[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] Please see Figure 1-4 As shown, this utility model is a balanced assembly crimping fixture for insulating end caps, including a base 1, and further including: a first crimping seat 2 fixedly disposed at the top center of the base 1, and a guide rod 3 fixedly disposed on one side of the top of the first crimping seat 2, a first spring 4 sleeved on the outer surface of the guide rod 3, and a first guide sleeve 5 fixedly connected to the other end of the first spring 4, one end of the first spring 4 being fixedly connected to the upper surface of the top of the first crimping seat 2, and the other end being fixedly connected to the lower surface of the first guide sleeve 5, and the inner side of the first guide sleeve 5 having a diameter that is perpendicular to the outer diameter of the guide rod 3. The first guide sleeve 5 has a hole with a diameter matching the guide rod 3. A second crimping seat 6 is welded to one side of the first guide sleeve 5. A first rubber ring 7 is fixed to the bottom periphery of the second crimping seat 6. A lower crimping seat 8 is distributed above the second crimping seat 6. A second rubber ring 9 is fixed to the bottom periphery of the lower crimping seat 8. Both the first rubber ring 7 and the second rubber ring 9 are made of rubber. A second guide sleeve 10 is welded to the side wall of the lower crimping seat 8. A hole with a diameter matching the outer diameter of the guide rod 3 is opened on the inner side of the second guide sleeve 10. An auxiliary structure is provided in the inner cavity of the first crimping seat 2.
[0024] During operation, the workpieces to be press-fitted are first placed in the slots at the top of the first pressing seat 2 and the slots at the middle of the top of the second pressing seat 6, according to the pressing sequence. Then, under the action of the hydraulic cylinder 15, the lower pressing seat 8 connected to its output end moves longitudinally. At this time, the longitudinal movement of the lower pressing seat 8 drives the second guide sleeves 10, which are symmetrically distributed on both sides, to move longitudinally along the guide rod 3. This, in conjunction with the guide rod 3, improves the stability of the lower pressing seat 8 during longitudinal movement. When the lower pressing seat 8 moves longitudinally to directly above the second pressing seat 6, the second rubber ring 9 squeezes the workpiece to be press-fitted. At this time, under the action of pressure, the second pressing seat 6 moves longitudinally. The second pressing seat 6 then drives the first guide sleeves 5, which are symmetrically distributed on both sides, to move longitudinally along the guide rod 3. This improves the stability of the second crimping seat 6 during longitudinal movement. Then, under the action of the lower crimping seat 8, the second crimping seat 6 drives the first rubber ring 7 at its bottom to contact the workpiece to be crimped inside the first crimping seat 2 and press and limit it. At the same time, the first rubber ring 7 provides simple protection. Under the pressure applied by the lower crimping seat 8, the workpiece used in the crimping of the insulating end cap can be tightly crimped by the two parallel crimping seats. During the longitudinal movement of the second crimping seat 6 along the guide rod 3, the first spring 4 will deform and generate a reverse force. The reverse force generated by the deformation of the first spring 4 serves as a buffer and protection, and also facilitates the subsequent longitudinal reset of the second crimping seat 6.
[0025] The auxiliary structure includes a second spring 11 and a washer 12. The second spring 11 is fixedly connected to the bottom of the inner cavity of the first pressing seat 2, and the other end of the second spring 11 is fixedly connected to the washer 12. When the second spring 11 is deformed to the extreme, the washer 12 can be used to protect the pressed workpiece. The washer 12 can be made of rubber.
[0026] During operation, when the insulating end cap workpiece to be crimped is placed inside the first crimping seat 2, the washer 12 will be pressed down under pressure. At this time, the washer 12 is squeezed by longitudinal pressure, and the second spring 11 fixedly connected to its bottom deforms accordingly. The reverse force generated by the deformation of the second spring 11 can achieve the purpose of buffering and protection. When the workpiece is crimped, the second crimping seat 6 presses down, causing the workpiece to be subjected to longitudinal pressure. At this time, the longitudinal movement of the workpiece to be crimped causes the washer 12 to drive the second spring 11 to deform accordingly. Then, the second spring 11 stops deforming when it reaches its extreme. After the crimping of the insulating end cap workpiece is completed, the second crimping seat 6 separates from the first crimping seat 2. At this time, the reverse force generated by the deformation of the second spring 11 will push the washer 12 in the opposite direction. Then, the washer 12 pushes the crimped workpiece in the opposite direction, pushing the workpiece out of the inner side of the first crimping seat 2 for easy removal later.
[0027] A support rod 13 is fixedly provided on one side of the top of the base 1, and a top plate 14 is fixedly provided on the other end of the support rod 13. The two ends of the support rod 13 are welded to the upper surface of the base 1 and the lower surface of the top plate 14 by welding. The support rod 13 is distributed equidistantly along the center point of the base 1. A hydraulic cylinder 15 is fixedly installed in the middle of the top of the top of the top plate 14. The output end of the hydraulic cylinder 15 is fixedly connected to the middle of the top of the lower pressure seat 8.
