Description

Technical Field

[0001] This utility model relates to the field of ball cage technology, specifically to a ball cage forward and reverse detection feeding device. Background Technology

[0002] The CV joint, also known as a constant velocity joint, is a crucial component in a car's transmission system. Its function is to transmit engine power from the transmission to the drive wheels, propelling the car at high speeds. Many types of constant velocity joints are used in cars, with the CV joint and the tripod type being the most common. They are mainly composed of a sliding sleeve, a three-way shaft, a drive shaft, a star-shaped sleeve, a cage, and a bell-shaped housing. Because constant velocity joints transmit heavy driving torque, require high loads and high transmission precision, and are in high demand, and are also safety components, their main parts are all precision-forged. However, the inventors of this application discovered through on-site research that currently, in the CV joint production process, the feeding equipment on the production line cannot automatically identify the front and back of the CV joints. Workers must identify and inspect each one individually before feeding, which is time-consuming, labor-intensive, and increases the workload of workers. Utility Model Content

[0003] In view of the technical problem that the feeding equipment on the production line cannot automatically identify the front and back of the ball cage during the ball cage production process, and workers need to identify and inspect each one before feeding, which is time-consuming, labor-intensive and increases the labor intensity of workers, this utility model provides a ball cage front and back detection feeding device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A ball cage forward and reverse detection and feeding device includes a support frame, on which a conveyor belt and a control system are mounted. The device further includes a first blocking mechanism, a second blocking mechanism, a forward and reverse detection mechanism, a third blocking mechanism, a first pushing mechanism, a ball cage tilting mechanism, and a second pushing mechanism, all electrically connected to the control system. The first blocking mechanism, the second blocking mechanism, and the first pushing mechanism are sequentially and spaced apart and fixedly connected to a first side plate of the support frame. The forward and reverse detection mechanism, the ball cage tilting mechanism, and the second pushing mechanism are sequentially and spaced apart and fixedly connected to a second side plate of the support frame. The first pushing mechanism and the second pushing mechanism are arranged opposite to each other. The third blocking mechanism spans across the first and second side plates of the support frame and is located above the conveyor belt. The first blocking mechanism is adapted to perform the first detection of the ball cage moving forward on the conveyor belt. The first and second blocking mechanisms are adapted to block a ball cage moving forward on the conveyor belt a second time after the first blocking is canceled, and the conveyor belt spacing between the first and second blocking mechanisms is only suitable for one ball cage to pass through. The front and back detection mechanism is adapted to detect the front and back of the ball cage blocked for the second time. The third blocking mechanism is adapted to block a ball cage with the back side up after the front and back detection is detected for the third time. The first pushing mechanism is adapted to push the ball cage blocked for the third time onto the ball cage flipping mechanism. The ball cage flipping mechanism is adapted to flip the ball cage with the back side up to the front side up. The second pushing mechanism is adapted to push the ball cage with the front side up after flipping back onto the conveyor belt. The third blocking mechanism is also adapted to cancel the third blocking of the ball cage pushed back onto the conveyor belt.

[0006] Compared with the prior art, the ball cage forward and reverse detection feeding device provided by this utility model first places the ball cage to be processed on the running conveyor belt. The movement of the conveyor belt drives the ball cage forward. At the same time, the first blocking mechanism blocks the ball cage moving forward on the conveyor belt for the first time. Then, the first blocking mechanism cancels the blockage and the second blocking mechanism opens the blockage. At this time, a ball cage moves forward to the conveyor belt between the first and second blocking mechanisms and is blocked for the second time by the second blocking mechanism. Then, the forward and reverse detection mechanism detects the forward and reverse sides of the ball cage blocked for the second time. If the result of the forward and reverse detection is that the front is up, then the third blocking mechanism, the first pushing mechanism, the ball cage flipping mechanism, and the... The second pushing mechanism performs no operation, allowing the ball cage to continue moving forward on the conveyor belt after the second blocking mechanism cancels its block. If the front / back detection result indicates the back is facing up, the second blocking mechanism cancels its block while the third blocking mechanism activates its block. At this point, the ball cage with the back facing up will be blocked a third time by the third blocking mechanism. Then, the first pushing mechanism pushes the ball cage blocked for the third time onto the ball cage flipping mechanism, which flips the ball cage so that its front is facing up. Next, the second pushing mechanism pushes the flipped ball cage with its front facing up back onto the conveyor belt. Finally, the third blocking mechanism cancels its block, allowing the ball cage pushed back onto the conveyor belt to continue moving forward. This device can automatically identify the front and back of the ball cages on the conveyor belt, eliminating the need for workers to identify and inspect each cage individually before loading, saving time and labor, and reducing the labor intensity for workers.

