Description

Technical Field

[0001] This utility model relates to the field of bearing surface processing technology, specifically a special positioning fixture for bearing surface processing equipment. Background Technology

[0002] In the bearing manufacturing industry, the machining accuracy of the inner circle surface of the bearing ring directly determines the assembly performance and service life of the bearing. As a core auxiliary component in the machining process, the stability, versatility and automation of positioning fixtures play a key role in production efficiency and product quality.

[0003] Currently, the positioning structure of common bearing surface machining positioning fixtures on the market is simple, and most of them adopt a fixed clamping method, which can only be adapted to specific models of bearing rings. When it is necessary to process bearing rings of different sizes and specifications, the tooling fixtures need to be changed frequently, which not only increases the production preparation time, but also increases the equipment investment cost, and has poor flexibility and versatility. In addition, the existing bearing machining positioning fixtures are not stable enough. Some fixtures are fixed by simply pressing down from the top and bottom or limiting from the side. During the machining process, the bearing ring is easily displaced due to cutting force, friction and other forces, which affects the machining accuracy of the inner circle surface and thus produces unqualified products. Third, the degree of automation is low. When loading, the bearing rings need to be placed one by one manually, and when unloading, manual intervention is also required to remove the processed workpieces. This not only increases the labor intensity of the operators, but also makes it difficult to adapt to modern assembly line production systems, thus restricting the improvement of overall production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a special positioning fixture for bearing surface processing equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special positioning fixture for bearing surface processing equipment, comprising a fixed frame, a support seat hinged to the fixed frame, a first electric push rod hinged to the fixed frame, the output end of the first electric push rod being hinged to the bottom end of the support seat, a mounting frame at the top of the fixed frame, a second electric push rod on the mounting frame, a clamping seat at the bottom end of the second electric push rod, clamping protrusions at both ends of the top of the support seat and both ends of the bottom of the clamping seat, an inlet frame at the input end of the support seat and an outlet frame at the output end, a first limiting frame on one side of the support seat located on the outlet frame, a movable adjustment component on the fixed frame in cooperation with the first limiting frame, and a feeding limiting structure at the inlet frame.

[0006] The present invention is further configured such that the movable adjustment component includes a displacement adjustment structure and a telescopic adjustment structure.

[0007] The present invention is further configured such that the displacement adjustment structure includes a fixed seat, the fixed seat is installed on the back of the fixed frame, a third electric push rod is horizontally mounted on the fixed seat, and the telescopic adjustment structure is installed on the output end of the third electric push rod. When the third electric push rod is activated, the movement of the mounting block can be controlled by the third electric push rod, thereby realizing the movement of the first limiting frame. In this way, the limiting position of the first limiting frame can be flexibly adjusted within a certain range to adapt to the limiting of different types of bearing rings.

[0008] The present invention is further configured such that the telescopic adjustment structure includes a mounting block, the mounting block is mounted on the output end of the third electric push rod, a fourth electric push rod is mounted on the mounting block along the horizontal longitudinal direction, the first limiting frame is mounted on the output end of the fourth electric push rod, and a telescopic groove is provided on the fixed frame. The first limiting frame slides within the telescopic groove. When the fourth electric push rod is activated, the telescopic control of the first limiting frame can be realized through the telescopic control of the fourth electric push rod, thereby realizing the movement and telescopic extension of the first limiting frame in the telescopic groove position. When the bearing ring moves to the support seat, the first limiting frame is positioned on the output side of the support seat, realizing the loading limit and improving the positioning accuracy and stability. After the inner circle surface of the bearing ring is processed, the fourth electric push rod is controlled to retract, so that the first limiting frame retracts to the back side of the fixed frame through the telescopic groove, releasing the limit and realizing smooth unloading.

[0009] The present invention is further configured such that second limiting telescopic rods are provided on both sides of the second electric push rod. The provision of the second limiting telescopic rods can improve the load performance of the second electric push rod and improve the clamping stability of the clamping seat.

[0010] The present invention is further configured such that fourth limiting telescopic rods are provided on both sides of the fourth electric push rod. The provision of the fourth limiting telescopic rods can improve the load-bearing performance of the fourth electric push rod and avoid the impact of the bearing ring on the fourth electric push rod when the first limiting frame is in position during movement.

[0011] The present invention is further configured such that a support seat is provided on the fixed frame, the support seat is located at the bottom of the other end of the support seat away from the hinge end, and the support seat is in a horizontal state when it is erected on the support seat. The support seat can improve the stability of the support seat when bearing load, and further improve the stability of the bearing ring when the inner circle surface is machined.

