[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] First, the present invention sets a workpiece base for carrying the ring-shaped part at the straightening station, and fixedly installs a straightening device at the center of the workpiece base. The straightening device is composed of a housing, a screw rod, a moving block, a guide member, a guide sleeve, a supporting block and a transmission rod. Among them, the screw rod is driven to rotate by an upper driving motor, driving the moving block to move up and down, and then synchronously pushing a plurality of guide members to slide radially through the transmission rod, so as to realize the uniform opening or closing of a plurality of supporting blocks along the radial direction. This device has a simple structure and a compact linkage, can perform multi-point synchronous internal support correction on the ring-shaped part, significantly improve the consistency of the roundness of the inner wall of the ring-shaped part, avoid the problems of local deformation and center offset caused by traditional manual knocking and single-point tightening, and ensure the machining accuracy and assembly quality.

[0039] Such as Figures 1-3As shown in the figure, on the one hand, the present application provides an automatic shaft collar calibration device, including a supporting and calibrating station 100 and a conveying station 200. Among them, the supporting and calibrating station 100 is provided with a workpiece base 110 for placing a ring-shaped part 300. A supporting and calibrating device is arranged on the workpiece base 110. The supporting and calibrating device includes a number of supporting blocks 121 and a screw 122 for driving the number of supporting blocks 121 to open or close. Above the supporting and calibrating station 100, a driving motor 130 is provided. The driving motor 130 is connected to the driving end of the screw 122 through a lifting mechanism. The conveying station 200 is equipped with a clamping assembly for picking and placing the ring-shaped part 300; the clamping assembly includes a lifting table 211. The lifting table 211 is provided with a guide plate 212 that can slide horizontally and a gear motor 213. A rack 214 that meshes with the output gear of the gear motor 213 is arranged on the guide plate 212. A fixture 215 for clamping the ring-shaped part 300 is arranged on the guide plate 212.

[0040] In a specific embodiment, a conveying station 200 is arranged in front of and behind the supporting and calibrating station 100. The upstream conveying station 200 is used to transport the ring-shaped part 300 to be supported and calibrated to the position to be picked up. The downstream conveying station 200 is used to take out the ring-shaped part 300 that has been supported and calibrated from the supporting and calibrating station 100 and transport it to the next process or for integrated collection. More specifically, the conveying station 200 includes a frame. A conveyor belt is arranged on the frame for transporting the ring-shaped part 300 to be supported and calibrated or the ring-shaped part 300 that has been supported and calibrated. A lifting motor is further arranged on the frame to drive the lifting table 211 to move up and down in the vertical direction. A guide rail is arranged on the lifting table 211, and the above-mentioned guide plate 212 is slidably arranged on the guide rail. A gear motor 213 is further arranged on the lifting table 211. A gear is arranged at its output end. After it is started, the gear rotates. The upper end surface of the above-mentioned guide plate 212 is horizontally provided with a rack 214. The gear of the gear motor 213 is horizontally placed and meshes with the teeth on the rack 214 of the guide plate 212. After the gear motor 213 is started, the guide plate 212 moves back and forth along the guide rail under the action of the gear. Specifically, it moves back and forth between the conveying station 200 and the supporting and calibrating station 100. Further, a fixture 215 for picking up the ring-shaped part 300 is fixedly arranged on the guide plate 212, such as a double-plate fixture 215 driven by a cylinder, which clamps the periphery of the ring-shaped part 300, and details are not described here. Under the coordination of the existing control system, the fixture 215 is configured to clamp the ring-shaped part 300 to be calibrated at the upstream conveying station 200. Through the movement and lifting actions of the guide plate 212, the ring-shaped part 300 is accurately placed on the workpiece base 110 of the supporting and calibrating station 100; after the supporting and calibration are completed, the ring-shaped part 300 is transferred from the supporting and calibrating station 100 to the downstream conveying station 200 through similar steps, realizing the full-automatic grasping, positioning, supporting and calibration, and transfer of shaft collar workpieces.

[0041] As Figures 2-3As shown in the figure, the support and calibration device includes a housing 123. A plurality of guide sleeves 124 are annularly and evenly distributed on the side wall of the housing 123, and the guide sleeves 124 extend along the radial direction of the housing 123. A guide member 125 is slidably disposed inside each of the plurality of guide sleeves 124. A moving block 127 is threadedly connected to the screw rod 122. It further includes a transmission rod 126. The two ends of the transmission rod 126 are respectively and rotatably connected to the moving block 127 and the guide member 125 in an up-and-down direction only. When the screw rod 122 rotates, the moving block 127 moves upward or downward along the screw rod 122, driving the guide member 125 to slide inward or outward in the guide sleeve 124, and further causing the support block 121 to contract or expand radially along the screw rod 122.

