Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a feeding mechanism for an automatic bearing inner ring raceway ultra-precision machine. Background Technology

[0002] Ultraprecision machines are specialized equipment in the bearing industry, used to improve the surface roughness of bearing rolling elements, flanges, and other parts. Their working principle is as follows: the workpiece, driven by a pair of guide rollers on the machine tool, simultaneously rotates and moves axially linearly. An oilstone presses against the outer surface of the workpiece for axial machining, improving workpiece precision through micro-cutting. Existing flange-compound ultraprecision machines are inefficient, and bearing loading and support positioning operations are cumbersome, time-consuming, and labor-intensive.

[0003] The existing patent CN214519518U describes a fully automatic roller bearing inner ring raceway ultra-precision machine feeding mechanism, comprising a base, a feeding mechanism, and a support mechanism. A vertical plate is mounted on the rear edge of the upper end face of the base. The feeding mechanism is installed on one side of the upper part of the base, and the support mechanism is installed on the lower side of the feeding mechanism. The support mechanism includes a first rotating motor, the output shaft of which passes through the vertical plate and is connected to a locking block. A mounting base is sleeved on the outer side of the locking block. Workpiece fixing rods are mounted on the four outer end faces (top, bottom, left, right) of the mounting base. A side-blocking ultra-precision mechanism is mounted on the right side of the mounting base. A first vertical plate and a second vertical plate are sequentially mounted on the right side of the side-blocking ultra-precision mechanism. A second conveyor belt is mounted on the first and second vertical plates near the base end face. This invention can simultaneously complete workpiece feeding and workpiece positioning, with rapid, accurate, and reliable operation, and has advantages such as good performance.

[0004] However, in the process of using the above method, the bearing workpiece in the device needs to be conveyed by the first conveyor belt, adsorbed by the adsorption plate, and then moved laterally and longitudinally after adsorption. Finally, the workpiece fixing rod needs to be rotated and conveyed. This process is time-consuming, resulting in low processing efficiency of bearing workpieces. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for an automatic bearing inner ring raceway ultraprecision machine, which solves the problem that the feeding of bearing workpieces in the aforementioned device requires first passing through the first conveyor belt, then being adsorbed by the adsorption plate, and then moving laterally and longitudinally after adsorption, and finally requiring the rotation and transmission of the workpiece fixing rod. This process is time-consuming and results in low processing efficiency of bearing workpieces.

[0006] To achieve the above objectives, this utility model provides a feeding mechanism for an automatic bearing inner ring raceway ultraprecision machine, including a base and a feeding device. The feeding device includes a feeding slide, a discharging block, a feeding tray, a sleeve rod, a lever, a support assembly, and a connecting assembly. The feeding slide is mounted on the base via the support assembly and has a discharging port. The discharging block is rotatably mounted on the feeding slide via the connecting assembly and is close to the discharging port. The feeding tray is rotatably mounted on the base, the sleeve rod is fixedly mounted on the feeding tray, and the lever is fixedly mounted on the sleeve rod.

[0007] The support assembly includes a first support frame and a second support frame, both of which are fixedly installed on the base and respectively fixedly connected to both sides of the feeding chute.

[0008] The connecting assembly includes a connecting shaft, a connecting spring, and a connecting block. The connecting shaft is rotatably mounted on the feeding slide and fixedly connected to the unloading block. The connecting block is fixedly mounted on the unloading block. The two ends of the connecting spring are fixedly connected to the feeding slide and the connecting block, respectively.

[0009] The connecting assembly further includes a limiting rod, which is fixedly installed on the feeding slide and contacts the connecting block.

[0010] The feeding chute is also equipped with a baffle block, which is fixedly installed on the feeding chute and close to the discharge port.

[0011] This utility model discloses a feeding mechanism for an automatic bearing inner ring raceway ultraprecision machine. In use, bearing workpieces are placed sequentially on the feeding slide, allowing them to slide down one by one. The bottommost bearing workpiece enters the unloading port. An external motor then drives the feeding disc to rotate, which in turn causes the sleeve rod and the lever to rotate along the disc's axis. When the lever contacts the unloading block, it pushes the unloading block, causing it to rotate around the axis of the connecting shaft. At this time, the connecting spring elastically stretches. When the unloading block is misaligned with the unloading port, the bearing workpiece falls and is fitted onto the sleeve rod. At this time, the connecting spring uses its own elasticity to drive the connecting block and the unloading block to reset. The bearing workpiece on the sleeve rod is then brought to the right side of the base and processed by the ultra-precision machine on the right side of the base. Thus, through the cooperation of the loading slide, unloading block, loading plate, sleeve rod and lever, the bearing workpiece falls directly from the loading slide onto the sleeve rod on the loading plate and is transported to the processing, simplifying the loading process and thus speeding up the processing efficiency of the bearing workpiece.

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The embodiment of this application is as follows: Please see Figure 1-2 , Figure 1 This is a schematic diagram of the overall structure of the feeding mechanism of an automatic bearing inner ring raceway ultraprecision machine according to this utility model. Figure 2 This is a schematic diagram of the feeding device of this utility model.

