Description

Technical Field

[0001] This utility model relates to the field of sprocket deburring technology, and in particular to an automatic sprocket deburring machine. Background Technology

[0002] A sprocket is a wheel with interlocking teeth used to mesh with precisely pitched blocks on a chain link or cable. Sprockets are widely used in mechanical transmissions in industries such as chemical engineering, textile machinery, escalators, woodworking, automated parking systems, agricultural machinery, food processing, instrumentation, and petroleum. The sprocket material must ensure sufficient strength and wear resistance for the teeth; therefore, sprocket teeth are generally heat-treated to achieve a certain hardness.

[0003] During the manufacturing process of sprockets, deburring devices are needed to repair the burrs on the sprocket teeth, thereby improving the sprocket's appearance and practicality.

[0004] In the sprocket manufacturing process, deburring is the final step and also the step with the least amount of processing work. However, in actual production, sprocket deburring is mostly done manually, one by one, which is labor-intensive, slow, increases production costs, and hinders capacity expansion. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. To overcome the aforementioned deficiencies of existing technologies, this utility model provides an automatic deburring machine for sprockets, aiming to solve the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides an automatic deburring machine for sprockets, comprising: a base, a fixing and limiting mechanism for fixing the sprocket is provided on the upper end surface of the base, and a processing mechanism for deburring the sprocket is provided on the upper end surface of the base. The fixing and limiting mechanism and the processing mechanism are symmetrically arranged about the longitudinal midline of the base, forming a dual-station structure.

[0007] The base design provides stable support for the entire device; this is common knowledge in the field and will not be elaborated further. In use, the sprocket to be processed is first fixed and limited by a fixing and limiting mechanism. After fixing, the sprocket is deburred by the processing mechanism. The dual-station simultaneous processing method greatly improves production efficiency. Furthermore, integrated sensors are installed during processing, allowing operators to adjust grinding parameters according to actual conditions, achieving adaptive grinding and further improving work efficiency and reducing labor intensity.

[0008] Preferably, the lower end face of the base is provided with a support leg, and two sets of the support legs are symmetrically arranged about the longitudinal midline of the base, and both sets of support legs are made of rubber.

[0009] The support legs are auxiliary components of the base, which help the base to fix and support the entire device. The rubber support legs increase the friction between the base and the external ground, thereby preventing the base from shifting during use.

[0010] Preferably, the fixed limiting mechanism includes a fixing fixture and a clamping part.

[0011] The fixing fixture is used to securely hold the sprocket to be processed, and the clamping part is used to clamp and limit the sprocket on the fixing fixture. The independent modular design of the fixing fixture and the clamping part not only allows for replacement according to the size of the sprocket, avoiding limitations for operators during use, but also facilitates subsequent maintenance procedures, demonstrating the practicality of this device.

[0012] Preferably, the fixing fixture has a cylindrical structure, and the top of the cylindrical fixing fixture has a pre-set annular protrusion.

[0013] The radius of the annular protrusion on the top of the fixing fixture is adapted to the radius of the cavity in the middle of the sprocket, thus allowing the sprocket to be placed using the fixing fixture. This design prevents wear on the sprocket surface when fixing and limiting the sprocket. Furthermore, a rotary motor is pre-installed inside the base, and the output shaft of the rotary motor is connected to the bottom of the fixing fixture via a coupling. This design allows the fixing fixture to rotate without affecting quick-change operation, thereby uniformly deburring each tooth on the sprocket.

[0014] Preferably, the clamping part includes a fixed base, a clamping cylinder, a connecting block, and a pressing block;

[0015] The fixing base is located on opposite sides of the two fixing fixtures, and bolt holes are pre-drilled on the fixing base;

[0016] The clamping cylinder is vertically mounted on top of the fixed base;

[0017] The connecting block is installed on the output shaft of the clamping cylinder, and one side of the connecting block is connected to the fixed seat to form a sliding structure;

[0018] The pressure block includes a connecting end and a pressing end. The connecting end of the pressure block is arranged parallel to the connecting block, and the pressing end of the pressure block has a cylindrical structure and is located on the lower end face of the connecting end of the pressure block away from the connecting block.

[0019] The fixed seat serves as a support for the clamping cylinder. The clamping cylinder employs a structure already available in the market and is used to drive the connecting block to move longitudinally up and down along the surface of the fixed seat, thereby causing the pressure block to move up and down. A slider and slide rail are pre-installed between the connecting block and the fixed seat, which limit the movement of the pressure block, ensuring that the pressure block always remains within a preset path.

[0020] Preferably, the processing mechanism includes a chip removal section and a grinding section.

[0021] During the deburring process of the sprocket, the chip removal section first removes the waste chips from the surface of the sprocket, and then the grinding section deburrs the sprocket. The chip removal section and the grinding section adopt an independent modular design, which facilitates the maintenance process of the staff later.

[0022] Preferably, the chip removal part includes a support base, a lifting cylinder, a connecting member, and a scraper;

[0023] The support base is located on the opposite sides of the two fixed fixtures, and bolt holes are pre-drilled on the support base;

[0024] The lifting cylinder is vertically mounted on top of the support base;

[0025] The connector is installed on the output shaft of the lifting cylinder, and one side of the connector is connected to the support base to form a sliding structure;

[0026] The scraper is positioned parallel to the outer surface of the connector on the side away from the support.