[0042] In one embodiment, the housing 123 is a hollow cylindrical structure, and a screw rod 122 is vertically disposed inside it. Connecting ears are vertically disposed at both ends of the transmission rod 126 and are hinged to the moving block 127 and the guide member 125. When the moving block 127 moves up and down, the transmission rod 126 can generate a pulling force or a pushing force on the guide member 125, driving the guide member 125 to slide inward or outward inside the guide sleeve 124. As an alternative embodiment, the guide sleeve 124 is a rectangular through groove, the guide member 125 is a rectangular body or a cylinder of a corresponding size, the inner side of the guide member 125 is provided with a hinge connected to the transmission rod 126, and a support block 121 is detachably fixed to the outer side. In the above structure, due to the cooperation between the guide member 125 and the guide sleeve 124, plus the vertically disposed connecting ears of the transmission rod 126, the rotation of the moving block 127, the transmission rod 126, and the guide member 125 around the screw rod 122 is restricted, eliminating the need to provide a guiding mechanism for the moving block 127, and the overall structure is simpler.

[0043] Further, as a preference, thread sections with opposite helix directions are respectively provided at the upper end and the lower end of the screw rod 122, and a moving block 127 is threadedly connected to each of the two thread ends. Since the helix directions of the upper and lower thread ends are opposite, when the screw rod 122 rotates, the upper and lower moving blocks 127 will approach or move away from each other, thereby simultaneously driving a plurality of transmission rods 126 connected thereto to move synchronously, causing each guide member 125 to contract inward or expand outward in the radial direction, and further realizing the synchronous opening and closing of a plurality of support blocks 121, completing the support and calibration or release action of the annular member 300, avoiding the stress concentration problem caused by the force transmission of a single moving block 127, effectively reducing the damage risk of the guiding assembly and the support block 121, improving the mechanical operation accuracy, and also extending the service life of the device.

[0044] In the above embodiment, a limiting portion 122a is provided in the middle of the screw rod 122. Thread segments with opposite helix directions are respectively provided on the upper and lower sides of the limiting portion 122a, and are respectively threadedly connected to the upper and lower moving blocks 127. On the basis of realizing bidirectional driving, this structure uses the limiting portion 122a as an intermediate barrier to ensure that the two moving blocks 127 only move axially on their respective independent thread segments, avoiding interference or deviation of the upper and lower moving blocks 127 due to excessive travel.

[0045] On the other hand, preferably, three guiding sleeves 124 are provided on the side wall of the housing 123. The three guiding sleeves 124 are arranged at intervals of 120° from each other on the same horizontal plane, and can form three-point balanced support for the annular member 300 during the correction process. A guiding member 125 is slidably disposed in each guiding sleeve 124, and a supporting block 121 is fixedly provided on the outer side of the guiding member 125, which is used to extend inwards or outwards under the drive of the moving block 127 to cooperate with the inner wall of the annular member 300 for radial tightening and correction. The three-point layout can effectively suppress the eccentricity risk brought by a single point or two points, make the forces at each point more uniform during the correction process, ensure that the geometric shape of the annular member 300 is accurately restored under the synchronous action of multiple points, and is beneficial to improving the correction accuracy and consistency. In addition, the three-point layout is also convenient for positioning the annular member 300, facilitating automatic identification and clamping.

[0046] As Figure 2 and Figure 4 shown, the supporting block 121 includes a connecting plate 121a and a circular supporting plate 121b. The inner side of the connecting plate 121a is detachably fixed to the outer side of the guiding member 125 by bolts. The circular supporting plate 121b is connected to the outer end of the connecting plate 121a, and the outer edge contour thereof is an arc surface structure. This arc surface can be attached to and tightened against the inner wall of the annular member 300 to achieve a uniform and stable supporting and correcting effect. Further, in order to enhance the connection stability between the connecting plate 121a and the guiding member 125 and the overall torsional stiffness, reinforcing plates 121c are respectively provided on both sides of the connecting plate 121a. The reinforcing plate 121c is preferably an L-shaped or triangular rib structure, which can resist the reaction force generated during the expansion of the circular supporting plate 121b, and improve the stability and durability of the connecting member under the stressed state.

[0047] As Figures 3-4 shown, an upper bracket 128 and a lower bracket 129 are respectively fixedly provided at the upper and lower ends of the housing 123. The screw rod 122 is rotatably connected to the upper bracket 128 and the lower bracket 129, and the driving end of the screw rod 122 extends to the upper end of the upper bracket 128.

[0048] In a specific embodiment, the upper bracket 128 and the lower bracket 129 are respectively provided with a bearing seat 128a, and the screw 122 is rotatably connected to the bearing seat 128a. Among them, the driving end of the screw 122 extends upward, passes through the upper bracket 128 and protrudes to its top, and is used to connect with the driving motor 130 arranged above the straightening station 100.

[0049] In a preferred embodiment, the cross-sections of the upper bracket 128 and the lower bracket 129 are Y-shaped, providing stable three-way support for the housing 123, and dispersing the mechanical stress received by the housing 123 when the screw 122 rotates or the guide member 125 expands and contracts. Further, the workpiece base 110 is provided with a fitting groove 111 that matches the shape of the lower bracket 129, so as to realize the limit assembly and stable positioning of the straightening device at the straightening station 100.

