Abstract
Description
Technical Field
[0001] This utility model relates to the field of drilling device technology, specifically to a drilling mechanism for piston pin machining. Background Technology
[0002] In the drilling process, piston pins are manually clamped and fixed before drilling with a drilling machine, which is inefficient. To address this, some companies directly clamp the piston pin in the groove of a turntable. The rotation of the turntable moves the piston pin to the required position, and then clamps and fixes it. The drawback is that manual unloading is required, and the efficiency needs to be improved. Utility Model Content
[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:
[0004] This application discloses a piston pin machining drilling mechanism, including a base. A turntable, a drilling assembly, and a drive mechanism are arranged inside the cavity of the base. The drive mechanism drives the turntable to rotate. Multiple slots for fixing piston pins are spaced apart on the peripheral wall of the turntable. The drilling assembly includes a seat, a first lifting mechanism, a second lifting mechanism, a drilling machine, a guide plate, a first telescopic mechanism, a second telescopic mechanism, and pressure blocks. The seat is located at the moving end of the first lifting mechanism, and the second lifting mechanism is mounted on the seat. The drilling machine is located at the moving end of the second lifting mechanism. The second telescopic mechanism is located on both sides of the seat wall of the drilling machine, and pressure blocks are located at the moving ends of the second telescopic mechanism. The two sets of second telescopic mechanisms move the pressure blocks towards each other to clamp the piston pin at the turntable slots. The first telescopic mechanism is located on one side of the first lifting mechanism, and the moving end of the first telescopic mechanism is connected to the guide plate. The first telescopic mechanism moves the guide plate, positioning the end of the guide plate between the two pressure blocks.
[0005] In use, if the piston pin is locked in the slot, after the turntable rotates to the predetermined position, the lifting mechanism 1 moves the seat upward, so that the predetermined slot is between the two telescopic mechanisms 2. The two telescopic mechanisms 2 move the pressure block to clamp the piston pin at the slot. Then, the lifting mechanism 2 moves the drilling machine upward, and the drilling machine drills the piston pin after it is clamped and fixed. After drilling is completed, the lifting mechanism 1 moves downward and the lifting mechanism 2 moves downward, so that the piston pin is released from the slot. The telescopic mechanism 1 moves the guide plate so that the end of the guide plate is on the path of the piston pin moving downward. The telescopic mechanism 2 retracts to release the clamping of the piston pin. The piston pin falls on the guide plate and slides down along the guide plate. The automation level of drilling and unloading is improved, and the efficiency is increased.
[0006] Furthermore, the base is trough-shaped with a drive mechanism installed on one side of the trough wall. The output end of the drive mechanism is connected to the turntable, which is a reasonable layout and facilitates assembly.
[0007] Furthermore, the seat is frame-shaped, and a lifting mechanism is provided on the bottom wall inside the frame. The frame structure facilitates the installation and fixation of the lifting mechanism.
[0008] Furthermore, a weight-reducing groove is provided on the peripheral wall of the turntable between adjacent slots, which helps to reduce the weight of the turntable.
[0009] Furthermore, a bracket is provided at the movable end of the telescopic mechanism and the bracket is slidably connected to the base. A guide plate is provided at the top of the bracket, which can predetermine the length of the bracket and thus position the guide plate in a suitable position.
[0010] Furthermore, the turntable is positioned above the drilling machine for easy drilling.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. The design of the drilling mechanism in this utility model improves the automation of drilling and material feeding, thus increasing efficiency. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] Example 1
[0021] like Figure 1 , Figure 2 , Figure 3 As shown, in this example, the piston pin machining drilling mechanism includes a base 1. If the base 1 is in the shape of a groove, a turntable 7 is installed in the groove cavity of the base 1. If the central axis of the turntable is pivotally connected to the groove walls on both sides, the driving mechanism 13 is a drive motor. The drive motor is fixed at the outer wall of the groove of the base, and the output end of the drive motor is connected to the central axis of the turntable to drive the turntable to rotate.
[0022] Multiple arc-shaped slots 8 are formed circumferentially along the peripheral wall of the turntable 7. When the piston pin is fed, it is directly fixed in the slot. In order to reduce weight, arc-shaped grooves, i.e. weight reduction holes 9, can also be formed between adjacent slots 8.
[0023] A drilling assembly is installed in the base cavity below the turntable 7. The drilling assembly includes a base 3, a lifting mechanism 1 2, a lifting mechanism 2 4, a drilling machine 5, a guide plate 11, a telescopic mechanism 1 10, a telescopic mechanism 2 14, and a pressure block 6. The lifting mechanism 1 2 is fixed to the bottom wall of the groove below the turntable 7. The lifting mechanism 1 2 is arranged longitudinally and the base 3 is fixed at its moving end. The lifting mechanism 1 is commonly a telescopic cylinder or a screw lifting mechanism.
[0024] The base 3 is shaped like a groove. A second lifting mechanism 4 is longitudinally fixed within the groove of the base 3. This second lifting mechanism is similar to a telescopic hydraulic cylinder. A drilling machine 5 is longitudinally mounted at the moving end of the second lifting mechanism 4. The drilling machine can be purchased directly from the market. A second telescopic mechanism 14 is horizontally installed on the groove walls of the base 3 on both sides of the drilling machine 5. This second telescopic mechanism is similar to a common telescopic cylinder. A pressure block 6 is installed at the moving end of the second telescopic mechanism 14. The end of the pressure block 6 is tapered, allowing it to better enter the end hole of the piston pin. When the turntable rotates to the slot, the piston pin is between the two pressure blocks. The two sets of second telescopic mechanisms move the pressure blocks in opposite directions to clamp the piston pin at the turntable slot. The tapered end of the pressure block then simultaneously positions the piston pin as it enters the end hole of the piston pin. Afterward, the second lifting mechanism starts the upward-moving drilling machine to drill the clamped piston pin.
[0025] In this example, a telescopic mechanism 10 is installed on one side of the lifting mechanism 2, such as... Figure 1 As shown, a telescopic mechanism 10 is horizontally installed on the right side of the lifting mechanism 2. A bracket 12 is fixed longitudinally at the moving end of the telescopic mechanism 10. The bracket 12 is slidably connected to the bottom wall of the base 1 groove. The top of the bracket 12 is connected to the guide plate 11. The guide plate 11 is as follows: Figure 1 As shown in the inclined upward configuration, when in use, if the lifting mechanism moves to the predetermined position, the telescopic mechanism one moves the guide plate and places the end of the guide plate below the piston pin held by the two pressure blocks. The telescopic mechanism two retracts to hold the pressure blocks holding the piston pin, and then the piston pin falls on the guide plate and slides down the guide plate to the desired position under its own weight.
[0026] In use, if the piston pin is locked in the slot, after the turntable rotates to the predetermined position, the lifting mechanism 1 moves the seat upward, so that the predetermined slot is between the two telescopic mechanisms 2. The two telescopic mechanisms 2 move the pressure block to clamp the piston pin at the slot. Then, the lifting mechanism 2 moves the drilling machine upward, and the drilling machine drills the piston pin after it is clamped and fixed. After drilling is completed, the lifting mechanism 1 moves downward and the lifting mechanism 2 moves downward, so that the piston pin is released from the slot. The telescopic mechanism 1 moves the guide plate so that the end of the guide plate is on the path of the piston pin moving downward. The telescopic mechanism 2 retracts to release the clamping of the piston pin. The piston pin falls on the guide plate and slides down along the guide plate. The automation level of drilling and unloading is improved, and the efficiency is increased.
[0027] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
