Description

Technical Field

[0001] The present invention relates to the technical field of machine tool processing, and particularly relates to a special machine tool for broaching the clamping jaw stop of a chuck. Background Art

[0002] During the processing of traditional broaching machines, due to the large diameter of the workpiece to be processed, it cannot be processed in one go and needs to be processed repeatedly to achieve the best processing state. When processing repeatedly, manual clamping of the workpiece and replacement of the tool are usually required. This method not only has low efficiency, but also easily leads to operation errors, affecting the machining accuracy and the consistency of product quality. Especially when processing multiple different materials or requiring multiple different specifications of processing, manually adjusting and replacing the tool becomes the key factor restricting production efficiency.

[0003] In addition, traditional broaching machines often lack adjustment functions and are difficult to adapt to diverse processing requirements. For example, when machining the outer surface of different metal materials, they cannot automatically clamp the workpiece, cannot meet the clamping and processing of workpieces with different diameters, and need to replace the clamping components or make adjustments. These adjustments usually rely on the experience and technical level of the operator, which increases the uncertainty and complexity of production.

[0004] Therefore, the present invention provides a special machine tool for broaching the clamping jaw stop of a chuck to solve the above problems. Summary of the Invention

[0005] In view of the above situation, to overcome the deficiencies of the prior art, the present invention provides a special machine tool for broaching the clamping jaw stop of a chuck to solve the problems of automatically replacing the tool, meeting the processing of workpieces with different diameters, and being able to adaptively clamp the workpiece to ensure production efficiency.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: A special broaching machine for the chuck jaw stop, comprising a fixed box and a sliding box. A sliding plate is slidably connected to the inner wall of the fixed box. A reciprocating lead screw is rotatably connected to the inner side wall at one end of the fixed box. The sliding plate is threadedly connected to the outer wall of the reciprocating lead screw. A clamping cylinder is fixedly installed on the outer wall of the sliding plate. An installation plate is fixedly installed at the top of the other end of the fixed box. A replacement disc is rotatably connected to the outer wall of the installation plate. Knife holes are formed on the outer wall of the replacement disc, and the knife holes are matched with the clamping cylinder. A regulating shaft is rotatably connected to the inner wall of the installation plate. The regulating shaft is matched with the reciprocating lead screw and is drivingly connected to the replacement disc. One end of the sliding box is provided with a fixed plate, and a jacking cylinder is installed on the outer wall of the fixed plate. The jacking cylinder is opposite to the clamping cylinder. A liquid box is installed inside the sliding box, and the liquid box is matched with the knife holes. Through the setting of the clamping cylinder, this device can adaptively clamp workpieces with different diameters. After clamping, it can automatically perform broaching processing, so as to meet the processing of different workpieces. At the same time, after pulling the workpiece to complete the primary processing, it can automatically replace the tool to perform secondary deep processing, realizing the function of automatic processing at one time, avoiding the phenomenon of reduced processing efficiency caused by repeated processing multiple times, and avoiding the phenomenon of reduced replacement efficiency caused by manual tool replacement, and avoiding the phenomenon of replacement errors, etc.

[0007] Preferably, a driving motor is fixedly installed on the inner side wall at one end of the fixed box, and the output end of the driving motor is fixedly installed with a reciprocating lead screw.

[0008] Preferably, a cutting hole is formed on the inner wall of the installation plate. A fixed block is fixedly installed on the top of the installation plate. One end of the fixed block is fixedly installed with a connecting shaft, and friction lines are formed on the outer wall of the connecting shaft. The replacement disc is rotatably connected to the outer wall of the connecting shaft. Ring teeth are formed on the outer wall of the replacement disc along the circumference. The number of the knife holes is multiple, and tools are installed inside. The diameters of the knife holes are different. In the initial state of the replacement disc of this device, one of the knife holes is opposite to the cutting hole, and at this time the two are in a communicating state. At this time, the workpiece enters through the knife hole for cutting. At the same time, the friction lines formed on the outer wall of the connecting shaft of this device can prevent the replacement disc from shaking due to external forces or other reasons when the workpiece is not inserted, avoiding the phenomenon of misalignment between the knife hole and the cutting hole, and ensuring the smooth progress of the processing of this device.

[0009] Preferably, a clamping arc plate is slidably connected to the inside of the clamping cylinder. The number of the clamping arc plates is two, and the two clamping arc plates are arranged oppositely. A threaded block is fixedly installed on the outer wall of the clamping arc plate, and the threaded block is threadedly connected to the outer wall of a bidirectional lead screw. The bidirectional lead screw is rotatably connected to the outer wall of the sliding plate.

