[0030] A cover plate 4 is disposed on the base 1. The cover plate 4 is provided with multiple processing stations. The processing stations are arranged opposite to the positioning stations 11. Each processing station is provided with multiple processing openings 6. The processing openings 6 are arranged opposite to the positioning grooves 2. The processing openings 6 are used to expose the processing position 31 on the resistor 3 for drilling processing.

[0031] A pressing assembly is disposed on the cover plate 4. The pressing assembly includes multiple pressing parts 7, which are arranged one-to-one with the processing openings 6. The pressing parts 7 are used to press and position the resistor 3 on the positioning groove 2.

[0032] After the positioning pin 21 on the positioning groove 2 of this utility model positions the resistor 3, the cover plate 4 is pressed onto the base 1, and the pressing component 7 presses the resistor 3 tightly and positions it on the positioning groove 2. The processing opening 6 on the cover plate 4 exposes the processing position 31 on the resistor 3 for drilling. Drilling can be completed for multiple batches of products at one time, improving production efficiency and processing accuracy. The pressing component 7 on the cover plate 4 can not only adapt to pressing resistor 3 products of different thicknesses, but also will not cause damage to the products, thus playing a protective role.

[0033] In one embodiment of this utility model, the base 1 is provided with a plurality of positioning rods 12, and the cover plate 4 is provided with positioning holes 13 that match the positioning rods 12. The base 1 and the cover plate 4 are connected by fixing bolts 5. When the cover plate 4 is placed on the base 1, the positioning rods 12 on the base 1 pass through the positioning holes 13, so that the cover plate 4 and the base 1 can be quickly aligned and assembled, thereby improving processing efficiency.

[0034] In one embodiment of this utility model, the base 1 is provided with a fixing screw hole 52, the cover plate 4 is provided with a mounting hole 51 that matches the fixing screw hole 52, the fixing bolt 5 is provided on the mounting hole 51, and a fixing spring 54 is sleeved on the fixing bolt 5. One end of the fixing spring 54 is connected to the cover plate 4, and the other end is connected to the fixing bolt 5.

[0035] Specifically, with the support of the fixing spring 54, only the threaded end 56 of the fixing bolt 5 protrudes from the bottom of the cover plate 4, which avoids the fixing bolt 5 interfering with the positioning of the cover plate 4 and the base plate, and also prevents the fixing bolt 5 from being lost, making it convenient for the base 1 and the cover plate 4 to be repeatedly assembled and fixed.

[0036] In one embodiment of this utility model, the fixing bolt 5 includes a head 55, a guide rod 58, and a threaded end 56, which are connected in sequence.

[0037] In one embodiment of this utility model, a strip groove 22 is provided on the positioning station 11. The strip groove 22 penetrates the middle of each positioning groove 2 to divide the positioning groove 2 into two grooves. The depth of the strip groove 22 is greater than the depth of the positioning groove 2, so that the middle of the resistor 3 located on the positioning groove 2 is in a suspended state.

[0038] Specifically, the depth of the strip groove 22 is greater than the depth of the positioning groove 2, so that the middle part of the resistor 3 located on the positioning groove 2 is suspended, which can dissipate heat from the resistor 3. With the help of a fan or other air blowing equipment, the heat dissipation efficiency can be improved, and the heat accumulation during the processing of the resistor 3 can be avoided, which would affect the product quality.

[0039] In one embodiment of the present invention, a support groove is provided on the strip groove 22, and a support block 23 is provided on the support groove, with the support surface on the support block 23 abutting against the middle of the resistor 3.

[0040] Specifically, select a suitable support block 23 according to the specifications of resistor 3 and place it on the support groove. Then, place the resistor 3 product in the positioning groove 2 of the base 1 in sequence. The support block 23 can support the middle part of resistor 3 to prevent deformation caused by processing heat and ensure processing quality.

[0041] In one embodiment of the present invention, the processing opening 6 includes two waist-shaped grooves 61, which are arranged in parallel on the cover plate 4. The pressing component 7 is arranged between the two waist-shaped grooves 61, and the edge of the waist-shaped groove 61 is provided with a guide slope, so that the waist-shaped groove 61 has a trumpet-shaped structure.

[0042] Specifically, the edge of the waist-shaped groove 61 is provided with a guide slope, so that the waist-shaped groove 61 has a flared structure, which can facilitate drilling. The two waist-shaped grooves 61 are arranged in parallel on the cover plate 4, which can not only ensure the strength of the cover plate 4, but also provide an installation position for the pressing component 7, reducing the manufacturing difficulty of the device.

[0048] Specifically, the long rod 72 and the short rod 73 are connected in the middle to form a cross structure, which can greatly increase the contact area with the resistor 3, making the clamping force on it more uniform and improving the clamping and positioning effect; the receiving groove 41 has two long grooves of the same length, and the length of each long groove is greater than or equal to the length of the long rod 72. The position of the long rod 72 and the short rod 73 can be interchanged by rotating the pressing frame 71 according to the actual resistor 3 specifications. Both the long rod 72 and the short rod 73 can be accommodated in the long groove, which has a wide range of applications.

[0049] In use, select a suitable support block 23 according to the specifications of resistor 3 and place it on the support groove. Then, place resistor 3 into the positioning groove 2 of base 1. The positioning groove 2 and the positioning pin 21 on it are used to quickly position resistor 3. Place cover plate 4 on base 1 so that positioning rod 12 on base 1 passes through positioning hole 13. At this time, the long rod 72 and short rod 73 on pressure frame 71 are pressed against the middle of resistor 3 by spring column 74. Under the support of fixing spring 54, only the threaded end 56 of the fixing bolt 5 protrudes from the bottom of cover plate 4 to avoid the fixing bolt 5 interfering with cover plate. The positioning of the base plate 4 also prevents the loss of the fixing bolts 5, and facilitates repeated assembly and fixing of the base 1 and the cover plate 4. The fixing bolts 5 are screwed into the fixing screw holes 52 using manual or electric wrenches and other parts.
