Description

Technical Field

[0001] This utility model belongs to the technical field of shaft inner hole processing equipment, and more specifically, it relates to a micro-hole processing inner hole correction device. Background Technology

[0002] A drilling machine is a general term for machinery and equipment that uses a tool harder and sharper than the target object to leave cylindrical holes or openings in the target object through rotary cutting or rotary extrusion. It is also called a drilling rig, hole punch, borer, or through-hole machine. During the drilling process, if the hole to be drilled is relatively fine with small tolerances, a correction device should be installed. While the shaft to be processed is being machined, a detection device should be used to correct any deviations in real time.

[0003] Currently, most domestically produced shaft processing equipment lacks a correction device, or the adjustment device is a temporary support, resulting in poor correction effect and relatively large processing errors. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a device for correcting the deviation of inner holes in micro-hole processing, which improves the correction effect and reduces processing errors.

[0005] This utility model discloses a micro-hole machining inner hole correction device, comprising a base plate; a pair of slide rails are provided at the upper end of the base plate; a base is provided inside the slide rails; a motor is fixedly connected to one side of the base; bearings are fixedly connected to both ends of the base; the inner rings of the two bearings are fixedly connected to a bidirectional lead screw; it also includes a pair of clamping blocks threadedly connected to the bidirectional lead screw; each clamping block has two sliding grooves; a slider is slidably connected inside each sliding groove on the same side; a support plate is fixedly connected between the two sliders; a pair of electric cylinders are embedded inside the base; the output ends of the two electric cylinders are fixedly connected to the support plate.

[0006] Preferably, each slide rail includes at least a slide track; each slide track is fixedly connected to the upper surface of the base plate; a second motor is fixedly connected to the inner side of each slide track; a lead screw is fixedly connected to the output end of each second motor; the end of each lead screw away from the second motor is rotatably connected to the slide track; a pair of moving blocks are fixedly connected to the base; each moving block is threadedly connected to the lead screw on the same side; and each second motor is a stepper motor.

[0007] Preferably, the lower ends of the two clamping blocks are provided with supports to enhance the support.

[0008] Preferably, the two clamping blocks are slidably connected to the base.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] (1) By setting up an electric cylinder and a support plate, the support plate is used to slightly lift the machining shaft to offset the error caused by its own weight, and the machining error of the inner hole of the shaft is adjusted in the longitudinal direction, thus realizing the correction of the inner hole machining; by setting up a motor, a clamping block and a two-way lead screw, the clamping block is used to hold the shaft to be machined, and the support plate is used to achieve stable support while improving the correction effect and reducing the machining error.

[0011] (2) By setting up slide rails, motor 2, and lead screw, when lateral deviation occurs, start motor 2 to make its output end rotate slowly and slightly adjust the lateral movement of the clamping block to counteract the lateral deviation of the shaft to be processed, thereby further improving the correction effect.

[0017] Specific Implementation Example 1: Please refer to... Figure 1-4A micro-hole machining inner hole correction device includes a base plate 10; a pair of slide rails 11 are provided on the upper end of the base plate 10; a base 12 is provided on the inner side of the slide rails 11; a motor 13 is fixedly connected to one side of the base 12; bearings 20 are fixedly connected to both ends of the base 12; the inner rings of the two bearings 20 are fixedly connected to a bidirectional lead screw 18; it also includes a pair of clamping blocks 14 threadedly connected to the bidirectional lead screw 18; each clamping block 14 has two sliding grooves 19; a slider 15 is slidably connected to the inner side of each sliding groove 19 on the same side; the two sliders 15 are fixedly connected to each other. A fixed connecting support plate 17 is provided; a pair of electric cylinders 16 are embedded inside the base 12; the output ends of the two electric cylinders 16 are fixedly connected to the support plate 17; by setting the electric cylinders 16 and the support plate 17, the support plate 17 is used to slightly lift the machining shaft to offset the error caused by its own weight, and adjust the machining error of the inner hole of the shaft in the longitudinal direction, thereby realizing the correction of the inner hole machining; by setting the motor 13, the clamping block 14, and the bidirectional lead screw 18, the clamping block 14 is used to clamp the shaft to be processed, and the support plate 17 is used to achieve stable clamping while improving the correction effect and reducing the machining error.

[0018] Please see Figure 3 Each slide rail 11 includes at least a slide track 1101; each slide track 1101 is fixedly connected to the upper end face of the base plate 10; a second motor 1102 is fixedly connected to the inner side of each slide track 1101; a lead screw 1103 is fixedly connected to the output end of each second motor 1102; one end of each lead screw 1103 away from the second motor 1102 is rotatably connected to the slide track 1101; a pair of moving blocks 21 are fixedly connected to the base 12; each moving block 21 is threadedly connected to the lead screw 1103 on the same side; each second motor 1102 is a stepper motor; by setting the slide track 1101, the second motor 1102, and the lead screw 1103, when a lateral deviation occurs, the second motor 1102 is started, causing its output end to rotate slowly, slightly adjusting the lateral movement of the clamping block 14 to counteract the lateral deviation of the shaft to be processed, thereby further improving the correction effect.

[0019] Please see Figure 1 Supports 22 are provided at the lower ends of the two clamping blocks 14 to strengthen the support.

[0020] Please see Figure 1 The two clamping blocks 14 are slidably connected to the base 12.

[0021] During operation, motor 13 is started, and the output end of motor 13 drives the double-acting lead screw 18 to rotate. During the rotation of the double-acting lead screw 18, the clamping block 14 clamps the shaft to be processed. Due to the influence of its own weight, the shaft to be processed may undergo a slight downward deformation when it is only clamped by the clamping block 14. At this time, the electric cylinder 16 is started to raise the support plate 17. The upper side of the support plate 17 abuts against the shaft to be processed, which counteracts the deformation of the shaft to be processed due to its own weight, and at the same time prevents the drill bit from being damaged due to the deformation of the shaft to be processed during the drilling process.

[0022] When a machining deviation occurs laterally, motor 1102 is started. The output of motor 1102 drives the lead screw 1103 to rotate, causing the clamping block 14 to slightly shift. After the drill bit passes through the correct drilling position, motor 1102 is reversed to reset the lead screw 1103, ensuring that subsequent machining of the drill bit continues according to the expected machining position. While clamping the workpiece, it effectively corrects errors during the machining process. The technical solution proposed in this application is a feasible implementation of the correction structure. In actual use, it still needs to be used in conjunction with a detection device installed at the drill bit or an external detection device to measure the required correction distance, thereby offsetting errors caused by material characteristics or insufficient support from existing equipment during machining. In actual machining, the device described in the technical solution proposed in this application can be installed in multiple locations, and the spacing and model of the multiple devices proposed in this application can be controlled according to the length and deformation characteristics of the shaft to be machined.
