Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing measurement technology, and more specifically, it relates to a device for preventing scratches on the outer diameter of bearing rings in an automatic bearing outer diameter measuring instrument feeding machine. Background Technology
[0002] During the measurement of bearing outer diameter, the automatic feeding of bearings is often achieved by moving the feeding pallet up and down and pushing the feeding machine backing plate. In order to avoid the bearing being scratched by the feeding machine backing plate when the feeding pallet moves up and down, positioning support columns are usually used to position the bearing. By controlling the spacing of the positioning support columns, the bearing is kept at a certain distance from the feeding machine backing plate, thus preventing the bearing outer diameter from being scratched when the feeding pallet moves up and down.
[0003] For example, existing application number CN202323208887.7 discloses a bearing measurement and feeding mechanism, including a measuring platform and a fixed frame and a fixed bracket mounted on the measuring platform. A feeding plate is mounted on the fixed bracket via a cylinder. A screw is rotatably mounted inside the fixed frame. A drive motor connected to the screw is located outside the fixed frame. A nut is threaded onto the screw via a limiting mechanism. A connecting frame is mounted on the nut via an insertion mechanism. Extrusion grooves are provided on both outer walls of the connecting frame. Limiting blocks are provided in the extrusion grooves via an extrusion mechanism. Limiting openings are provided on both outer walls of the fixed frame. A movable frame is mounted on the connecting frame. This utility model, by setting up components such as a cylinder, feeding plate, screw, nut, connecting frame, movable frame, and stacking cylinder, allows the device to stack a large number of bearings to be tested and automatically complete the pushing and feeding operations, ensuring the convenience of bearing measurement, optimizing the structure of the bearing measuring device, and improving the functionality of the device.
[0004] Based on the above, in practical applications, existing anti-bearing ring outer diameter scratch devices often require operators to adjust multiple positioning supports one by one when adjusting the distance between the positioning supports and the feeding plate. This not only increases the frequency of repetitive work for operators and affects the parallelism between the positioning supports, but also easily causes the bearing ring axis to tilt during movement due to differences in the spacing between the positioning supports. This results in uneven contact force between the bearing ring and the positioning supports, causing localized increased wear and even jamming. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a bearing outer diameter scratch prevention device for an automatic bearing outer diameter measuring instrument feeding machine. This solves the problem that existing bearing outer diameter scratch prevention devices, in practical applications, often require operators to adjust multiple positioning supports one by one when adjusting the distance between the positioning supports and the feeding plate. This not only increases the frequency of repetitive work for operators and affects the parallelism between the positioning supports, but also easily leads to the bearing ring axis tilting during movement due to differences in the spacing between the positioning supports. This results in uneven contact force between the bearing ring and the positioning supports, causing localized increased wear and even jamming.
[0006] The purpose and effectiveness of this utility model's automatic bearing outer diameter measuring instrument and the bearing ring outer diameter anti-scratching device for the feeding machine are achieved by the following specific technical means:
[0007] An automatic bearing outer diameter measuring instrument feeding machine includes a bearing ring outer diameter scratch prevention device, comprising a support frame, a limiting guide plate, a feeding auxiliary mechanism, a material support plate, positioning pillars, and a spacing adjustment mechanism. The limiting guide plate is slidably mounted on the upper end of the support frame. The feeding auxiliary mechanism is located on the outer side of the lower end of the limiting guide plate. The feeding auxiliary mechanism includes two drive screws, which are rotatably connected to the left and right ends of the support frame, respectively. The material support plate is located above the limiting guide plate, and its left and right end faces are slidably connected to the support frame using resistance-increasing frames. The two resistance-increasing frames have a convex structure. Multiple positioning pillars are evenly arranged and slidably mounted on the upper end of the material support plate. The spacing adjustment mechanism is located on the bottom end face of the positioning pillars. The spacing adjustment mechanism includes multiple adjusting screws, which are vertically rotatably mounted on the outer side of the bottom end face of the multiple positioning pillars.