[0050] As Figures 4-5 shown, the workpiece base 110 is provided with a plurality of support columns 112. The support columns 112 are provided with installation grooves, and a supporting block 113 is hinged in the installation groove. The supporting block 113 includes a supporting portion 113a and a clamping portion 113b. The annular member 300 is placed on the supporting portion 113a, driving the supporting block 113 to rotate inward, and then the clamping portion 113b abuts against the side wall of the annular member 300.

[0051] In a specific embodiment, a torsion spring for driving the supporting block 113 to rotate outward is arranged at the hinge of the supporting block 113. A stop rod 114 for preventing the supporting block 113 from rotating outward excessively is arranged in the installation groove. The included angle between the supporting portion 113a and the clamping portion 113b is 90°. The clamping portion 113b is provided with a protrusion. Normally, the supporting block 113 flips outward under the action of the torsion spring and abuts against the stop rod 114, and the clamping portion 113b is in an open state. When the annular member 300 is placed in the supporting portion 113a of the supporting block 113, the supporting block 113 flips inward under the action of gravity, and the clamping portion 113b flips inward and abuts against the outer side wall of the annular member 300, realizing the clamping and fixing of the annular member 300. As a preference, three support columns 112 are arranged on the workpiece base 110 at equal intervals, realizing accurate centering while clamping and fixing. When taking out, just clamp the periphery of the annular member 300 with the above-mentioned fixture 215 and lift it upward, and the clamping portion 113b can be disengaged.

[0052] Based on the above shaft collar automatic correction equipment, this specification also provides a shaft collar automatic correction method, including the following steps:

[0053] Step 1: The clamping assembly grabs the annular part 300 to be calibrated at the conveying station 200; under the scheduling of the control system, the conveyor belt on the conveying station 200 conveys the annular part 300 to be calibrated to the designated grabbing position. At this time, the clamping assembly starts to perform the grabbing action. Specifically, the lifting table 211 descends vertically under the drive of the lifting motor, aligning the fixture 215 on the guide plate 212 with the annular part 300 to be calibrated.

[0054] Step 2: Drive the guide plate 212 to slide horizontally in the guide rail, moving the annular part 300 above the supporting and calibrating station 100; after the clamping assembly completes the clamping of the annular part 300, the control system drives the gear motor 213 arranged on the lifting table 211 to start. The gear output by the gear motor 213 meshes with the horizontal rack 214 arranged on the guide plate 212 and rotates, driving the guide plate 212 to move horizontally along the guide rail arranged on the lifting table 211. At this time, the annular part 300 is above the supporting and calibrating device, ready to complete the placement operation.

[0055] Step 3: Control the lifting table 211 to descend, placing the annular part 300 on the workpiece base 110. Under the action of gravity, the supporting block 113 rotates inwards, and the clamping part 113b clamps the annular part 300; with the fixture 215 maintaining the clamping state, the lifting motor drives the lifting table 211 to move downwards again, driving the guide plate 212 and the clamped annular part 300 to descend above the workpiece base 110. When the annular part 300 contacts the supporting block 113 on the workpiece base 110, continuing to descend will cause the annular part 300 to press the supporting part 113a of the supporting block 113 by gravity, prompting it to rotate inwards around the hinge point at the installation groove. At this time, the clamping part 113b on the supporting block 113 also rotates inwards accordingly and fits against the outer sidewall of the annular part 300, achieving automatic clamping and limiting.

[0056] Step 4: Drive the driving motor 130 to rotate the screw 122, driving the supporting blocks 121 to open and tightly calibrate the annular part 300; after confirming that the annular part 300 is stably placed, the control system starts the driving motor 130 arranged above the supporting and calibrating station 100. The driving motor 130 drives the screw 122 to rotate through a coupling. The screw 122 is threadedly connected to the moving block 127 inside the housing 123. The rotation of the screw 122 will drive the moving block 127 to move axially up and down. The moving block 127 applies a pushing and pulling force to the guiding member 125 through the transmission rod 126 hinged to it, thereby driving the guiding member 125 to slide along the guiding sleeve 124, causing the externally fixed supporting blocks 121 to open radially and tightly support the inner wall of the annular part 300 evenly.

[0057] Step Five: After the calibration is completed, drive the motor 130 to rotate in the reverse direction to contract the supporting block 121, re-clamp the annular part 300 with the clamping assembly, and move it to the next conveying station 200. After the calibration reaches the set duration or the sensor detects the target position, the control system issues an instruction to drive the motor 130 to rotate in the reverse direction, driving the screw rod 122 to rotate in the reverse direction, thereby causing the moving block 127 to move in the opposite direction. The moving block 127 pulls the guiding member 125 through the transmission rod 126, causing the supporting block 121 to retract synchronously in the radial direction, releasing the tightening effect on the annular part 300. At this time, the lifting table 211 rises again, the clamping assembly re-clamps the calibrated annular part 300, and drives the guide plate 212 to move horizontally along the guide rail to the downstream conveying station 200. Finally, the lifting table 211 descends, the fixture 215 is loosened, and the annular part 300 is placed at the downstream conveying position, completing a full-automatic calibration process and waiting to enter the next process or the collection area.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
