Description

Technical Field

[0001] This utility model relates to the field of finger processing technology, specifically to a finger drilling tool. Background Technology

[0002] Contact fingers are an important component of electrical contacts in the field of high-voltage switchgear, such as... Figure 9 As shown, the bottom end faces of the contact finger workpiece have different heights. The bottom end face of the contact finger workpiece is not a planar structure, but rather consists of two end faces of different heights arranged sequentially. The right end face of the bottom of the contact finger workpiece is lower than its left end face. For machining the contact finger workpiece, drilling is required on its upper end face. Due to the non-planar structure of the bottom end face of the contact finger workpiece, there is a difficulty in clamping and positioning it.

[0003] Currently, drilling fixtures are typically used to position the finger workpiece. The finger workpiece is placed in a receiving groove on the top of the drilling fixture, which is used to position the finger workpiece and facilitate drilling. However, with existing technology, after drilling is completed, the structure of the receiving groove restricts the finger workpiece, and the drilling process also presses the finger workpiece tightly, making it difficult to remove it from the receiving groove. This requires workers to spend a lot of time removing the finger workpiece from the receiving groove, which is time-consuming, labor-intensive, and affects the processing efficiency of the finger workpiece. Summary of the Invention

[0004] This invention addresses the problem in existing technologies where it is difficult to remove the finger workpiece from the receiving groove of the drilling fixture after drilling. It provides a finger drilling fixture that can position the finger workpiece, facilitating drilling operations while also making it easy to remove the workpiece from the receiving groove after drilling, saving time and effort and improving the processing efficiency of the finger workpiece.

[0005] To achieve the above objectives, the technical solution of this utility model is: a finger drilling fixture, comprising a drilling cover plate, a base, and a bottom arranged sequentially from top to bottom. Support blocks are symmetrically arranged between the drilling cover plate and the base. The top of the drilling cover plate has several parallel receiving grooves, and a clamping assembly is arranged between two corresponding receiving grooves. The support blocks support the drilling cover plate, and the receiving grooves provide installation positions for the finger workpieces. The shape of the receiving grooves is adapted to the shape of the finger workpieces. By placing the finger workpieces in the receiving grooves, the finger workpieces are positioned. The clamping assembly clamps and positions the finger workpieces, thereby facilitating drilling operations on the finger workpieces.

[0006] A positioning hole is provided at the center of the top of the drilling cover plate, and a pin hole is provided in the receiving groove. A pin extending to the bottom of the drilling cover plate is inserted into the pin hole, and the pin is slidably connected to the drilling cover plate. When the contact workpiece is drilled and pressed into the receiving groove and is difficult to remove, the contact workpiece can be pushed out of the receiving groove by pushing the pin upward, thus facilitating the removal of the contact workpiece from the receiving groove.

[0007] A lead screw is vertically rotatably mounted at the center of the base, with its upper end extending into the positioning hole. The lead screw is connected to the base support, which is located between two support blocks and slidably connected to them. Rotation of the lead screw causes the base support to move up and down. The upward movement of the base support pushes the pin upward, causing the pin to push the touch finger workpiece located in the receiving groove upward, thus ejecting the touch finger workpiece from the receiving groove.

[0008] Furthermore, the top of the base has two symmetrically formed slots that match the support blocks. The support blocks are located within the slots, and the base, support blocks, and drill cover plate are bolted together. The slots provide an installation position for the support blocks, and the base, support blocks, and drill cover plate are fixed together with bolts to form a drilling fixture.

[0009] Furthermore, multiple receiving slots are arranged in a rectangular array on the top of the drill cover plate. The bottom of each receiving slot has a stepped platform and an assembly slot. Symmetrical ear slots are provided at both ends and the middle of each receiving slot, and these ear slots are connected to the receiving slots. The stepped platform and assembly slot are adapted to the left and right end faces of the contact finger workpiece, respectively, thus facilitating the placement of the contact finger workpiece in the receiving slot. The ear slot design facilitates the removal of the contact finger workpiece from the receiving slot by the operator.