[0008] Furthermore, two electric push rods are fixedly connected to the upper side of the rear end of the support frame using a T-shaped connecting frame; a connecting plate is fixedly connected to the outer side of the piston rod at the front end of the electric push rod; multiple push plates are evenly arranged and fixedly connected to the front end face of the connecting plate; the push plates have a V-shaped frame structure.
[0009] Furthermore, the feeding auxiliary mechanism also includes a drive shaft and a bevel gear transmission assembly. The drive shaft is vertically rotatably disposed on the outside of the left-end drive screw, and the outer end of the drive shaft is coaxially fixedly connected to the outside of the drive motor shaft. The bevel gear transmission assembly is disposed between the left-end drive screw and the drive shaft.
[0010] Furthermore, the left and right sides of the material support plate are threaded with adjusting screws, and the bottom end face of the adjusting screws abuts against the limiting guide plate to maintain a suitable distance between the material support plate and the limiting guide plate.
[0011] Furthermore, the spacing adjustment mechanism also includes: an adjustment support shaft and adjustment auxiliary blocks. The adjustment support shaft is rotatably connected to the outer side of the lower end of the limiting guide plate. There are multiple adjustment auxiliary blocks, which are respectively fixedly connected to the outer side of the bottom end face of multiple positioning supports. The adjustment auxiliary blocks on the same side are threadedly connected to the adjustment screw. A drive worm gear is coaxially fixedly connected to the outer end of the adjustment screw. A drive worm is provided on the outer side of the drive worm gear, and the drive worm meshes with the drive worm gear. Multiple drive worms are coaxially fixedly connected to the adjustment support shaft.
[0012] Furthermore, multiple positioning auxiliary frames are arranged circumferentially at the outer end of the positioning support column, and the positioning auxiliary frames are arc-shaped frame structures; multiple elastic tensioning members are arranged vertically and fixedly connected between the positioning auxiliary frames and the positioning support column.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In use, this utility model enables adjustment of the distance between the positioning support and the push plate, reducing the frequency of repetitive work for operators, improving the adjustment efficiency of the positioning support, ensuring the parallelism between the positioning supports, greatly avoiding the phenomenon of bearing ring axis tilting during movement due to differences in the spacing of the positioning supports, and also ensuring the uniformity of the contact force between the bearing ring and the positioning support, further improving the operational stability and smoothness of the device, as well as the pass rate of bearing ring appearance inspection.
[0015] In use, this utility model employs an elastic tensioning element to provide continuous preload to the bearing ring, ensuring that the positioning auxiliary frame always fits against the inner wall of the ring. This guarantees radial positioning accuracy while avoiding compression damage to the ring caused by rigid contact, further improving the effectiveness and efficiency of the device in practical applications.

Detailed Implementation
[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown:
[0026] This utility model provides a bearing outer diameter automatic measuring instrument feeding machine with a device to prevent scratching of bearing ring outer diameter. It includes a support frame 1, a limiting guide plate 2, a feeding auxiliary mechanism, a material support plate 4, and positioning pillars 5. The limiting guide plate 2 is slidably mounted on the upper end of the support frame 1. The feeding auxiliary mechanism is located on the outer side of the lower end of the limiting guide plate 2. The feeding auxiliary mechanism includes two drive screws 3, which are rotatably connected to the left and right ends of the support frame 1 respectively. The material support plate 4 is located above the limiting guide plate 2, and its left and right end faces are slidably connected to the support frame 1 using resistance-increasing frames 402. The two resistance-increasing frames 402 have a convex structure. Multiple positioning pillars 5 are evenly arranged and slidably mounted on the upper end of the material support plate 4.
[0027] Among them, two electric push rods 101 are fixedly connected to the upper side of the rear end of the support frame 1 by a T-shaped connecting frame; a connecting plate 102 is fixedly connected to the outer side of the piston rod at the front end of the electric push rod 101; multiple push plates 103 are evenly arranged and fixedly connected to the front end face of the connecting plate 102; the push plate 103 has a V-shaped frame structure.
[0028] The feeding auxiliary mechanism also includes a drive shaft 301 and a bevel gear transmission assembly 302. The drive shaft 301 is vertically rotatably mounted on the outside of the left-end drive screw 3, and the outer end of the drive shaft 301 is coaxially fixedly connected to the outside of the drive motor shaft. The bevel gear transmission assembly 302 is located between the left-end drive screw 3 and the drive shaft 301.
