Description

Technical Field

[0001] This utility model relates to the field of positioning drilling technology, specifically a high-efficiency positioning drilling tool for automobile engine cylinder blocks. Background Technology

[0002] As the skeleton of the core power component, the cylinder block of an automobile engine involves drilling a variety of high-precision hole systems, such as crankshaft holes, camshaft holes, oil passage holes, water passage holes, and bolt mounting holes. Its structure is a complex box shape with uneven wall thickness and reinforcing ribs, which can easily cause problems such as vibration, deformation, and difficulty in chip removal during drilling.

[0003] When drilling a workpiece, the chips and fragments pressed down by the drill bit will accumulate on the top of the worktable. When the drill bit feeds downward, it will be obstructed and needs to overcome the squeezing and pushing resistance of the chips before entering the workpiece. This makes it impossible to accurately control the feed rate of the drill bit. If the feed rate is too shallow, drilling will not be possible. If the feed rate is too long, the drill bit will easily come into contact with the table surface, damaging the equipment and affecting the drilling effect.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing a high-efficiency positioning drilling tool for automobile engine cylinder blocks. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a high-efficiency positioning drilling fixture for automotive engine cylinder blocks, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a high-efficiency positioning drilling fixture for automobile engine cylinder blocks, including a machine body, a worktable fixed on the top of the machine body, a worktable for placing workpieces slidably connected on both sides of the top of the worktable, a clamping block for clamping function slidably provided on the top of the worktable, and a threaded rod rotatably connected to the bottom of the clamping block. By rotating the threaded rod, the distance between the two clamping blocks can be adjusted according to the size of the workpiece to effectively clamp the workpiece to be processed.

[0007] The top of the workbench is provided with multiple rotating rollers for crushing materials. A limit rod III is fixed on the top of the workbench. The rotating rollers are sleeved on the surface of the limit rod III through a connecting block. The connecting block and the limit rod III only contact each other but are not connected.

[0008] As a preferred embodiment of this utility model, the connecting block is disposed at both ends of the rotating roller and is rotatably connected to the rotating roller. The connecting block moves on the surface of the limiting rod III, and the two ends of the platform are slidably connected to the limiting rod I with limiting function.

[0009] As a preferred embodiment of this utility model, a sleeve block is fitted in the middle of the rotating roller, the number of sleeve blocks is equal to that of the rotating roller, the sleeve block is rotatably connected to the rotating roller, and the diameter of the collar at the top of the sleeve block is smaller than the diameter of the rotating roller, so that when there is no gap between each rotating roller, there will be no obstruction, and the residual debris adhering to the surface can be cleaned during rotational friction.

[0010] As a preferred technical solution of this utility model, a motor is installed inside the machine body, and a lead screw is installed at the drive end of the motor. With the motor as a reference, the sleeve farthest from the motor is threadedly connected to the lead screw, and the other sleeves are all sleeved on the surface of the lead screw, only in contact but not connected.

[0011] As a preferred technical solution of this utility model, the surface of the connecting block is rotatably connected to a hinge rod, and the surface of the sleeve block is penetrated by a limiting rod II for limiting the position. The limiting rod II is fixed inside the machine body. The screw rotates to push the sleeve block furthest from the motor to move, while simultaneously pulling the hinge rod to gradually approach a straight line state change, and simultaneously pushing other rotating rollers to move to adjust the spacing between each rotating roller.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By using rotating rollers, the accumulation of falling debris on the top of the machine body is prevented from affecting the drilling effect. The spacing between the rotating rollers can be adjusted according to the size of the debris generated by the drilling equipment through the setting of lead screw and hinge rod. When the hinge rod retracts, each rotating roller can make seamless contact with each other, and then each rotating roller rotates. During rotation, each rotating roller can rub against each other to clean the debris adhering to the surface of the rotating roller, so that the surface of the rotating roller always remains smooth and prevents excessive adhering debris from obstructing other debris from entering the machine body.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 As shown, a high-efficiency positioning drilling fixture for automobile engine cylinder blocks includes a body 1, a worktable 2 fixed on the top of the body 1, and a worktable 3 for placing workpieces slidably connected to both sides of the top of the worktable 2. A clamping block 301 for clamping is slidably provided on the top of the worktable 3. A threaded rod 303 is rotatably connected to the bottom of the clamping block 301. By rotating the threaded rod 303, the distance between the two clamping blocks 301 can be adjusted according to the size of the workpiece to effectively clamp the workpiece to be processed.

[0020] The top of the workbench 2 is provided with multiple rotating rollers 4 for crushing. A limit rod Ⅲ 406 is fixed on the top of the workbench 2. The rotating rollers 4 are sleeved on the surface of the limit rod Ⅲ 406 through a connecting block 402. The connecting block 402 and the limit rod Ⅲ 406 only contact each other but are not connected.

[0021] In one specific embodiment of this utility model, the connecting block 402 is disposed at both ends of the rotating roller 4 and is rotatably connected to the rotating roller 4. The connecting block 402 moves on the surface of the limiting rod Ⅲ 406, and the two ends of the platform 3 are slidably connected to the limiting rod Ⅰ 302 with limiting function.

[0022] In one specific embodiment of this utility model, a sleeve block 405 is fitted in the middle position of the rotating roller 4. The number of sleeve blocks 405 is equal to that of the rotating roller 4. The sleeve blocks 405 are rotatably connected to the rotating roller 4. The diameter of the collar at the top of the sleeve block 405 is smaller than the diameter of the rotating roller 4. This ensures that there is no obstruction when there is no gap between each rotating roller 4, and that the residual debris adhering to the surface can be cleaned during rotational friction.

[0023] In one specific embodiment of this utility model, a motor is installed inside the body 1, and a lead screw 403 is installed at the motor drive end. With the motor as a reference, the sleeve 405 farthest from the motor is threadedly connected to the lead screw 403, and the other sleeves 405 are all sleeved on the surface of the lead screw 403, only in contact but not connected.

[0024] In one specific embodiment of this utility model, a hinge rod 401 is rotatably connected to the surface of the connecting block 402, and a limiting rod II 404 for limiting is passed through the surface of the sleeve block 405. The limiting rod II 404 is fixed inside the machine body 1. The screw 403 rotates to push the sleeve block 405 furthest from the motor to move, while pulling the hinge rod 401 to gradually approach a straight state change, and at the same time pushing the other rotating rollers 4 to move and adjust the distance between each rotating roller 4.

[0025] When machining an automobile engine block, the distance between the two platforms 3 can be adjusted according to the size of the block. The block is then placed on top of the platform 3 and clamped and positioned by the clamping block 301. Material fragments from the stamped and sheared automobile engine block are discharged along the chip removal groove of the drill bit, forming chips located at the top of the machine body 1. The motor drives the lead screw 403 to rotate, causing the sleeve block 405 on the surface of the lead screw 403 to move the rotating roller 4 gradually away from the motor, thus opening the distance between each pair of adjacent rotating rollers 4. This allows the falling chips to fall through the open distance between the two rotating rollers 4. The debris falls into the equipment and is collected in a concentrated manner to prevent it from accumulating on the top of the machine body 1 and affecting the drilling effect. The spacing between the rotating rollers 4 can be adjusted according to the size of the debris generated by the drilling by the lead screw 403 and the hinge rod 401. When the hinge rod 401 retracts, each rotating roller 4 can make seamless contact with each other, and then each rotating roller 4 rotates. During rotation, each rotating roller 4 can rub against each other to clean the debris adhering to the surface of the rotating roller 4, so that the surface of the rotating roller 4 always remains smooth and to prevent excessive debris from hindering other debris from entering the machine body 1.
