Description

Technical Field

[0001] This utility model specifically relates to a clamping assembly for the production of electrical insulators. Background Technology

[0002] Electrical insulators, also known as dielectrics, are substances that do not conduct current under normal conditions. Their molecules have tightly bound positive and negative charges, very few freely moving charged particles, and extremely high resistivity. This type of material is used as an insulator or to provide insulation in electrical equipment. It is generally used in electronic connectors or communication connection terminals to insulate and fix the communication terminals and improve the transmission stability of communication equipment.

[0003] The production process of electrical insulators involves a series of steps that require clamping and fixing, such as drilling, grinding, and coating. Especially during grinding, traditional clamping components cannot quickly achieve centering and clamping, resulting in eccentricity errors in the fixed position of the electrical insulator when it is clamped, which affects the subsequent grinding quality.

[0004] Therefore, it is necessary to invent an electrical insulator for producing a clamping assembly to solve the above problems. Utility Model Content

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figure 1-7 The invention relates to a clamping assembly for the production of an electrical insulator, comprising a base plate 1, wherein a movable plate 2 capable of translating along the length of the base plate 1 is mounted on the top of the base plate 1.

[0034] The support platform 3 is connected to the top of the movable plate 2 and is used to support the electrical insulator to be clamped.

[0035] The first screw 4 is arranged to pass through the support platform 3 laterally. The first clamping blocks 5 are installed on the outer sides of both the left and right ends of the first screw 4. The two first clamping blocks 5 can move away from each other or move closer to each other along the length of the first screw 4.

[0036] The second screw 6 is longitudinally arranged through the support platform 3. The second clamping blocks 7 are installed on the outer sides of both the front and rear ends of the second screw 6. The two second clamping blocks 7 can move away from each other or move closer to each other along the length direction of the second screw 6, and are used to cooperate with the first clamping block 5 to clamp the electrical insulator.

[0037] It also includes a bracket 8, which is located below the base plate 1. A rotating table 9 is mounted on the top of the bracket 8. The bottom of the base plate 1 is connected to the output end of the rotating table 9 to drive the base plate 1 to rotate, so that the electrical insulator that is subsequently clamped can move freely in a circular motion, thereby allowing the grinding angle to be changed freely as needed.

[0038] In one embodiment, the top of the support platform 3 is provided with a first sliding groove 10 for the movement of the first clamping block 5. The first sliding groove 10 is provided with two sections, left and right. The two side walls of the first clamping block 5 adjacent to the first sliding groove 10 are milled with recesses 11. The top of the support platform 3 is provided with a second sliding groove 12 for the movement of the second clamping block 7. The second sliding groove 12 is provided with two sections, front and back. The two side walls of the second clamping block 7 adjacent to the second sliding groove 12 are also milled with recesses 11. The design of the recesses 11 allows the first clamping block 5 and the second clamping block 7 to slide stably inside the first sliding groove 10 and the second sliding groove 12 without falling off.

[0039] In one embodiment, the height of the first clamping block 5 is greater than that of the second clamping block 7, the first screw 4 is disposed above the second screw 6, and the left and right sections of the first screw 4 are arranged with opposite screw directions, so that when the first screw 4 rotates, the two first clamping blocks 5 move in opposite directions. The front and rear sections of the second screw 6 are arranged with opposite screw directions, so that when the second screw 6 rotates, the two second clamping blocks 7 move in opposite directions.

[0040] In one embodiment, the front and rear sides of the movable plate 2 are bent downward to form folded edges 13. The movable plate 2 is engaged with the base plate 1 through the folded edges 13, which improves the connection strength between the movable plate 2 and the base plate 1, and makes the movable plate 2 have high stability when it moves horizontally on the top of the base plate 1.

