranged in the cavity 21. When fixing the contactor housing on the support rod 2, when moving the sliding sleeve 3 downward, the sliding sleeve 3 drives the transmission plate 33 to slide downward in the cavity 21 by the downward sliding of the sliding rod 32 in the sliding groove 22. While the transmission plate 33 slides downward, it compresses the return spring 23. After placing the contactor housing upside down on the support rod 2 so that the pressing plate 4 enters the contactor housing, release the sliding sleeve 3. The return spring 23 resets and drives the sliding sleeve 3 to slide upward through the transmission plate 33 and the sliding rod 32, causing the pressing plate 4 to tightly press against the inner wall of the contactor housing, thus facilitating the operation of fixing the contactor housing.

[0025] Preferably, the cross-section of the pressing plate 4 is arc-shaped, which is convenient for placing the contactor housing upside down on the support rod 2 and ensuring that the pressing plate 4 can fully contact the contactor housing when swinging and pressing against the inner wall of the contactor housing, thereby ensuring the stability of fixing the contactor housing.

[0026] Preferably, an anti-slip cushion layer 41 is provided on the outer surface of the pressing plate 4. The anti-slip cushion layer 41 strengthens the friction between the pressing plate 4 and the inner wall of the contactor housing when the pressing plate 4 abuts against the inner wall of the contactor housing, thereby ensuring the stability of fixing the contactor housing.

[0027] Furthermore, the support rod 2 is rotatably provided on the bracket 1.

[0028] Specifically, a first bearing 11 is provided on the bracket 1, and the lower end of the support rod 2 is fixedly connected to the inner ring of the first bearing 11.

[0029] In the above preferred embodiment, after the contactor housing is fixed on the support rod 2, the support rod 2 can be rotated to drive the contactor housing to rotate through the action of the first bearing 11, which is convenient for workers to trim the burrs at different positions of the contactor housing by rotating the contactor housing, thus facilitating the operation during trimming.

[0030] Still further, the first bearing 11 is a spherical plain bearing. A through hole 12 is provided on the bracket 1 below the first bearing 11. The lower end of the support rod 2 passes through the through hole 12 and is connected to a second bearing 13. The second bearing 13 is a ball bearing, and a spring retainer 7 is fixedly connected to the outer ring of the second bearing 13. A plurality of reset tension springs 8 arranged in a circular array along the center of the spring retainer 7 are fixedly connected to the spring retainer 7, and the other ends of the reset tension springs 8 are fixedly connected to the bracket 1.

[0031] In the above preferred embodiment, through the cooperation of the first bearing 11 and the second bearing 13, it is ensured that the support rod 2 can drive the contactor housing fixed thereon to rotate. At the same time, since the first bearing 11 is a spherical plain bearing, the support rod 2 can swing on the bracket 1 while being able to rotate. When the support rod 2 swings, the support rod 2 drives the second bearing 13 and the spring retainer 7 to swing and stretch the reset tension springs 8. By swinging the support rod 2 to drive the contactor housing fixed thereon to swing, the angle of the contactor housing during the trimming operation can be adjusted, which is convenient for workers to trim the burrs at different positions of the contactor housing, thus further facilitating the operation during trimming. After removing the force that pushes the support rod 2 to swing, the reset tension springs 8 reset and drive the support rod 2 to return to the vertical state through the spring retainer 7, which is convenient for the subsequent use of the clamping device.

[0032] Preferably, an arc-shaped handle 9 is fixedly connected to the support rod 2. By holding the handle 9, it is more convenient to rotate and swing the support rod 2, thereby further facilitating the operation during trimming.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
