[0002] Synchronous belt guide is a device that converts the rotational motion of the motor into linear motion and is widely used in the automation industry. The components of synchronous belt guide include profile base, synchronous wheel, synchronous belt, guide rail and slider, etc. Most of these components belong to transmission parts. Its working principle is to drive the synchronous belt through the rotational motion of the internal motor, and then make the slider realize linear motion. Synchronous belt guide has the characteristics of high efficiency, low noise and high speed, and can provide the advantages of high design efficiency and convenient installation and debugging.

[0003] When processing the synchronous wheel, the opening in the middle position needs to be cut off from the workpiece in sequence by a very thin metal layer through a broaching device using a special broach, so that the surface can achieve higher dimensional accuracy and lower roughness.

[0016] Preferably, a processing method of a synchronous belt guide rail automatic processing device comprises the following steps:

[0017] Step 1: Place the workpiece in the middle of the clamping table, drive the second electric telescopic rod to extend, contact the workpiece through the pressure block, and clamp the workpiece to limit the position;

[0018] Step 2: The screw motor and the ball screw drive the second displacement slider to move downward, and the stepper motor is turned on. The stepper motor drives the tool changer to rotate, and moves the broach body to be installed to the lowest end;

[0019] Step 3: The cylinder extends forward, causing the first displacement slider to slide forward in the slide slot, driving the assembly seat and the assembly box to move closer to the tool changer, so that the assembly handle of the lowermost broach body is inserted into the assembly box;

[0022] Step 6: The driving motor drives the rotating table to rotate, and adjusts the processing position of the workpiece at the front clamping table so that the broaching tool body can perform broaching operation on another position of the workpiece.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) In the present invention, the broach body is assembled and combined through the broach assembly component, and the broach adjusting member drives the assembled and fixed broach body to perform forward and backward displacement operation, so that it can dock with the steering tool changing component for tool changing operation through displacement, and can also perform broaching operation with the workpiece at the clamping table. The steering tool changing component has a lifting function, which can conveniently adjust its tool changing height and avoid conflict with the broaching process. The overall tool changing process can be fully integrated into the broaching process, and the tool changing operation can be automatically performed without manual labor, thereby improving processing efficiency.

[0025] (2) In the present invention, when assembling with the assembly box, the assembly handle of the broach body is inserted into the cavity of the assembly box so that the first limit clamping hole is aligned with the second limit clamping hole, and then the clamping rod is extended by the first electric telescopic rod so that the clamping rod is inserted from the first limit clamping hole to the second limit clamping hole, so that the assembly handle of the broach body is fixed and restricted in the assembly box, thereby avoiding the situation where the broach is detached during the broaching displacement process. After the assembly handle is installed, the insertion part of the broach body is located outside the assembly box, so that it can perform the broaching process normally. When the broach body is placed on the tool changing station, its insertion part is inserted into the sleeve, and the size of the limit clamping ring is larger than the insertion part, so that it is restricted at the clamping ring assembly port, and is magnetically connected to the limit clamping ring through a magnetic ring, while the assembly handle is located outside the tool changing station, which is convenient for users to perform rapid tool changing operations by displacement docking at the assembly box.

[0026] (3) In the present invention, the gas is drawn from the fan to the extension duct, and the extension duct follows the broach into the workpiece. The waste chips generated during the broaching process are blown out by the gas in the extension duct, so as to avoid the waste chips being blocked inside the workpiece. The extension duct can also gather the wind force to generate a stronger blowing force and improve the blowing effect. During the broaching process, since there is space between the rotating table and the clamping table, when the fan blows, the waste chips generated during the broaching can be blown out to the outside of the workpiece, so that they finally fall into the collecting trough below, thereby achieving the effect of discharging the waste chips and collecting them in a centralized manner.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] See also Figure 1-8 An embodiment of the present invention is as follows: a synchronous belt guide rail automatic processing device comprises an equipment body 1, a broach adjusting member 2 is installed at one end above the equipment body 1, a broach assembly component 3 is installed above the broach adjusting member 2, a clamping rotating member 7 is installed at the other end above the equipment body 1, a collecting trough 9 is installed below the clamping rotating member 7, a steering tool changing assembly 6 is installed between the clamping rotating member 7 and the broach assembly component 3, lifting adjusting members 5 are arranged on both sides of the steering tool changing assembly 6, the broach assembly component 3 comprises an assembly box 306, a broach body 4 is inserted in the assembly box 306, and the broach body 4 comprises an inserting portion 4 01, an assembly handle 402 is provided at one end of the insertion part 401, a limit clamping ring 403 is provided between the assembly handle 402 and the insertion part 401, a second limit clamping hole 405 is provided on the outer wall of the assembly handle 402, a tool changing part 404 is detachably mounted on the front end of the insertion part 401 through bolts, a first limit clamping hole 303 is provided on the side wall of the assembly box 306, a first electric telescopic rod 301 is mounted on the side wall of the assembly box 306, a clamping rod 302 is installed at the telescopic end of the first electric telescopic rod 301, and one end of the limit clamping rod 302 is engaged with the second limit clamping hole 405 through the first limit clamping hole 303;