[0010] Furthermore, the clamping assembly includes a clamping bolt and a positioning plate movably sleeved on the clamping bolt. A threaded hole is formed between two corresponding receiving slots, and the clamping bolt is threadedly connected to the drilling cover plate through the threaded hole. The length of the positioning plate is greater than the distance between the edges of the two receiving slots. Rotating the positioning plate allows its two ends to be positioned horizontally on top of the contact finger workpieces in the two adjacent receiving slots. Tightening the positioning plate with the clamping bolt simultaneously clamps and positions the two contact finger workpieces, thus preventing displacement of the contact finger workpieces during drilling and ensuring drilling accuracy.

[0011] Furthermore, the lead screw includes a threaded portion and an extension portion and a connecting portion disposed at the upper and lower ends of the threaded portion. The extension portion has a square structure and is located inside the positioning hole. The lower end of the connecting portion is provided with a shoulder. The design structure of the extension portion facilitates the rotation of the lead screw by the operator.

[0012] Furthermore, a rotating hole is provided at the center of the base, and bearing grooves are provided at the top and bottom of the base corresponding to the rotating hole, so that a lead screw can be installed on the base through the function of the rotating hole.

[0013] Furthermore, each of the two bearing grooves is equipped with a bearing, and the connecting part is rotatably connected to the base through the bearing; the lower bearing is located on the top of the shoulder, and the bearing facilitates the rotatable connection between the lead screw and the base, while the shoulder limits the bearing.

[0014] Furthermore, the threaded part is connected to the base support for transmission, and a pressure plate groove is provided at the center of the bottom of the base support. A pressure plate sleeved on the screw is provided in the pressure plate groove. The threaded part is designed to drive the base support to move up and down, and the pressure plate plays a limiting role for the bearing.

[0015] The beneficial effects of this utility model through the above technical solution are as follows: This utility model has a reasonable structure and good performance. It can position the finger workpiece, making it easy to drill the finger workpiece. After the drilling is completed, it is also easy to remove the finger workpiece from the receiving groove, saving time and effort and improving the processing efficiency of the finger workpiece.

[0016] The shape of the receiving groove of this utility model is adapted to the shape of the finger workpiece. The finger workpiece is positioned by placing it in the receiving groove. At the same time, the clamping assembly can clamp and position the finger workpiece. The two ends of the positioning plate are respectively placed horizontally on the top of the finger workpiece in the two adjacent receiving grooves. The positioning plate is tightened by the clamping bolts, which can clamp and position two finger workpieces at the same time. This facilitates drilling operations on the finger workpiece and also prevents the finger workpiece from shifting when drilling.

[0017] In this invention, each receiving groove is equipped with a pin. By using the pins to push the finger workpiece upwards, the finger workpiece can be effectively ejected from the receiving groove. Specifically, by rotating the lead screw, the base moves upwards, and the base can push all the pins upwards. The pins push the finger workpiece located in the receiving groove upwards, thereby ejecting the finger workpiece from the receiving groove. Only one operation is needed to eject the finger workpiece from each receiving groove on the drilling cover plate, achieving the effect of easily removing the finger workpiece from the receiving groove.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-9 As shown, a finger drilling fixture includes a drilling cover plate 7, a base support 6 and a base 1 arranged sequentially from top to bottom. Support blocks 5 are symmetrically arranged between the drilling cover plate 7 and the base 1. The top of the drilling cover plate 7 has several parallel receiving grooves 9, and a clamping component is arranged between two corresponding receiving grooves 9. In this embodiment, the drill cover plate 7, the base 6, and the base 1 are all square structures. There are two support blocks 5, which support the drill cover plate 7. The shape of the receiving groove 9 is adapted to the shape of the finger workpiece. The receiving groove 9 provides a position for the finger workpiece to be assembled. The finger workpiece is positioned by placing it in the receiving groove 9, with the drilled surface of the finger workpiece facing upward and the non-drilled surface facing downward, that is, the non-planar structure of the bottom end face of the finger workpiece facing downward. The clamping assembly clamps and positions the finger workpiece. Two adjacent receiving grooves 9 corresponding to each other are grouped together, that is, a clamping assembly is installed between the two receiving grooves 9 in each group. The clamping assembly can clamp and position the finger workpiece placed in the two adjacent receiving grooves corresponding to each other.