[0007] Furthermore, the first blocking mechanism includes a first support plate and a first cylinder electrically connected to the control system via a wire. The first support plate is fixedly connected to the first side plate of the support frame, and the first cylinder is fixedly mounted on the surface of the first support plate.

The second support plate is fixedly connected to the first side plate of the support frame, and the second cylinder is fixedly mounted on the surface of the second support plate.

[0009] Furthermore, the forward and reverse detection mechanism includes a support base plate fixedly connected to the second side plate of the support frame. A support column is fixed on the support base plate. A telescopic cylinder electrically connected to the control system via a wire is fixed on the top of the support column. A connecting plate is fixed vertically downward on the piston rod of the telescopic cylinder. A vertical rod is fixed on the connecting plate. A contact element adapted to the front hole diameter of the ball cage is fixed at the lower end of the vertical rod. An infrared rangefinder electrically connected to the control system via a wire and facing the surface of the connecting plate is also fixed at the bottom of the telescopic cylinder housing.

[0010] Furthermore, the third blocking mechanism includes a support frame that spans the first and second side plates of the support frame. A third cylinder that is electrically connected to the control system via a wire is fixed to the front side of the crossbeam of the support frame. An L-shaped blocking block is fixedly connected to the piston rod of the third cylinder vertically downwards, with the long side of the L-shaped blocking block facing the conveyor belt.

[0011] Furthermore, both the first and second pushing mechanisms include a support plate fixedly connected to the side plate of the support frame. A pushing cylinder electrically connected to the control system via a wire is fixedly disposed on the surface of the support plate. A pushing block is fixedly connected to the end of the piston rod of the pushing cylinder. The surface of the pushing block near the conveyor belt is a concave arc-shaped surface.

[0012] Furthermore, the ball cage flipping mechanism includes a support base plate fixedly connected to the second side plate of the support frame. A drive motor electrically connected to the control system via a wire is fixedly installed on the surface of the support base plate. The motor shaft of the drive motor is horizontally fixed with a mounting plate. A clamping cylinder electrically connected to the control system via a wire is fixedly installed on the rear side of the mounting plate. The clamping cylinder is a double-acting cylinder. Connecting support bars are fixed on the telescopic rods at the upper and lower ends of the double-acting cylinder. A clamping block is fixedly connected to the end of the connecting support bar.

[0013] Furthermore, the device also includes a ball cage separating mechanism located in front of the third blocking mechanism. The ball cage separating mechanism includes a base fixedly connected to the first side plate and the second side plate of the support frame. A support crossbar located above the conveyor belt is supported on the surface of the base. Separating plates are fixedly connected to the two support crossbars located upstream and downstream of the conveyor belt. The distance between the bottom of the separating plate opposite the first blocking mechanism and the second blocking mechanism and the conveyor belt is smaller than the distance between the bottom of the separating plate opposite the first pushing mechanism and the conveyor belt.