[0038] When assembling with the assembly box 306, the assembly handle 402 of the broach body 4 is inserted into the cavity of the assembly box 306, so that the first limit card hole 303 is aligned with the second limit card hole 405, and then the first electric telescopic rod 301 drives the clamping rod 302 to extend, so that the clamping rod 302 is inserted from the first limit card hole 303 to the second limit card hole 405, so that the assembly handle 402 of the broach body 4 is fixed and restricted in the assembly box 306, thereby avoiding the situation where the broach is detached during the broaching displacement process. After the assembly handle 402 is installed, the insertion part 401 of the broach body 4 is located outside the assembly box 306, so that it can carry out the broaching process normally, and the front end of the insertion part 401 can be replaced with a tool changing part 404 of different shapes and sizes by removing the bolts.

[0039] See also Figure 2 , Figure 3 The broach adjusting member 2 includes a broaching platform 205, both sides of the upper surface of the broaching platform 205 are provided with slide grooves 201, a first displacement slider 202 is installed inside the slide groove 201, an assembly seat 203 is installed above the first displacement slider 202, and an assembly box 306 is installed on the upper surface of the assembly seat 203 by bolts, and two groups of cylinders 204 are installed at the rear end of the assembly seat 203;

[0040] The assembly seat 203 is driven to move forward and backward by the cylinder 204, wherein the cylinder 204 is provided with two groups on the left and right. During the pushing process, the two groups of cylinders 204 extend forward at the same time, which can effectively increase the pushing force and make the pushing and displacement process smoother and more stable;

[0041] On the basis of the displacement driven by the above-mentioned cylinder 204, under the influence of the driving force, the first displacement slider 202 slides in the slide groove 201. The setting of the slide groove 201 and the first displacement slider 202 can prevent deviation during the displacement process, ensure the normal progress of subsequent tool change docking and workpiece processing, and can further improve the stability and smoothness of the displacement process. Based on the above-mentioned cylinder 204 driving displacement and slider displacement mode, the displacement tool change operation of the broach body 4 can be realized, and the broaching operation of the workpiece can also be realized.

[0042] See also Figure 6 , Figure 7The lifting and lowering adjusting member 5 includes a ball screw 501 on one side of the displacement, a screw motor 502 is installed at one end of the ball screw 501, and the lifting and lowering adjusting member 5 also includes a guide rod 503 installed on the other side, and a second displacement slider 504 is installed on the outer wall of the guide rod 503 and the ball screw 501. The steering tool changing assembly 6 includes an assembly frame 601 installed between the two second displacement sliders 504, a stepper motor 602 is installed on the outer wall of the assembly frame 601, and a tool changing platform 603 is installed at the output end of the stepper motor 602. A plurality of sleeves 605 are arranged at annular intervals on the outer wall of the tool changing platform 603, and a snap ring assembly port 604 is arranged at the front end of the sleeve 605, and a magnetic ring 606 is installed inside the snap ring assembly port 604;

[0043] The screw motor 502 and the ball screw 501 drive the second displacement slider 504 to move. During the displacement process, the assembly frame 601 is driven to move together, so that the height position of the tool changing platform 603 can be adjusted. When the tool needs to be changed, it is moved downward to facilitate the tool changing and assembly operation with the assembly box 306. When performing the broaching operation, the tool changing platform 603 is moved to the top through the drive of the screw motor 502 and the ball screw 501, so that it is no longer blocked between the broaching tool adjustment member 2 and the clamping rotating member 7, so that the subsequent broaching tool adjustment member 2 can drive the broaching tool body 4 to move forward and perform the broaching operation on the workpiece located at the clamping rotating member 7.