[0027] The support base is used to fix and install the lifting cylinder. The lifting cylinder adopts a structure already available in the market in this field, and is used to drive the connecting part to move vertically up and down along the support base, thereby driving the scraper to move up and down. A slider and slide rail are preset between the connecting part and the support base, which limit the movement of the scraper and ensure that the scraper always moves along the preset path.

[0028] Preferably, the grinding unit includes a grinding motor and an angle grinding disc;

[0029] The grinding motor is vertically mounted on the base via a multi-servo lead screw module;

[0030] The angle grinding disc is mounted on the output shaft of the grinding motor.

[0031] The grinding motor adopts a commercially available structure to drive the angle grinding disc to rotate and deburr the sprocket surface. During use, the position of the grinding motor can be adjusted via a multi-servo screw module according to actual needs. The use of PCL automatic control technology combined with the multi-servo screw module design achieves high-precision processing, ensuring the stability and consistency of product quality.

[0032] Preferably, the multi-servo lead screw module includes a horizontal axis base plate, a mounting base, a horizontal axis cylinder, a vertical axis mounting bracket, a mounting plate, a servo motor, a lead screw, a positioning block, and an angle swing bracket;

[0033] The horizontal shaft base plate is installed on the upper end face of the base and is located behind the fixed fixture;

[0034] The mounting base is located on the upper end face of the horizontal shaft base plate, and the mounting base and the horizontal shaft base plate are slidably connected.

[0035] The horizontal shaft cylinder is located on the rear side of the horizontal shaft base plate, and its output shaft is connected to the rear end face of the mounting base.

[0036] The vertical shaft mounting bracket is located on the upper end face of the mounting base;

[0037] The mounting plate is positioned on the side of the vertical shaft mounting bracket closest to the fixed fixture;

[0038] The servo motor is located at the top of the mounting plate;

[0039] The lead screw is vertically mounted on the mounting plate, and is connected to the output shaft of the servo motor at the top of the lead screw, with its end movably connected to the mounting plate;

[0040] The positioning block is installed on the lead screw, and the positioning block includes a threaded end and a positioning end. The threaded end of the positioning block is sleeved on the lead screw and is threadedly connected to the lead screw. The positioning end of the positioning block is semi-enclosedly installed on the threaded end and is slidably connected to the mounting plate.

[0041] The angle swing bracket is located on the side of the positioning block away from the mounting plate, and the angle swing bracket is connected to the rear end face of the grinding motor.

[0042] The horizontal axis base plate provides fixed support for the multi-servo lead screw module and mounts it at a designated position on the base. A slider and slide rail are pre-installed between the mounting base and the horizontal axis base plate, forming a sliding structure. The horizontal cylinder uses a commercially available structure to drive the mounting base to move laterally back and forth along the top of the horizontal axis base plate. The vertical axis mounting bracket is used to mount the mounting plate above the mounting base. The mounting plate is used to fix the servo motor and lead screw. During use, the servo motor drives the lead screw to rotate in both directions, causing the positioning block to move longitudinally up and down parallel along the threads on the lead screw via an angle swing bracket that drives the grinding motor. The angle swing bracket uses a commercially available movable bracket to adjust the angle between the servo motor and the positioning block according to actual needs, thereby avoiding dead angles during the deburring of the sprocket.

[0043] Preferably, it also includes a centrifugal fan, which is located behind the support base, and two centrifugal fans are symmetrically arranged about the longitudinal midline of the base.

[0044] Two centrifugal fans are installed in two corresponding processing stations, and both centrifugal fans adopt existing structures in the field.

Furthermore, during the processing, integrated sensors are installed, allowing workers to adjust grinding parameters according to actual conditions, achieving adaptive grinding, which further enhances work efficiency and reduces labor intensity, thus facilitating its widespread use.

[0065] In this embodiment:

[0066] First, move the base 1 to the designated position, and use the support legs 101 to fix and support the entire device, and connect it to the external electrical control box.

[0067] Secondly, the two sprockets to be processed are placed on the fixed fixture 2 of the two processing stations at the same time, and the clamping cylinder 302 is activated, so that the clamping cylinder 302 drives the connecting block 303 to move downward along the surface of the fixed seat 301, thereby driving the pressure block 304 to move downward until the lower end face of the pressure block 304 is in contact with the upper end face of the sprocket, so that the clamping part 3 clamps and limits the sprocket.

[0068] Next, the lifting cylinder 402 is activated, causing the lifting cylinder 402 to drive the connecting piece 403 to move downward along the support base 401, thereby driving the scraper 404 to move downward.

During the movement, the mounting plate 605 is moved forward through the vertical axis mounting bracket 604. After the mounting plate 605 moves to the designated position, the servo motor 606 is started, causing the servo motor 606 to drive the screw 607 to rotate, thereby causing the positioning block 608 to move downward along the thread on the screw 607 through the angle swing bracket 609 to drive the grinding motor 501 to move downward.

[0070] Then, when the grinding motor 501 moves to the designated height, the grinding motor 501 is started, which drives the angle grinding disc 502 to rotate.