[0010] Preferably, a cross-shaped top plate is slidably connected inside the clamping arc plate, and a telescopic plate is slidably connected to the side wall of the cross-shaped top plate; a clamping gear is fixedly installed on the outer wall of the two-way lead screw, and the clamping gear is meshed with the abutting tooth plate. The abutting tooth plate is slidably connected inside the sliding plate. One end of the abutting tooth plate is fixedly installed and connected to one end of the abutting frame, and the other end of the abutting frame is connected to the cross-shaped top plate. A return spring is fixedly installed on the outer wall of the abutting frame, and the other end of the return spring is fixedly connected to the inner side wall of the sliding plate; when the device is in use, first insert the workpiece into the tool hole and the cutting hole. At the same time, in the initial state, the clamping cylinder of the device is opposite to the cutting hole. When the workpiece is inserted, it will enter the inside of the clamping cylinder at the same time. At this time, the cross-shaped top plate is forced to contract. At the same time, because the cross-shaped top plate is connected to the abutting frame, when the cross-shaped top plate is displaced, it will drive the abutting tooth plate to displace at this time. The abutting tooth plate drives the clamping gear to rotate, and the clamping gear drives the two-way lead screw to rotate, and the threaded blocks on its outer wall displace. The two clamping arc plates will displace towards each other to realize the clamping of the workpiece; the device can automatically clamp the workpiece through the two clamping arc plates, and the fixation is relatively firm, avoiding the phenomenon of falling off. The clamping arc plates of the device can be adapted to clamp workpieces of different sizes, and the greater the force of the workpiece against the top, the greater the clamping force of the clamping arc plates, ensuring the stability during the processing, avoiding the phenomenon of falling off or shaking during processing, and avoiding the phenomenon of deviation in workpiece processing. At the same time, the cross-shaped top plate of the device can increase the contact area, avoiding the phenomenon that the workpiece with a smaller diameter cannot be abutted. At the same time, the telescopic plate can contract, avoiding the phenomenon that the clamping arc plates cannot clamp, and automatically positioning the center of the circle after clamping, avoiding deviation.

[0011] Preferably, a fixed gear is fixedly installed on the outer wall of the reciprocating lead screw; a sliding cylinder is slidably connected to the outer wall of the adjusting shaft. One end of the sliding cylinder is installed with an adjusting cable through a bearing, and the other end of the adjusting cable is fixedly connected to the outer wall of the sliding plate. A tension spring is installed at the other end of the sliding cylinder, and the other end of the tension spring is connected to the outer wall of the connecting disk. The connecting disk is installed on the outer wall of the adjusting shaft. A sliding gear is fixedly installed on the outer wall of the sliding cylinder, and the sliding gear matches the fixed gear; a scroll spring is installed on the outer wall of the adjusting shaft, and the other end of the scroll spring is fixedly connected to the outer wall of the mounting plate. An adjusting gear is fixedly installed on the outer wall of one end of the adjusting shaft, and the adjusting gear is meshed with the ring gear; when the device is in processing, in order to facilitate step-by-step processing and avoid damage to the workpiece and the tool caused by excessive processing at one time, a tool with a larger tool hole is used at the initial stage of the device. When the sliding plate slides to the rearmost end, at this time, the adjusting cable will pull the sliding cylinder to displace, and the sliding gear will be engaged with the fixed gear. The fixed gear is in a continuous rotation state, which can ensure the engagement of the two. At this time, the rotation of the reciprocating lead screw will drive the sliding gear to rotate through the fixed gear. At this time, the tension spring is in a stretched state, so as to realize the rotation of the adjusting shaft driving the adjusting gear, and the adjusting gear drives the replacement disk to rotate by a fixed rotation angle. After the adjustment is completed, the reciprocating lead screw will synchronously drive the sliding plate to displace. At this time, the workpiece will be inserted into the tool hole. At the same time, the adjusting cable loses the tensile force. Under the action of the tension spring, the sliding gear resets. At this time, the scroll spring is still in a compressed state. The insertion of the workpiece into the tool hole will limit the reset reverse rotation of the adjusting shaft. After the workpiece is disassembled, the tool hole can be reset under the action of the scroll spring, which is convenient for reprocessing; the device can realize step-by-step processing, avoid damage to the workpiece or the tool caused by excessive processing at one time, realize primary rough processing and then fine processing. After the primary processing, the device can automatically replace the fine processing tool, complete the processing in one action, avoid the phenomenon of repeated replacement, improve the processing efficiency, and the tool replacement of the device can be linked with the processing. After processing one workpiece, the device can automatically reset the tool hole, so that continuous processing can be carried out.