[0044] The stepper motor 602 is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. Through the characteristics of the stepper motor 602, the various tools installed at the tool changer 603 can be accurately adjusted to the tool change position at the lower end for tool change operation at the assembly box 306. The various tools are distributed in an annular interval, which is convenient for displacing different tools during the rotation process. Since the tool changer 603 is a truncated cone, and the tool is annularly spaced, its own tool storage capacity is improved, which is convenient for storing more tools for use in the subsequent broaching process.

[0045] When the broach body 4 is placed at the tool changing station 603, its insertion part 401 is inserted into the sleeve 605, and the size of the limit part snap ring 403 is larger than that of the insertion part 401, so that it is limited at the snap ring assembly port 604, and is magnetically connected to the limit part snap ring 403 through the magnetic ring 606, while the assembly handle 402 is located outside the tool changing station 603, so that the user can quickly change the tool by displacement docking at the assembly box 306;

[0046] During the subsequent tool changing process, since the assembly handle 402 is inserted into the assembly box 306 and is limited and fixed by the first electric telescopic rod 301, when the subsequent cylinder 204 pulls the handle backward, the magnetic ring 606 will be separated from the limiting part clamping ring 403, so that the limiting part clamping ring 403 is no longer restricted at the clamping ring assembly port 604, which makes it convenient to remove the insertion part 401 from the sleeve 605, thereby achieving the effect of tool change separation.

[0047] See also Figure 8 The clamping rotating member 7 includes a driving motor 701, a rotating table 702 is installed at the output end of the driving motor 701, a plurality of brackets 703 are installed at the front end of the rotating table 702, a clamping table 704 is installed at the front end of the bracket 703, three clamping parts 8 are installed at annular intervals on the outer wall of the clamping table 704, the clamping part 8 includes a positioning frame 803, a second electric telescopic rod 801 is installed above the positioning frame 803, and a pressure block 802 is installed at the telescopic end of the second electric telescopic rod 801.

[0048] See also Figure 2 , Figure 4 A fan 304 is installed at the rear end of the assembly box 306, and an extension air duct 305 is provided at the air outlet end of the fan 304, and the extension air duct 305 is located below the insertion portion 401; the fan 304 draws gas to the extension air duct 305, and the extension air duct 305 follows the broach into the workpiece, and the waste chips generated during the broaching process are blown out by the gas at the extension air duct 305 to avoid the waste chips being blocked inside the workpiece. The extension air duct 305 can also gather wind force to generate a stronger blowing force and improve the blowing effect.

[0049] The driving motor 701 is used to drive the rotating table 702 to rotate, and through the connection of the bracket 703, it drives the front clamping table 704 to rotate together, so that the workpiece clamped at the clamping table 704 can be turned, which is convenient for adjusting the broaching position. When clamping, the second electric telescopic rod 801 drives the pressure block 802 to extend forward and contact the workpiece, and the workpiece is clamped and positioned by applying pressure in three directions, thereby improving the stability of the workpiece during the processing, and the clamping operation can be adjusted according to the size of the workpiece; in addition, during the broaching process, since there is space between the rotating table 702 and the clamping table 704, when the fan 304 blows, the waste chips generated during broaching can be blown out to the outside of the workpiece, so that it finally falls into the collecting trough 9 below, thereby achieving the effect of discharging the waste chips and collecting them in a centralized manner. Among them, the driving motor 701 can also adopt a stepping type, which can more accurately drive the workpiece at the clamping table 704 to rotate to the required angle and orientation.