[0018] This utility model provides a feeding mechanism for an automatic bearing inner ring raceway ultraprecision machine: it includes a base 101 and a feeding device, which includes a feeding slide 102, a discharging block 103, a feeding plate 104, a sleeve rod 105, a lever 106, a support assembly, and a connecting assembly. The support assembly includes a first support frame 108 and a second support frame 109. The connecting assembly includes a connecting shaft 110, a connecting spring 111, and a connecting block 112. The connecting assembly also includes a limiting rod 113. The feeding slide 102 is also provided with a stop block 114. The above solution solves the problem that in the above-mentioned device, the feeding of bearing workpieces requires first passing through the first conveyor belt, then the adsorption of the adsorption plate, and then the lateral and longitudinal movement after adsorption, and finally the rotation and transmission of the workpiece fixing rod. This process is time-consuming and results in low processing efficiency of bearing workpieces.

[0019] In this embodiment, through the cooperation of the loading slide 102, unloading block 103, loading plate 104, sleeve rod 105 and lever 106, the bearing workpiece is directly dropped from the loading slide 102 onto the sleeve rod 105 on the loading plate 104 and transported to the processing, which simplifies the loading process and speeds up the processing efficiency of the bearing workpiece.

[0020] The feeding slide 102 is mounted on the base 101 via the support assembly. The feeding slide 102 has a discharge port 107. The discharge block 103 is rotatably mounted on the feeding slide 102 via the connecting assembly, and is close to the discharge port 107. The feeding tray 104 is rotatably mounted on the base 101. The sleeve rod 105 is fixedly mounted on the feeding tray 104. The lever 106 is fixedly mounted on the sleeve rod 105. A baffle is provided on the side of the feeding slide 102. An ultra-precision machine is provided on the right side of the base 101 for processing bearing workpieces. The discharge block 103 is located directly below the discharge port 107 to prevent the bearing workpieces from falling. The feeding tray 104 is driven by an external motor. The sleeve rod 105... The number of 05 is in multiple groups and arranged in a ring on the upper surface of the feeding tray 104. The lever 106 has an L-shaped structure and is welded to the sleeve rod 105. The support assembly can support the feeding slide 102. The connecting assembly can realize the rotational engagement between the unloading block 103 and the feeding slide 102, and can drive the unloading block 103 to reset. Through the rotation of the feeding tray 104, the lever 106 on the sleeve rod 105 pushes the unloading block 103, causing the unloading block 103 to rotate away from the unloading port 107. The bearing workpiece falls directly onto the sleeve rod 105. As the sleeve rod 105 rotates to the ultra-precision machining position, the feeding process is simplified, thereby accelerating the processing efficiency of the bearing workpiece.

[0021] Secondly, the first support frame 108 and the second support frame 109 are both fixedly installed on the base 101 and are respectively fixedly connected to both sides of the feeding slide 102. The first support frame 108 is inclined, while the second support frame 109 is vertical. Through the cooperation of the first support frame 108 and the second support frame 109, the feeding slide 102 can be supported.

[0022] Secondly, the connecting shaft 110 is rotatably mounted on the feeding slide 102 and fixedly connected to the unloading block 103; the connecting block 112 is fixedly mounted on the unloading block 103; the two ends of the connecting spring 111 are fixedly connected to the feeding slide 102 and the connecting block 112 respectively; the connecting shaft 110 is rotatably engaged with the feeding slide 102 through a bearing; the connecting spring 111 is vertically arranged at the bottom of the feeding slide 102; and the connecting block 112 is welded to the side of the unloading block 103. Through the setting of the connecting shaft 110, the unloading block 103 and the feeding slide 102 are rotatably engaged, and the setting of the connecting spring 111 allows the connecting block 112 to drive the unloading block 103 to reset after the unloading block 103 rotates.

[0023] Furthermore, the limiting rod 113 is fixedly installed on the feeding slide 102 and contacts the connecting block 112. The limiting rod 113 is welded to the bottom of the feeding slide 102. By setting the limiting rod 113, the connecting block 112 after resetting can be restricted, so as to prevent the connecting block 112 and the unloading block 103 from shaking.

[0024] Finally, the baffle block 114 is fixedly installed on the loading slide 102 and close to the unloading port 107. The baffle block 114 is welded to the side of the unloading port 107. By setting the baffle block 114, the bearing workpiece can be prevented from rushing out of the unloading port 107.

[0025] In this embodiment, during use, bearing workpieces are placed sequentially on the loading slide 102, allowing them to slide down sequentially. The bottommost bearing workpiece enters the unloading port 107. An external motor then drives the loading disc 104 to rotate, which in turn drives the sleeve rod 105 and the lever 106 to rotate along the axis of the loading disc 104. When the lever 106 contacts the unloading block 103, it pushes the unloading block 103, causing it to rotate around the axis of the connecting shaft 110. At this time, the connecting spring 111 is elastically stretched. When the unloading block 103 and the connecting spring 111... After the discharge port 107 is misaligned, the bearing workpiece falls and is fitted onto the sleeve rod 105. At this time, the connecting spring 111 drives the connecting block 112 and the discharge block 103 to reset through its own elasticity. The bearing workpiece on the sleeve rod 105 is then brought to the right side of the base 101 and processed by the ultra-precision machine on the right side of the base 101. Thus, through the cooperation of the loading slide 102, the discharge block 103, the loading plate 104, the sleeve rod 105 and the lever 106, the bearing workpiece falls directly from the loading slide 102 onto the sleeve rod 105 on the loading plate 104 and is transported to the processing, simplifying the loading process and thus speeding up the processing efficiency of the bearing workpiece.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