[0014] Furthermore, the device also includes a discharge mechanism, which is a frame consisting of a first baffle, a lower bottom plate, a second baffle, and an upper top plate connected end to end.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please refer to Figure 1 and Figure 2 As shown, this utility model provides a ball cage forward and reverse detection feeding device, including a support frame 1, on which a conveyor belt 2 and a control system are arranged. The control system adopts an existing PCL control system well known to those skilled in the art. The device also includes a first blocking mechanism 3, a second blocking mechanism 4, a forward and reverse detection mechanism 5, a third blocking mechanism 6, a first pushing mechanism 7, a ball cage flipping mechanism 8, and a second pushing mechanism 9, which are electrically connected to the control system for control. The first blocking mechanism 3, the second blocking mechanism 4, and the first pushing mechanism 7 are sequentially and fixedly connected to the first side plate 11 of the support frame 1 at intervals. The forward and reverse detection mechanism 5, the ball cage flipping mechanism 8, and the second pushing mechanism 9 are sequentially and fixedly connected to the second side plate 12 of the support frame 1 at intervals. The first pushing mechanism 7 and the second pushing mechanism 9 are arranged opposite to each other to facilitate pushing the same ball cage. The third blocking mechanism 6 spans across the first side plate 11 and the second side plate 12 of the support frame 1 and is located above the conveyor belt 2. The first blocking mechanism 3 is adapted to perform the first blocking of the ball cage 100 moving forward on the conveyor belt 2. The second blocking mechanism 4 is adapted to block a ball cage moving forward on the conveyor belt 2 after the first blocking is canceled. The distance between the first blocking mechanism 3 and the second blocking mechanism 4 on the conveyor belt is only suitable for passing through one ball cage, so that the second blocking mechanism 4 can perform a front-back detection after blocking only one ball cage a second time. The front-back detection mechanism 5 is adapted to perform a front-back detection on the ball cage that is blocked for the second time to determine whether the front and back of the moving ball cage are reversed. The third blocking mechanism 6 is adapted to block a ball cage whose back side is on after the front-back detection. The third blocking mechanism 6 is adapted to push one of the cages blocked in the third blocking onto the cage flipping mechanism 8, which flips the cage with the reverse side up to the front side up, i.e., the cage flipping mechanism 8 flips the cage with the reverse side up 180 degrees. The second pushing mechanism 9 is adapted to push the cage with the front side up after flipping back onto the conveyor belt 2. The third blocking mechanism 6 is also adapted to cancel the third blocking of the cage pushed back onto the conveyor belt 2 so that the cage can continue to move forward on the conveyor belt.

[0023] Compared with the prior art, the ball cage forward and reverse detection feeding device provided by this utility model first places the ball cage to be processed on the running conveyor belt. The movement of the conveyor belt drives the ball cage forward. At the same time, the first blocking mechanism blocks the ball cage moving forward on the conveyor belt for the first time. Then, the first blocking mechanism cancels the blockage and the second blocking mechanism opens the blockage. At this time, a ball cage moves forward to the conveyor belt between the first and second blocking mechanisms and is blocked for the second time by the second blocking mechanism. Then, the forward and reverse detection mechanism detects the forward and reverse sides of the ball cage blocked for the second time. If the result of the forward and reverse detection is that the front is up, then the third blocking mechanism, the first pushing mechanism, the ball cage flipping mechanism, and the... The second pushing mechanism performs no operation, allowing the ball cage to continue moving forward on the conveyor belt after the second blocking mechanism cancels its block. If the front / back detection result indicates the back is facing up, the second blocking mechanism cancels its block while the third blocking mechanism activates its block. At this point, the ball cage with the back facing up will be blocked a third time by the third blocking mechanism. Then, the first pushing mechanism pushes the ball cage blocked for the third time onto the ball cage flipping mechanism, which flips the ball cage so that its front is facing up. Next, the second pushing mechanism pushes the flipped ball cage with its front facing up back onto the conveyor belt. Finally, the third blocking mechanism cancels its block, allowing the ball cage pushed back onto the conveyor belt to continue moving forward. This device can automatically identify the front and back of the ball cages on the conveyor belt, eliminating the need for workers to identify and inspect each cage individually before loading, saving time and labor, and reducing the labor intensity for workers.

[0024] For a specific embodiment, please refer to Figure 1 As shown, the first blocking mechanism 3 includes a first support plate 31 and a first cylinder 32 electrically connected to the control system via a wire. The first support plate 31 is fixedly connected to the first side plate 11 of the support frame 1. The first cylinder 32 is fixedly disposed on the surface of the first support plate 31. The piston rod of the first cylinder 32 can extend onto the conveyor belt 2 to block the forward ball cage for the first time.

[0025] For a specific embodiment, please refer to Figure 1 As shown, the second blocking mechanism 4 includes a second support plate 41 and a second cylinder 42 electrically connected to the control system via a wire. The second support plate 41 is fixedly connected to the first side plate 11 of the support frame 1. The second cylinder 42 is fixedly disposed on the surface of the second support plate 41. The piston rod of the second cylinder 42 can extend onto the conveyor belt 2 to block the forward ball cage for the second time.

