Description

Technical Field

[0001] This utility model relates to a pin drilling and positioning device, specifically an automotive pin drilling and positioning device, belonging to the field of pin technology. Background Technology

[0002] A pin is a standardized fastener that can provide both static fixation and relative movement with the connected parts. It is primarily used at the hinge joints of two parts to form a hinge connection. Pins are typically locked with cotter pins, ensuring reliable operation and easy disassembly. Pins are generally installed using either a press-in method or by hammering them in with a soft metal tool.

[0003] The utility model patent CN219026013U provides a pin drilling and positioning device, belonging to the field of pin machining technology. The pin drilling and positioning device positions the pin and includes: a support plate, a fixing plate, a positioning seat, a cylinder, a clamping plate, a guide rod, and a limiting plate. This reduces production costs and avoids using a lathe tailstock drill bit to machine the end of the pin, thus improving the machining efficiency of the pin.

[0004] During the production of automotive pins, drilling is performed to fix the pins in order to ensure their stability. Although the positioning device in the aforementioned patent improves processing efficiency, the size range of automotive pins is large. Using the same device to fix pins of different diameters requires data adjustment, and the positioning accuracy is prone to fluctuation. Therefore, we provide an automotive pin drilling and positioning device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automotive pin drilling and positioning device to solve the problems mentioned above, thereby addressing the issues raised in the prior art.

[0006] This utility model is achieved through the following technical solution: a drilling and positioning device for automotive pin shafts.

[0007] The device includes a machine tool worktable and a fixed base. The surface of the fixed base is fixedly connected with equidistantly arranged support bases. A power mechanism is provided in the middle of the fixed base. The power mechanism includes a connecting rod. Both ends of the connecting rod are provided with clamping mechanisms. The clamping mechanism includes a support rod and a convex block. The top end of the support rod is fixedly connected to a fixed shell, and the convex block is slidably connected to the fixed shell.

[0008] Preferably, a fixing rod is fixedly connected to the surface of the machine tool worktable, a positioning groove is opened on the surface of the fixing base, and the fixing rod is inserted into the positioning groove. The support rod is fixedly connected to the connecting rod, and a first fixing pad is fixedly connected to the surface of the fixing shell. The fixing base is fixed to the surface of the machine tool worktable by inserting the fixing rod into the positioning groove.

[0009] Preferably, the fixed base is internally rotatably connected to a bidirectional screw, and the surface of the bidirectional screw is threaded with an adjusting block. The top of the adjusting block is fixedly connected to the connecting rod. By rotating the bidirectional screw, the two adjusting blocks drive the two connecting rods to move closer or further apart, improving the convenience of fixing or loosening the device's shaft.

[0010] Preferably, a sliding rod is slidably connected to the bottom end of the support rod, and the sliding rod is fixedly connected to the fixed base. A positioning plate is fixedly connected to the surface of the fixed shell. The bottom end of the support rod is fixed by the sliding rod, thereby improving the stability of the support rod in lateral sliding.

[0011] Preferably, the surface of the convex block is provided with equally spaced slots, and the center of the positioning plate is slidably connected with a rod, which is inserted into the adjacent slot. By inserting the rod into the slot, the position of the convex block and the fixed shell is fixed, preventing the convex block from sliding randomly.

[0012] Preferably, a protective cap is fixedly connected to the surface of the insertion rod, and a telescopic spring is fixedly connected inside the protective cap. One end of the telescopic spring is fixedly connected to the positioning plate. The telescopic spring provides tension to the protective cap, making the insertion rod and the slot more tightly connected.

[0013] Preferably, a scale is fixedly connected to the surface of the convex block, and the scale is slidably connected to the positioning plate. A second fixing pad is fixedly connected to the surface of the convex block. The scale is used to position the convex block and improve the accuracy of the convex block position adjustment.

[0014] This utility model provides a drilling and positioning device for automotive pins, which has the following advantages:

[0015] This automotive pin drilling and positioning device supports and fixes the pin through a support base, preventing deformation of the pin during drilling and improving drilling stability. Two connecting rods move closer together, driving a clamping mechanism to fix and hold the pin. A convex block slides inside the fixed housing, adjusting the clamping length of the pin. A support rod moves the fixed housing, bringing the convex block closer to the pin for clamping and fixing. A fixing rod inserts into the positioning groove, fixing the base to the machine tool table surface. When fixing pins of different diameters, simply replace the device with one of the appropriate size, reducing the difficulty of data adjustment and improving pin processing efficiency.

[0016] This automotive pin drilling and positioning device increases the friction between the fixing shell and the pin through a first fixing pad, improving the stability of the device in fixing the pin. The rotation of the bidirectional screw causes two adjusting blocks to move the two connecting rods closer or further apart, improving the convenience of fixing or loosening the pin. A sliding rod fixes the bottom end of the support rod, improving the stability of its lateral sliding. A positioning plate positions the insertion rod, which is then inserted into the slot to fix the position of the convex block and the fixing shell, preventing the convex block from sliding freely and improving the stability of the device in fixing the pin. A protective cap protects the telescopic spring from corrosion and damage caused by external impurities. The telescopic spring provides tension to the protective cap, ensuring a tighter fit between the insertion rod and the slot. A scale is used to position the convex block, improving the accuracy of its position adjustment. A second fixing pad increases the friction between the convex block and the pin surface.

[0025] This utility model provides a device for positioning and drilling holes in automotive pins.