[0012] The present invention is further configured such that the inlet frame and the outlet frame are inclined and both include a guide plate. Guide side plates are provided on both sides of the guide plate. The guide plate provides bottom support during the transfer of the bearing ring. The guide side plates can limit the bearing ring during the transfer process. The inclined configuration allows the bearing to roll automatically under its own weight. The present invention is further configured such that the feeding limiting structure includes a second limiting frame, a fifth electric push rod is provided on the fixed frame, the output end of the fifth electric push rod is connected to the second limiting frame, a limiting groove is provided on the fixed frame, the second limiting frame slides in the limiting groove and is located at the tail end of the guide frame, the fifth electric push rod is activated, the extension and retraction of the second limiting frame in the limiting groove can be controlled by the fifth electric push rod, thereby realizing the limiting of the bearing ring on the guide frame when feeding, and realizing the single feeding of the bearing ring on the guide frame to the support seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Improve the positioning stability of bearing rings during machining: This tooling forms a four-point positioning and clamping structure through two sets of clamping protrusions on the top of the support seat and the bottom of the clamping seat, which can firmly fix the bearing rings; at the same time, the second limit telescopic rods on both sides of the second electric push rod can enhance the load performance of the push rod, and the support seat can also improve the load-bearing stability of the support seat, further avoiding machining displacement, ensuring machining accuracy, and providing a reliable positioning foundation for high-quality machining.

[0014] 2. Achieve automated unloading and efficient loading: After processing, first control the second electric push rod to drive the clamping seat to rise and release the clamping, then control the fourth electric push rod to retract and release the limit, and finally start the first electric push rod to make the support seat flip, allowing the bearing ring to automatically slide into the inclined guide frame to complete the unloading; during loading, the inclined guide frame uses the bearing ring's own weight to achieve automatic movement, and in conjunction with the second limit frame controlled by the fifth electric push rod, it can achieve precise loading of a single bearing ring, reduce manual operation, and greatly improve the automation level and overall efficiency of the processing flow.

[0015] 3. Adaptable to different bearing ring models: The tooling is equipped with a displacement adjustment structure consisting of a third electric push rod, which can control the lateral movement of the first limit frame. Combined with the longitudinal extension and retraction adjustment of the fourth electric push rod, the limiting position of the first limit frame can be flexibly adjusted. Furthermore, the clamping protrusions on the support and clamping seats can accommodate the clamping and fixing of different bearing ring models within the movement range. Thus, the combination of these two structures allows the tooling to adapt to different bearing ring models within a certain size range, eliminating the need for frequent tooling changes, enhancing equipment versatility, reducing production changeover costs, and improving processing flexibility and convenience.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution: Please refer to Figures 1-5 A special positioning fixture for bearing surface processing equipment includes a fixed frame 1, a support seat 2 hinged to the fixed frame 1, a first electric push rod 3 hinged to the fixed frame 1, the output end of the first electric push rod 3 hinged to the bottom end of the support seat 2, a mounting frame 4 at the top of the fixed frame 1, a second electric push rod 5 on the mounting frame 4, a clamping seat 6 at the bottom end of the second electric push rod 5, clamping protrusions 7 at both ends of the top of the support seat 2 and both ends of the bottom of the clamping seat 6, an inlet frame 8 at the input end of the support seat 2 and an outlet frame 9 at the output end, a first limiting frame 10 on one side of the support seat 2 located on the outlet frame 9, a movable adjustment component on the fixed frame 1 in cooperation with the first limiting frame 10, and a feeding limiting structure at the inlet frame 8.

[0020] Please see Figures 1-5 As one implementation of the movable adjustment assembly: the movable adjustment assembly includes a displacement adjustment structure and a telescopic adjustment structure.

[0021] Please see Figures 1-5As one embodiment of the displacement adjustment structure: the displacement adjustment structure includes a fixed base 11, which is installed on the back of the fixed frame 1. A third electric push rod 12 is horizontally mounted on the fixed base 11, and the telescopic adjustment structure is installed at the output end of the third electric push rod 12. The third electric push rod 12 is activated, which controls the movement of the mounting block 13, thereby moving the first limit frame 10. In this way, the limiting position of the first limit frame 10 can be flexibly adjusted within a certain range to adapt to the limiting of different types of bearing rings.

[0022] Please see Figures 1-5 As one embodiment of the telescopic adjustment structure: the telescopic adjustment structure includes a mounting block 13, which is mounted on the output end of the third electric push rod 12. A fourth electric push rod 14 is mounted on the mounting block 13 along the horizontal longitudinal direction. A first limiting frame 10 is mounted on the output end of the fourth electric push rod 14. A telescopic groove 15 is provided on the fixed frame 1, and the first limiting frame 10 slides within the telescopic groove 15. Activate the fourth electric push rod 14. Through the extension and retraction control of the fourth electric push rod 14, the extension and retraction control of the first limit frame 10 can be realized, thereby realizing the movement and extension of the first limit frame 10 in the position of the extension groove 15. When the bearing ring moves onto the support seat 2, the first limiting frame 10 is positioned on the output side of the support seat 2, thereby achieving feeding limit and improving positioning accuracy and stability. After the inner surface of the bearing ring is machined, the fourth electric push rod 14 is retracted, causing the first limit frame 10 to retract to the back side of the fixed frame 1 through the telescopic groove 15, releasing the limit and achieving smooth unloading.