[0026] For a specific embodiment, please refer to Figure 1As shown, the forward and reverse detection mechanism 5 includes a support base plate 51 fixedly connected to the second side plate 12 of the support frame 1. A support column 52 is fixed on the support base plate 51. A telescopic cylinder 53, which is electrically connected to the control system via a wire, is fixed to the top of the support column 52. A connecting plate 54 is fixed vertically downward on the piston rod of the telescopic cylinder 53. A vertical rod 55 is fixed on the connecting plate 54. A contact member 56, which is adapted to the front hole diameter of the ball cage, is fixed to the lower end of the vertical rod 55. An infrared rangefinder 57, which is electrically connected to the control system via a wire and is opposite to the surface of the connecting plate 54, is also fixed to the bottom of the housing of the telescopic cylinder 53. The infrared rangefinder 57 can detect the distance from the connecting plate 54. The specific structure and working principle of the infrared rangefinder 57 are well known to those skilled in the art, and therefore will not be described in detail here. Specifically, the ball cage in this application has a front and back side, and the apertures of the front and back sides are also different. The front side (drive side) is usually connected to the drive shaft spline, and the aperture is smaller to ensure a tight fit. The aperture of the back side is larger, usually 1mm larger than the aperture of the front side, in order to accommodate the sliding rail or grease cavity of the three-pivot bearing, ensuring the free movement of the bearing in the housing. The inventor of this application uses this characteristic of the ball cage to detect its front and back sides. When the forward and reverse detection mechanism 5 in this embodiment is working, the piston rod of the telescopic cylinder 53 first drives the connecting plate 54 to move downward, thereby driving the contact member 56 to move downward through the vertical rod 55 on the connecting plate 54. When the contact member 56 moves downward and touches the hole wall on the front or back of the ball cage, it will stop. Since the hole diameter on the front of the ball cage is smaller than the hole diameter on the back, the downward movement distance of the contact member 56 to touch the hole wall on the front of the ball cage is shorter than the downward movement distance of the contact member 56 to touch the hole wall on the back of the ball cage. The downward movement distance on the connecting plate 54 is also the same. At this time, the distance between the infrared rangefinder 57 and the connecting plate 54 will also have the same characteristics. The infrared rangefinder 57 will feed back such distance characteristics to the control system to decide whether to control the third blocking mechanism 6, the first pushing mechanism 7, the ball cage flipping mechanism 8 and the second pushing mechanism 9 to perform their respective related operations. Specifically, if the distance between the distance connecting plates 54 detected by the infrared rangefinder 57 is within the preset value (the distance corresponding to the front of the ball cage), the third blocking mechanism 6, the first pushing mechanism 7, the ball cage flipping mechanism 8, and the second pushing mechanism 9 will not perform their respective related operations. Conversely, if the distance between the distance connecting plates 54 detected by the infrared rangefinder 57 is not within the preset value range, that is, the distance is the distance corresponding to the back of the ball cage, the control system will control the third blocking mechanism 6, the first pushing mechanism 7, the ball cage flipping mechanism 8, and the second pushing mechanism 9 to perform their respective related operations.

[0027] For a specific embodiment, please refer to Figure 1As shown, the third blocking mechanism 6 includes a support frame 61 that spans the first side plate 11 and the second side plate 12 of the support frame 1. A third cylinder 62, which is electrically connected to the control system via a wire, is fixed to the front side of the crossbeam of the support frame 61. An L-shaped blocking block 63 is fixedly connected to the piston rod of the third cylinder 62 vertically downward. The long side of the L-shaped blocking block 63 faces the conveyor belt 2. Thus, under the action of the piston rod of the third cylinder 62, the L-shaped blocking block 63 can move down to a position close to the conveyor belt 2 to block a ball cage moving forward on it for the third time.

[0028] For a specific embodiment, please refer to Figure 1 As shown, the first pushing mechanism 7 and the second pushing mechanism 9 have the same structure, both including a support plate 71 fixedly connected to the side plate of the support frame 1. A pushing cylinder 72 electrically connected to the control system via a wire is fixedly installed on the surface of the support plate 71. A pushing block 73 is fixedly connected to the end of the piston rod of the pushing cylinder 72. The surface of the pushing block 73 near the conveyor belt 2 is a concave arc-shaped surface. Thus, the pushing block 73 can be moved horizontally under the action of the piston rod of the pushing cylinder 72 to push the ball cage that was blocked for the third time onto the ball cage flipping mechanism 8 for flipping.