[0026] Please see Figure 1 and Figure 2The device includes a machine tool worktable 1 and a fixed base 2. The surface of the fixed base 2 is fixedly connected with equidistantly arranged support bases 5. The surface of the machine tool worktable 1 is fixedly connected with a fixing rod 3. The surface of the fixed base 2 is provided with a positioning groove 4, and the fixing rod 3 is inserted into the positioning groove 4. By inserting the fixing rod 3 into the positioning groove 4, the fixed base 2 is fixed to the surface of the machine tool worktable 1. When it is necessary to fix pins of different diameters, the device of the corresponding size can be replaced, which reduces the difficulty of data adjustment and improves the processing efficiency of pins.

[0027] Please refer to it again. Figure 1 and Figure 3 A power mechanism 6 is provided in the middle of the fixed base 2. The power mechanism 6 includes a connecting rod 601. The pin is supported and fixed by the support base 5 to prevent the pin from deforming when drilling and to improve the stability of the pin drilling. The two connecting rods 601 move closer to each other to drive the clamping mechanism 7 to move and fix the pin.

[0028] Please refer to it again. Figure 1 , Figure 3 and Figure 4 Both ends of the connecting rod 601 are provided with clamping mechanisms 7. The clamping mechanism 7 includes a support rod 701 and a convex block 705. The top end of the support rod 701 is fixedly connected to a fixed shell 703, and the convex block 705 is slidably connected to the fixed shell 703. By sliding the convex block 705 inside the fixed shell 703, the clamping length of the pin is adjusted. The support rod 701 drives the fixed shell 703 to move, so that the convex block 705 and the fixed shell 703 are close to the pin to clamp and fix the pin.

[0029] The support rod 701 is fixedly connected to the connecting rod 601. A first fixing pad 704 is fixedly connected to the surface of the fixing shell 703, and a second fixing pad 706 is fixedly connected to the surface of the convex block 705. The first fixing pad 704 increases the friction between the fixing shell 703 and the pin, thereby improving the stability of the device in fixing the pin. The second fixing pad 706 increases the friction between the convex block 705 and the surface of the pin.

[0030] The fixed base 2 is internally rotatably connected to a bidirectional screw 602. An adjusting block 603 is threadedly connected to the surface of the bidirectional screw 602, and the top of the adjusting block 603 is fixedly connected to the connecting rod 601. A motor for controlling the rotation of the bidirectional screw 602 is fixedly connected to the surface of the fixed base 2. The motor is a mature device. This application can use existing power equipment that can drive the bidirectional screw 602 to rotate. By rotating the bidirectional screw 602, the two adjusting blocks 603 drive the two connecting rods 601 to move closer or further apart, thereby improving the convenience of fixing or loosening the device.

[0031] The bottom end of the support rod 701 is slidably connected to a sliding rod 702, and the sliding rod 702 is fixedly connected to the fixed base 2. The bottom end of the support rod 701 is fixed by the sliding rod 702, thereby improving the stability of the support rod 701 in lateral sliding.

[0032] A positioning plate 707 is fixedly connected to the surface of the fixed housing 703. The surface of the convex block 705 is provided with equally spaced slots 709. An insert rod 708 is slidably connected to the middle of the positioning plate 707, and the insert rod 708 is inserted into the adjacent slot 709. The positioning plate 707 positions the insert rod 708. The insert rod 708 is inserted into the slot 709 to fix the position of the convex block 705 and the fixed housing 703, preventing the convex block 705 from sliding randomly and improving the stability of the device's fixing pin.

[0033] A protective cap 711 is fixedly connected to the surface of the insertion rod 708. A telescopic spring 710 is fixedly connected inside the protective cap 711, and one end of the telescopic spring 710 is fixedly connected to the positioning plate 707. The protective cap 711 protects the telescopic spring 710 from corrosion and damage caused by external impurities. The telescopic spring 710 provides tension to the protective cap 711, making the insertion rod 708 and the slot 709 more tightly connected.

[0034] A scale 712 is fixedly connected to the surface of the convex block 705, and the scale 712 is slidably connected to the positioning plate 707. The scale value of the scale 712 is matched with the slot 709. The scale 712 is used to position the convex block 705, thereby improving the accuracy of the position adjustment of the convex block 705.

[0035] Working principle: When drilling the pin, select the appropriate positioning device, insert the fixing rod 3 into the positioning groove 4, and fix the fixing base 2 on the surface of the machine tool worktable 1. Pull the protective cap 711 outward to disengage the insertion rod 708 from the slot 709. Adjust the length of the convex block 705 laterally according to the length of the pin. After adjustment, release the protective cap 711, and the extension spring 710 provides tension to the protective cap 711, so that the insertion rod 708 is inserted into the slot 709. Adjust the position of the four convex blocks 705 according to the value of the scale 712, and then place the pin on the support base 5. On the surface, the bidirectional screw 602 is rotated by a motor, causing two adjusting blocks 603 to drive two connecting rods 601 to move closer to each other. The connecting rods 601 drive the support rod 701 to move, so that the convex block 705 and the fixed shell 703 drive the first fixing pad 704 and the second fixing pad 706 to fix and clamp the pin. With the above device, when it is necessary to position pins of different diameters, the corresponding device can be directly replaced, which reduces the difficulty of data adjustment when fixing the pin, improves the pin fixing efficiency, and the device can adjust the clamping length to meet the needs of fixing pins of different lengths, thus improving the practicality of the device.