[0023] Please see Figures 1-5 As one implementation of the second electric push rod 5: the second electric push rod 5 is provided with second limiting telescopic rods 16 on both sides. The provision of the second limiting telescopic rods 16 can improve the load performance of the second electric push rod 5 and improve the clamping stability of the clamping seat 6.

[0024] Please see Figures 1-5 As one embodiment of the fourth electric push rod 14: the fourth electric push rod 14 is provided with a fourth limiting telescopic rod 17 on both sides. The setting of the fourth limiting telescopic rod 17 can improve the load-bearing performance of the fourth electric push rod 14 and avoid the impact of the bearing ring on the fourth electric push rod 14 when the first limiting frame 10 is in position during movement.

[0025] Please see Figures 1-5As one embodiment of the support base 2: a support base 18 is provided on the fixed frame 1. The support base 18 is located at the bottom of the other end of the support base 2 away from the hinge end. When the support base 2 is erected on the support base 18, it is in a horizontal state. The support seat 18 can improve the stability of the support seat 2 under load, and further improve the stability of the bearing ring when the inner circle surface is machined.

[0026] In this utility model, the inlet frame 8 and the outlet frame 9 are inclined and both include a guide plate 19, and guide side plates 20 are provided on both sides of the guide plate 19. The bottom support of the bearing ring is achieved by the guide plate 19 during the transfer process. The guide side plate 20 can limit the bearing ring during the transfer process. The tilt setting allows the bearing to roll automatically under its own weight. Please see Figures 1-5 As one implementation of the feeding limiting structure: the feeding limiting structure includes a second limiting frame 21, a fifth electric push rod 22 is provided on the fixed frame 1, the output end of the fifth electric push rod 22 is connected to the second limiting frame 21, a limiting groove 23 is provided on the fixed frame 1, the second limiting frame 21 slides in the limiting groove and is located at the tail end of the guide frame 8; The fifth electric push rod 22 is activated, which controls the extension and retraction of the second limit frame 21 within the limit groove 23, thereby achieving the limit when the bearing ring on the guide frame 8 is loaded, and thus achieving the single loading of the bearing ring on the guide frame 8 when it moves to the support seat 2.

[0027] In summary, the working principle and specific workflow of this utility model are as follows: In use, the bearing ring to be machined is fed through the guide frame 8. Since the guide frame 8 is tilted, the bearing ring will automatically move along the guide frame 8 to the support seat 2 under its own gravity, and the movement position is restricted by the first limiting frame 10. At the same time, the two sets of clamping protrusions 7 on the support seat 2 can achieve the final positioning support. Then, the second electric push rod 5 is activated, and the pressure seat 6 is lowered by the second electric push rod 5, so that the two sets of clamping protrusions 7 at the bottom of the pressure seat 6 are pressed against the top of the bearing ring; In this way, the four-point positioning and clamping of the bearing ring during the inner ring surface machining can be achieved by the cooperation of the upper and lower sets of clamping convex 7, thereby improving the positioning and clamping stability of the bearing ring during the inner circle surface machining. Therefore, the clamped bearing ring can be used with existing bearing ring inner circle machining equipment for bearing ring inner circle machining. The specific machining process is all existing technology, and the machining equipment used can be realized by existing products. This utility model will not elaborate on this part.

[0028] After processing is completed, the second electric push rod 5 is controlled to drive the clamping seat 6 to rise, releasing the clamping of the bearing ring. Simultaneously, the fourth electric push rod 14 is controlled to retract, causing the first limiting frame 10 to move along the telescopic groove 15 towards the fixed frame 1, releasing the limitation on the bearing ring. Then, the first electric push rod 3 is activated. The first electric push rod 3 can control the support seat 2 to flip, so that the bearing ring on the support seat 2 can be flipped and smoothly enter the guide frame 9 to achieve automatic unloading. Then, the first electric push rod 3 is retracted, causing the support 2 to rotate and be re-erected on the support 18 for the next round of processing. Then, the fifth electric push rod 22 is retracted, allowing the second limit frame 21 to move, so that the bearing ring on the guide frame 8 can re-enter the support seat 2 to achieve a new round of processing; This utility model is equipped with a third electric push rod 12 in conjunction with the first limiting frame 10. In this way, when processing bearing rings of different models, the third electric push rod 12 can be activated. The third electric push rod 12 can control the movement of the mounting block 13. The mounting block 13 can control the fourth electric push rod 14 to drive the movement of the first limiting frame 10, thereby realizing the flexible adjustment of the limiting position of the first limiting frame 10. The present invention preferably provides a corrugated telescopic cover for protection at the telescopic groove 15 position and a dustproof cover for protection at the limiting slide groove 23 position; In this utility model, the operation of electrical components such as electric push rods can be controlled by a PLC control system according to a set program.