[0029] For a specific embodiment, please refer to Figure 1 As shown, the ball cage flipping mechanism 8 includes a support base plate (not shown) fixedly connected to the second side plate 12 of the support frame 1. A drive motor 81, which is electrically connected to the control system via a wire, is fixedly mounted on the surface of the support base plate. A mounting plate 82 is horizontally fixed to the motor shaft of the drive motor 81. A clamping cylinder 83, which is electrically connected to the control system via a wire, is fixedly mounted on the rear side of the mounting plate 82. The clamping cylinder 83 is a double-acting cylinder. Connecting supports 84 are fixed to the telescopic rods at the upper and lower ends of the double-acting cylinder. Clamping blocks 85 are fixedly connected to the ends of the connecting supports 84. Thus, the two clamping blocks 85 retract inward at the piston rods at the upper and lower ends of the double-acting cylinder, thereby driving the piston rods to retract inward. The first pushing mechanism 7 can push over and clamp a ball cage placed on the surface of the lower clamping block (which is initially flush with the surface of the conveyor belt 2). Then, the clamping cylinder 83 rotates 180 degrees under the action of the motor shaft of the drive motor 81, thereby flipping the ball cage so that the front is facing up. Then, the drive motor 81 stops, and the piston rods at the upper and lower ends of the clamping cylinder 83 extend outward, causing the flipped lower clamping block surface (actually the upper clamping block surface before flipping) to move down to be flush with the surface of the conveyor belt 2 (equivalent to the lower clamping block surface being flush with the conveyor belt surface in the initial state). At this time, the ball cage on the lower clamping block surface can be pushed back onto the conveyor belt 2 by the second pushing mechanism 9.

[0030] For a specific embodiment, please refer to Figure 1As shown, the device also includes a ball cage separating mechanism 10 located in front of the third blocking mechanism 6. The ball cage separating mechanism 10 includes a base 101 fixedly connected to the first side plate 11 and the second side plate 12 of the support frame 1. The surface of the base 101 supports a support crossbar 102 located above the conveyor belt 2. Two supporting crossbars 102 located upstream and downstream of the conveyor belt 2 are fixedly connected to a separating plate 103, thereby separating the conveyor belt 2 to facilitate the passage of a ball cage. The distance between the bottom of the separating plate opposite the first blocking mechanism 3 and the second blocking mechanism 4 and the conveyor belt 2 is smaller than the distance between the bottom of the separating plate 103 opposite the first pushing mechanism 7 and the conveyor belt 2. This facilitates the piston rods of the first blocking mechanism 3 and the second blocking mechanism 4 to extend onto the conveyor belt 2 for blocking, and facilitates the piston rod of the first pushing mechanism 7 to extend and drive the pushing block 73 to push on the conveyor belt 2.

[0031] For a specific embodiment, please refer to Figure 1 As shown, the device also includes a discharge mechanism 11, which is a frame consisting of a first baffle 111, a lower bottom plate 112, a second baffle 113, and an upper top plate 114 connected end to end. The first baffle 111 is fixed to the inner side of the first side plate 11 of the support frame 1, and the second baffle 113 is fixed to the inner side of the second side plate 12 of the support frame 1. The lower bottom plate 112 is disposed adjacent to the surface of the conveyor belt 2 and the front side of the lower bottom plate 112 is inclined, which facilitates a ball cage to move forward to the surface of the lower bottom plate 112 and pause to discharge and wait. When the next ball cage moves forward to the surface of the lower bottom plate 112, it will abut against the ball cage waiting to discharge, causing the ball cage to fall from the surface of the lower bottom plate 112 onto the subsequent conveyor belt to continue moving forward.

[0032] For a specific embodiment, please refer to Figure 1 As shown, the device also includes a ball cage guiding mechanism, which includes two guide bars 121 arranged in a V-shape. One end of the two guide bars 121 is fixedly connected to the bottom of the support crossbar 102 on the second side of the partition plate 103, or welded. The other end of the two guide bars 121 is fixedly connected to the surface of the lower base plate 112, or welded. Thus, the ball cage that has been cleared of the third obstruction can be guided to the surface of the lower base plate 112 through the two guide bars 121 arranged in a V-shape to pause and wait for discharge.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