[0012] Preferably, a compression disk is slidably connected inside the top extension cylinder. One end of the compression disk is fixedly installed with a compression spring, and the other end of the compression spring is fixedly connected to the other end of the top extension cylinder. A card slot is formed on the outer wall of the top extension cylinder, and the card slot communicates with the inside of the top extension cylinder. A clamping post is slidably connected to the side wall of the top extension cylinder. A clamping spring is fixedly installed on the outer wall of the clamping post, and the other end of the clamping spring is fixedly connected to the outer wall of the top extension cylinder. A roller is rotatably connected to the outer wall of the end of the clamping post located inside the top extension cylinder, and the number of rollers is multiple. When the device is initially used, first insert one end of the workpiece into the tool hole. At this time, insert the other end into the inside of the top extension cylinder through the card slot. At the same time, the clamping post clamps and fixes the side wall of the workpiece, and the compression disk extends the workpiece, so that the other end of the workpiece is inserted into the inside of the clamping cylinder. At this time, start the drive motor to drive the device for processing. The device can realize the function of automatic processing. At the same time, after the initial processing is completed, when the sliding plate moves to the rearmost end, that is, when it is close to the drive motor end, one end of the workpiece disengages from the top extension cylinder, and the workpiece slides on the outer wall of the roller. At this time, it is convenient to rotate the replacement disk to replace the tool hole without causing any influence.

[0013] Preferably, a slider is fixedly installed on the outer wall of the liquid tank. A driving gear is rotatably connected inside the slider. The outer wall of the driving gear is located outside the slider. The driving gear is fixedly installed on the outer wall of one end of the linkage shaft.

The sealing slide plate is matched with the eccentric wheel. A lower pressing plate is slidably connected inside the coolant tank. A lower pressing spring is fixedly installed on the top of the lower pressing plate. The top of the lower pressing spring is fixedly connected to the inner top wall of the coolant tank. Coolant is filled between the top of the sealing slide plate and the lower pressing plate. A spraying pipe is inserted into the coolant tank. One end of the spraying pipe is located inside the coolant. The other end of the spraying pipe is installed with a cooling arc plate. The cooling arc plate faces the outer wall of the replacement disc. When the device is in use, in order to avoid phenomena such as overheating during processing, when the sliding box is displaced, at this time the external teeth are meshed with the driving gear, and the liquid tank is connected to the mounting plate, the liquid tank will not be displaced. At this time, the driving gear drives the linkage shaft to rotate, so that the eccentric wheel abuts against the sealing slide plate, causing the sealing slide plate to squeeze the coolant above it, so that the coolant is sprayed out by the spraying pipe, realizing the cooling during the processing of the workpiece. Through the setting of the linkage shaft, the device can automatically start the coolant when starting, and can only be automatically started when processing workpieces, which can avoid the waste of coolant. At the same time, the sealing slide plate of the device squeezes the coolant to realize the pressurization function, and the lower pressing plate can make its bottom abut against the outer surface of the coolant, facilitating the pressurization function of the sealing slide plate.

[0015] 2. In the initial state of the replacement disc of the device, one of the tool holes is opposite to the cutting hole, and at this time the two are in a communicating state. At this time, the workpiece enters through the tool hole for cutting. At the same time, the friction lines provided on the outer wall of the connecting shaft of the device can prevent the replacement disc from shaking due to external forces or other effects when the workpiece is not inserted, avoiding the phenomenon of misalignment between the tool hole and the cutting hole, and ensuring the smooth progress of the processing of the device.

At the same time, in the initial state, the clamping cylinder 6 of the device is opposite to the cutting hole 508. When the workpiece is inserted, it will enter the inside of the clamping cylinder 6 at the same time. At this time, the cross-shaped abutting top plate 605 is stressed and contracts. At the same time, because the cross-shaped abutting top plate 605 is connected to the abutting frame 609, when the cross-shaped abutting top plate 605 is displaced, it will drive the abutting tooth plate 608 to displace at this time.

After the adjustment is completed, the reciprocating lead screw 10 will synchronously drive the sliding plate 3 to displace. At this time, the workpiece will be inserted into the tool hole 701. At the same time, the adjusting cable 502 loses the tensile force. Under the action of the tension spring 503, the sliding gear 505 resets. At this time, the scroll spring 506 is still in a compressed state. When the workpiece is inserted into the tool hole 701, it will limit the reset reverse rotation of the adjusting shaft 5.