[0028] During operation, the hydraulic cylinder 15 facilitates the longitudinal movement of the lower pressure seat 8, while the multiple support rods 13 provide support for the top plate 14.
[0029] The second crimping seat 6 is slidably connected to the guide rod 3 through the first guide sleeve 5, and the guide rod 3 is symmetrically distributed along the vertical center line of the first crimping seat 2;
[0030] During operation, the second crimping seat 6 moves longitudinally under the pressure of the lower crimping seat 8. At this time, the second crimping seat 6 drives the first guide sleeves 5, which are symmetrically distributed on both sides, to slide along the guide rod 3. The movement of the first guide sleeves 5 is used to improve the stability of the second crimping seat 6 during longitudinal movement.
[0031] The lower pressure seat 8 is slidably connected to the guide rod 3 through the second guide sleeve 10, and the lower pressure seat 8 and the second pressing seat 6 are distributed in a flat shape;
[0032] During operation, the longitudinal movement of the lower pressure seat 8 will drive the second guide sleeve 10 to move longitudinally along the guide rod 3, which can facilitate the subsequent improvement of the stability of the lower pressure seat 8 during longitudinal movement.
[0033] The second spring 11 is evenly distributed along the center point of the first crimping seat 2, and the washer 12 is generally annular. The washer 12 and the first crimping seat 2 are connected by the second spring 11.
[0034] During operation, since the washer 12 is slidably connected to the first pressing seat 2 through the second spring 11, and the two ends of the second spring 11 are respectively fixedly connected to the bottom of the washer 12 and the bottom of the inner cavity of the first pressing seat 2, the second spring 11 will deform when the washer 12 moves longitudinally. This deformation, combined with the reverse force generated by the deformation of the second spring 11, serves as a buffer and protection mechanism. It also facilitates the subsequent rebound of the washer 12 by the second spring 11.
[0035] Working principle: First, the workpieces to be press-fitted are placed in the slots at the top of the first pressing seat 2 and the middle slots at the top of the second pressing seat 6, respectively, according to the pressing sequence. Then, under the action of the hydraulic cylinder 15, the lower pressing seat 8 connected to its output end moves longitudinally. At this time, the longitudinal movement of the lower pressing seat 8 drives the second guide sleeves 10, which are symmetrically distributed on both sides, to move longitudinally along the guide rods 3. This, in conjunction with the guide rods 3, improves the stability of the lower pressing seat 8 during longitudinal movement. When the lower pressing seat 8 moves longitudinally to directly above the second pressing seat 6, the second rubber ring 9 will squeeze the workpieces to be press-fitted. At this time, under pressure... Under the action of the lower pressure seat 8, the second pressure seat 6 will move longitudinally. At this time, the second pressure seat 6 will drive the first guide sleeves 5 symmetrically distributed on both sides to move longitudinally along the guide rod 3, thereby improving the stability of the second pressure seat 6 during longitudinal movement. Subsequently, under the action of the lower pressure seat 8, the second pressure seat 6 will drive the first rubber ring 7 set at its bottom to contact the workpiece to be pressed and fitted inside the first pressure seat 2, and press and limit it. At the same time, the first rubber ring 7 will provide simple protection. Under the pressure applied by the lower pressure seat 8, the two parallel pressure seats can be used to press and fit the insulating end cap. The workpiece is subjected to a tight pressing process. During the longitudinal movement of the first guide sleeve 5 along the guide rod 3 driven by the second pressing seat 6, the first spring 4 deforms and generates a reverse force. This reverse force generated by the deformation of the first spring 4 serves as a buffer and protection mechanism, and also facilitates the subsequent longitudinal reset of the second pressing seat 6. When the insulating end cap workpiece to be pressed is placed inside the first pressing seat 2, the washer 12 is pressed down under pressure. At this time, the washer 12 is compressed by the longitudinal pressure, and the bottom of the washer fixedly connected to the second spring 11 deforms accordingly. This deformation, combined with the deformation of the second spring 11, causes the washer 12 to deform. The resulting reverse force serves as a buffer and protection. When the workpiece is press-fitted, the second pressing seat 6 presses down, subjecting the workpiece to longitudinal pressure. At this time, the longitudinal movement of the workpiece causes the washer 12 to deform along with the second spring 11. The second spring 11 then stops deforming when it reaches its maximum deformation. After the workpieces of the insulating end cap are press-fitted, the second pressing seat 6 separates from the first pressing seat 2. At this time, the reverse force generated by the deformation of the second spring 11 will push the washer 12 in the opposite direction. The washer 12 then pushes the press-fitted workpiece in the opposite direction, pushing the workpiece out of the inner side of the first pressing seat 2 for easy removal later.
[0036] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