[0041] In one embodiment, a third screw 14 is transversely inserted inside the base plate 1, and a connecting block 15 is connected to the bottom middle of the movable plate 2. The third screw 14 is inserted through the connecting block 15, allowing the position of the movable plate 2 at the top of the base plate 1 to be freely controlled, thus meeting the grinding requirements of the electrical insulator. A clearance groove 16 for sliding of the connecting block 15 is provided at the top of the base plate 1. Limiting strips 17 are connected to the front and rear sides of the bottom of the movable plate 2. The limiting strips 17 are trapezoidal in shape to prevent them from disengaging from the limiting grooves 18, thereby preventing the movable plate 2 from disengaging from the base plate 1. A limiting groove 18 for sliding of the limiting strips 17 is provided at the top of the base plate 1. When the movable plate 2 moves horizontally, the limiting strips 17 can slide synchronously inside the limiting grooves 18, thereby ensuring the stability of the movable plate 2 during horizontal movement.

[0042] In one embodiment, each end of the first screw 4, the second screw 6, and the third screw 14 is provided with a handle 19, which facilitates the operator to rotate the first screw 4, the second screw 6, and the third screw 14, thereby facilitating the operation of the electrical insulator production clamping assembly.

[0043] The specific implementation method is as follows: In use, the inner surfaces of both the first clamping block 5 and the second clamping block 7 are set in an arc shape, so that they can better fit against the outer surface of the electrical insulator to be clamped. Specifically:

[0044] The staff placed the electrical insulator that needed to be polished and deburred on the top of the support platform 3, and then rotated the first screw 4 in the forward direction. Since the left and right threads of the first screw 4 are set in opposite directions, rotating the first screw 4 in the forward direction will cause the two first clamping blocks 5 to move closer to each other along the lateral direction of the support platform 3, that is, the two first clamping blocks 5 move towards each other and gradually move towards the center of the support platform 3.

[0045] At the same time, the second screw 6 is rotated in the forward direction. Since the front and rear threads of the second screw 6 are set in opposite directions, rotating the second screw 6 in the forward direction will cause the two second clamping blocks 7 to move closer to each other along the longitudinal direction of the support platform 3. That is, the two second clamping blocks 7 also move towards each other and gradually move towards the center of the support platform 3.

[0046] At this time, as the two first clamping blocks 5 and the two second clamping blocks 7 approach the middle electrical insulator together, the four sides of the electrical insulator are uniformly clamped, forming a symmetrical constraint. That is, the electrical insulator is symmetrically clamped, thus completing the centering clamping of the electrical insulator and effectively avoiding the eccentric error of the electrical insulator.

[0047] Subsequently, the staff used polishing tools to polish the outer surface of the electrical insulator to remove burrs. During polishing, the third screw 14 can be rotated forward to move the moving plate 2 to the right along the length of the base plate 1, and the third screw 14 can be rotated in the opposite direction to move the moving plate 2 to the left along the length of the base plate 1. This allows the electrical insulator to move freely back and forth with the moving plate 2 during polishing, making it compatible with external polishing tools. Furthermore, the rotating table 9 allows the entire base plate 1 to move freely in a circular motion, so that the electrical insulator can still rotate around its own axis after being clamped, thereby further improving the polishing quality of the electrical insulator.

[0048] After the electrical insulator is polished, the workers can rotate the first screw 4 and the second screw 6 in the opposite direction, so that the two first clamping blocks 5 and the two second clamping blocks 7 are moved away from each other, thereby releasing the clamping and positioning of the electrical insulator, so that it can be removed in time and replaced with a new electrical insulator to be polished, thus completing the batch polishing production of the electrical insulator.

[0049] The rotary table 9 achieves horizontal rotation through screw drive or belt drive, which will not be described in detail here. That is, the rotary table 9 is not specifically described. Those skilled in the art can fully understand the specific implementation scheme of the rotary table 9 to achieve horizontal rotation of the base plate 1. Therefore, for the sake of space and to avoid redundancy, the detailed description of the rotary table 9 is omitted and only mentioned in the way of functional limitation.

[0050] This embodiment specifically addresses the problem that in the current production process of electrical insulators, there are a series of processes that require clamping and fixing the electrical insulators, such as drilling, grinding, and coating. In particular, during grinding, traditional clamping components cannot quickly achieve centering and clamping, resulting in eccentricity errors in the fixed position of the electrical insulator when it is clamped, which affects the subsequent grinding quality.

[0051] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