[0029] Among them, a transmission pulley 303 is coaxially fixedly connected to the bottom end face of the drive screw 3; a synchronous belt 304 is wound around the outside of the transmission pulley 303.
[0030] The outer sides of the left and right end faces of the limiting guide plate 2 are fixedly connected with transmission auxiliary blocks 305; the transmission auxiliary blocks 305 on the same side are threadedly connected to the drive screw 3.
[0031] The material support plate 4 has adjusting screws 401 threadedly connected to the left and right sides. The bottom end face of the adjusting screw 401 abuts against the limiting guide plate 2, so that the material support plate 4 and the limiting guide plate 2 maintain a suitable distance.
[0032] The specific usage and function of this embodiment are as follows:
[0033] In practical application, when the drive motor drives the shaft 301 to rotate, the bevel gear transmission assembly 302 pushes the left-end drive screw 3 to rotate. During the rotation of the left-end drive screw 3, the transmission pulley 303 and the synchronous belt 304 push the two drive screws 3 to rotate synchronously. During the simultaneous rotation of the two drive screws 3, the transmission auxiliary block 305 pushes the limiting guide plate 2 to slide up and down. During the upward sliding of the limiting guide plate 2, the material support plate 4 is pushed upward by the adjusting screw 401 to lift the bearing ring to a high position. At this time, the piston rod pushes the pusher plate 103 to slide. During the sliding of the pusher plate 103, it pushes the bearing ring to realize the automatic feeding of the bearing. When the limiting guide plate 2 slides downward, the material support plate 4 slides down and falls back to a low position due to gravity. The bearing ring naturally fills the material support plate 4, providing a material base for the next upward lifting.
[0034] Example 2: As shown in the attached document Figure 3 To be continued Figure 6 As shown:
[0035] Based on Embodiment 1, a spacing adjustment mechanism is also included, which is disposed on the bottom end face of the positioning support 5. The spacing adjustment mechanism includes: adjusting screws 602, and there are multiple adjusting screws 602, which are respectively vertically rotatably disposed on the outer side of the bottom end face of multiple positioning supports 5.
[0036] The spacing adjustment mechanism further includes: an adjustment support shaft 6 and an adjustment auxiliary block 601. The adjustment support shaft 6 is rotatably connected to the outer side of the lower end of the limiting guide plate 2. There are multiple adjustment auxiliary blocks 601, which are respectively fixedly connected to the outer side of the bottom end face of multiple positioning support columns 5. The adjustment auxiliary blocks 601 on the same side are threadedly connected to the adjustment screw 602. The outer end of the adjustment screw 602 is coaxially fixedly connected to a drive worm gear 603. A drive worm 604 is provided on the outer side of the drive worm gear 603, and the drive worm 604 meshes with the drive worm gear 603. Multiple drive worms 604 are coaxially fixedly connected to the adjustment support shaft 6.
[0037] Among them, multiple positioning auxiliary frames 501 are arranged circumferentially at the outer end of the positioning support column 5. The positioning auxiliary frame 501 is an arc-shaped frame structure. Multiple elastic tensioning members 502 are arranged vertically and fixedly connected between the positioning auxiliary frame 501 and the positioning support column 5.
[0038] The specific usage and function of this embodiment are as follows:
[0039] In use, after the bearing ring is fitted onto the outside of the positioning support 5, the positioning auxiliary frame 501 and the elastic tensioning member 502 are used to position the bearing ring, so that the inner wall of the bearing ring is in close contact with the positioning auxiliary frame 501. When the adjusting support shaft 6 is pushed to rotate, multiple driving worm gears 604 drive multiple driving worm wheels 603 and adjusting screws 602 to rotate synchronously. During the simultaneous rotation of multiple adjusting screws 602, multiple adjusting auxiliary blocks 601 push the adjusting support shaft 6 to slide simultaneously, thereby adjusting the distance between the positioning support 5 and the pusher plate 103.