[0021] A positioning hole 8 is provided at the center of the top of the drilling cover plate 7, and a pin hole is provided in the receiving groove 9. A pin 10 extending to the bottom of the drilling cover plate 7 is inserted into the pin hole, and the pin 10 is slidably connected to the drilling cover plate 7. In this embodiment, the positioning hole 8 can position the center position of the drill bit. Both ends of the finger workpiece are drilled. After the finger workpiece is drilled and the clamping assembly releases its clamping and positioning of the finger workpiece, the pin 10 is pushed upward. The pin 10 slides upward in the pin hole, and the upper end of the pin 10 pushes the finger workpiece located in the receiving groove 9 upward, so as to push the finger workpiece out of the receiving groove 9, thereby facilitating the removal of the finger workpiece from the receiving groove 9.

[0022] A lead screw 2 is vertically rotatably mounted at the center of the base 1. The upper end of the lead screw 2 extends into the positioning hole 8. The lead screw 2 is connected to the base support 6. The base support 6 is located between two support blocks 5 and is slidably connected to the support blocks 5. In this embodiment, the upper end of the lead screw 2 extends into the positioning hole 8. The positioning hole 8 also facilitates the rotation of the lead screw 2 by the operator. Rotating the lead screw 2 causes the base 6 to move up and down between the two support blocks 5. When the lead screw 2 causes the base 6 to move upward, the base 6 pushes all the pins 10 upward, and the upper end of the pins 10 lifts the finger workpiece located in the receiving groove 9, thus removing the finger workpiece from the receiving groove 9. After all the finger workpieces in the receiving groove 9 are removed, the lead screw 2 is rotated again, causing the base 6 to move downward. When the base 6 returns to its initial position, the pins 10 also return to their initial position due to their own weight. At this time, the finger workpieces can be placed back in the receiving groove 9 for pressing, positioning, and drilling of the next batch of finger workpieces.

[0023] The top of the base 1 has two symmetrically formed strip grooves 101 that match the support block 5. The support block 5 is located within the strip grooves 101. The base 1, support block 5, and drilling cover plate 7 are bolted together. In this embodiment, the strip grooves 101 provide an installation position for the support block 5, and one end of the strip grooves 101 is also symmetrically fitted with ear grooves 903. When assembling the drilling fixture, the support block 5 is placed within the strip grooves 101 to facilitate the fixing of the base 1, support block 5, and drilling cover plate 7 with bolts.

[0024] Multiple receiving slots 9 are arranged in a rectangular array on the top of the drilling cover plate 7. A step 901 and an assembly slot 902 are provided at the bottom of each receiving slot 9. Ear slots 903 are symmetrically provided at both ends and the middle of each receiving slot 9, and these ear slots 903 are connected to the receiving slot 9. In this embodiment, the step 901 is adapted to the left end face of the bottom of the finger workpiece, and the assembly slot 902 is adapted to the right end face of the finger workpiece. The design structure of the step 901 and the assembly slot 902 facilitates the placement of the finger workpiece in the receiving slot 9, and uses the receiving slot 9 to position the finger workpiece that needs drilling. The pin hole is located at the position corresponding to the step 901 and close to the middle of the receiving slot 9, so that the pin 10 installed in the pin hole can lift the finger workpiece. The ear slots 903 facilitate the manual removal of the finger workpiece from the receiving slot 9 by the operator.

[0025] The clamping assembly includes a clamping bolt 12 and a positioning plate 11 movably sleeved on the clamping bolt 12. A threaded hole is provided between the two corresponding receiving grooves 9. The clamping bolt 12 is threadedly connected to the drill cover plate 7 through the threaded hole. The length of the positioning plate 11 is greater than the distance between the edges of the two receiving grooves 9. Its purpose is to ensure that the positioning plate 11 can simultaneously clamp and position the finger workpiece in the two adjacent corresponding receiving grooves 9. In this embodiment, a through hole is provided in the middle of the positioning plate 11. The positioning plate 11 is fitted onto the clamping bolt 12 through the through hole. When the clamping bolt 12 is loosened, the positioning plate 11 can rotate and slide up and down on the clamping bolt 12. Specifically, when drilling the finger workpiece with a drill bit, after the finger workpiece is placed into the receiving groove 9, the clamping bolt 12 is loosened, and the positioning plate 11 is rotated so that both ends of the positioning plate 11 are respectively rotated to the top of the finger workpiece in the two corresponding adjacent receiving grooves 9. Then, the positioning plate 11 tightens the clamping bolt 12 to press the top end face of the two finger workpieces, thereby achieving the clamping and positioning of the finger workpiece. After drilling the finger workpiece with the drill bit, the operator loosens the clamping bolt 12, allowing the positioning plate 11 to rotate on the clamping bolt 12 and rotate between the two corresponding adjacent receiving grooves 9.