[0050] See also Figure 1-8 , a processing method of a synchronous belt guide rail automatic processing device, comprising the following steps:

[0051] Step 1: Place the workpiece at the middle position of the clamping table 704, drive the second electric telescopic rod 801 to extend, and contact the workpiece through the pressing block 802 to clamp and limit the workpiece;

[0052] Step 2: The screw motor 502 and the ball screw 501 drive the second displacement slider 504 to move downward, and the stepper motor 602 is turned on. The stepper motor 602 drives the tool changer 603 to rotate, and moves the broach body 4 to be installed to the lowermost end;

[0053] Step 3: The cylinder 204 extends forward, causing the first displacement slide block 202 to slide forward in the slide slot 201, driving the assembly seat 203 and the assembly box 306 to move closer to the tool changer 603, so that the assembly handle 402 of the lowermost broach body 4 is inserted into the assembly box 306;

[0054] Step 4: The first electric telescopic rod 301 extends forward, pushing the clamping rod 302 through the first limit clamping hole 303 and the second limit clamping hole 405, fixing the assembly handle 402 in the assembly box 306. After installation, the cylinder 204 drives the assembly box 306 to retract, and the insertion part 401 of the broach body 4 is pulled out of the sleeve 605, and the lifting adjustment member 5 drives the tool changer 603 to move upward and reset;

[0055] Step 5: The cylinder 204 extends forward again, pushing the assembled broach body 4 to the workpiece, and performs a reciprocating broaching operation on the workpiece by moving forward and backward. During the broaching process, the waste chips are blown forward by the fan 304 and the extended air duct 305, so that the waste chips fall from the rotating table 702 and the clamping table 704 into the collecting trough 9;

[0056] Step 6: The driving motor 701 drives the rotating table 702 to rotate, and adjusts the processing position of the workpiece at the front clamping table 704, so that the broaching tool body 4 can perform broaching operation on another position of the workpiece.

[0057] Based on the above steps, the device can firstly have a displacement function and can realize the most basic broaching operation on the workpiece. Secondly, the device can also improve its tool changing components through the forward and backward displacement function, so that the tool changing structure can fully match the feature of forward and backward displacement, and realize the tool changing process at the broaching tool assembly component 3 during the forward and backward displacement. The tool changing structure itself also has cutting and lifting functions, which are respectively used to switch different tool positions during the tool changing process and adjust the height of the tool during the tool changing process, thereby further improving the flexibility of the tool changing process. In addition, the workpiece position can be clamped and limited according to the size of the workpiece through the clamping rotating part 7, and during the broaching process, the angle of the workpiece can be changed according to different broaching tool hole positions, so that the broaching process can perform broaching operations on different positions of the workpiece, thereby improving the broaching efficiency.

[0058] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.

10. A processing method of a synchronous belt guide rail automatic processing device, which is implemented based on the synchronous belt guide rail automatic processing device according to claim 9, characterized in that: The following steps are involved: Step 1: placing the workpiece at the middle position of the clamping table (704), driving the second electric telescopic rod (801) to extend, contacting the workpiece through the pressing block (802), and clamping and limiting the workpiece; Step 2: The screw motor (502) and the ball screw (501) drive the second displacement slider (504) to move downward, and the stepper motor (602) is turned on. The stepper motor (602) drives the tool changer (603) to rotate, and moves the broach body (4) to be installed to the lowermost end; Step 3: The cylinder (204) extends forward, causing the first displacement slide block (202) to slide forward in the slide groove (201), driving the assembly seat (203) and the assembly box (306) to move closer to the tool changer (603), so that the assembly handle (402) of the lowermost broach body (4) is inserted into the assembly box (306); Step 4: The first electric telescopic rod (301) extends forward, pushing the clamping rod (302) through the first limit clamping hole (303) and the second limit clamping hole (405), fixing the assembly handle (402) in the assembly box (306). After installation, the cylinder (204) drives the assembly box (306) to retract, and the insertion part (401) of the broach body (4) is pulled out from the sleeve (605), and the lifting and adjusting member (5) drives the tool changing platform (603) to move upward and reset; Step 5: The cylinder (204) extends forward again to push the assembled broach body (4) to the workpiece, and performs a reciprocating broaching operation on the workpiece by moving forward and backward. During the broaching process, the waste chips are blown forward by the fan (304) and the extended air duct (305), so that the waste chips fall from the rotating table (702) and the clamping table (704) into the collecting trough (9); Step 6: The driving motor (701) drives the rotating table (702) to rotate, and adjusts the processing position of the workpiece at the front clamping table (704), so that the broaching tool body (4) can perform broaching operation on another position of the workpiece.