[0026] The lead screw 2 includes a threaded portion 201 and extension portions 202 and connecting portions 203 disposed at the upper and lower ends of the threaded portion 201. The extension portion 202 has a square structure and is located within the positioning hole 8. The lower end of the connecting portion 203 is provided with a shoulder 204. In this embodiment, the extension portion 202 has a square structure to facilitate the rotation of the lead screw 2 by the operator through the extension portion 202. The diameter of the shoulder 204 is larger than the diameter of the connecting portion 203, and the diameter of the connecting portion 203 is larger than the diameter of the threaded portion 201.

[0027] A rotating hole 102 is provided at the center of the base 1, and bearing grooves 103 are provided at the top and bottom of the base 1 corresponding to the rotating hole 102. In this embodiment, the rotating hole 102 matches the connecting part 203, and the rotating hole 102 facilitates the assembly of the lead screw 2 onto the base 1; wherein the bearing groove 103 provides an installation position for the bearing 3, and the depth of the bearing groove 103 at the top is less than the depth of the bearing groove 103 at the bottom.

[0028] Each of the two bearing grooves 103 is equipped with a bearing 3, and the connecting part 203 is rotatably connected to the base 1 through the bearing 3; the lower bearing 3 is located on the top of the shoulder 204. In this embodiment, the bearing 3 facilitates the rotatable connection between the lead screw 2 and the base 1, and the shoulder 204 limits the position of the lower bearing 3.

[0029] The threaded portion 201 is connected to the base support 6 via a transmission connection. A pressure plate groove 601 is provided at the center of the bottom of the base support 6, and a pressure plate 4 is fitted onto the lead screw 2 within the pressure plate groove 601. In this embodiment, the threaded portion 201 facilitates the rotation of the lead screw 2, causing the base support 6 to move up and down. The pressure plate groove 601 provides an installation position for the pressure plate 4, which is rotatably fitted onto the lead screw 2. The pressure plate 4 also serves to limit the movement of the bearing 3 located above it.

[0030] The working principle of this utility model is as follows: First, a finger workpiece to be drilled is placed in each receiving groove 9 on the top of the drilling cover plate 7, with the drilled surface of the finger workpiece facing upwards and the non-drilled surface facing downwards. After the finger workpiece is placed in each receiving groove 9, it is pressed and fixed by the clamping assembly. The clamping bolt 12 is loosened, and the positioning plate 11 is rotated so that both ends of the positioning plate 11 are respectively rotated to the top of the finger workpiece in the corresponding adjacent receiving grooves 9. Then, the clamping bolt 12 is tightened so that both ends of the positioning plate 11 press and position the top end face of the finger workpiece in the corresponding adjacent receiving grooves 9. The center position of the drill bit is positioned through the positioning hole 8, and then the drill bit can be used to drill holes at both ends of the finger workpiece.

[0031] After drilling holes at both ends of each finger workpiece, the clamping assembly is released from its clamping and positioning. The operator can loosen the clamping bolt 12, allowing the positioning plate 11 to rotate on the clamping bolt 12. The positioning plate 11 is then rotated back to the position between the two adjacent receiving slots 9. The finger workpieces can then be removed. The lead screw 2 is rotated to cause the base support 6 to rise, pushing all the pins 10 upwards. The upper ends of the pins 10 lift the finger workpieces located in the receiving slots 9, ejecting them from the slots. After all the finger workpieces are removed, the lead screw 2 is rotated again, causing the base support 6 to descend. When the base support 6 returns to its initial position, the pins 10 also return to their initial position due to their own weight. The finger workpieces can then be placed back into the receiving slots 9 for clamping, positioning, and drilling of the next batch of finger workpieces.

[0032] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
