The ball loading assembly is used to feed a ball into the mold groove, and the upper mold can squeeze the ball in the mold groove when it moves toward the lower mold.

[0005] By adopting the above technical solution, corresponding upper and lower dies are set on the table, the lower die is provided with a die groove for placing the retaining frame, the upper die can move up and down along the table, the ball loading assembly can move in the vertical and horizontal directions of the table and deliver the ball to the die groove, the ball is placed in the corresponding hole in the retaining frame, and with the extrusion of the upper die, the ball can be pressed into the retaining frame, thereby completing the assembly, improving the quality of the assembly, and also improving the efficiency of the assembly.

[0006] Optionally, the ball loading assembly includes a ball loading plate and a ball blocking plate, the ball loading plate is arranged on the upper side of the ball blocking plate, a plurality of goal holes are provided on the ball loading plate, the goal holes are used to place a single ball, the ball blocking plate is provided with a delivery groove, the delivery groove and the goal hole are staggered, the ball blocking plate can move in a vertical direction, and after the ball blocking plate moves, the ball can roll from the goal hole to the delivery groove.

[0007] By adopting the above technical solution, a ball loading plate and a ball blocking plate are set. The ball loading plate is on the upper side and has a goal hole, and the ball blocking plate is on the lower side and has a delivery groove. When the ball blocking plate abuts the ball loading plate, the ball is blocked and cannot be delivered due to the misalignment of the delivery groove and the goal hole, while the ball blocking plate can move vertically. At this time, there is a gap between the ball loading plate and the ball blocking plate. The ball rolls down from the goal hole to the ball blocking plate and enters the delivery groove, thereby realizing the function of the ball loading assembly to controllably deliver the ball into the mold groove.

[0008] Optionally, a guide slope is further provided on the ball blocking plate at the delivery groove, and a side of the guide slope close to the delivery groove is lower than a side away from the delivery groove.

[0009] By adopting the above technical solution, a guide slope is set on the ball blocking plate, and the ball can move along the guide slope when falling out. Since the guide slope is set towards the delivery groove, the ball can roll more smoothly from the goal hole to the delivery groove.

[0010] Optionally, the ball loading assembly also includes a lower mold positioning plate, which can move along the vertical and horizontal directions of the table body. The lower mold positioning plate is arranged on the lower side of the ball blocking plate. A plurality of positioning grooves are opened in the lower mold positioning plate.

[0012] Optionally, a spring is provided between the lower die positioning plate and the ball blocking plate, one end of the spring is fixedly connected to the lower die positioning plate, and the other end of the spring is fixedly connected to the ball blocking plate, and the spring has a tendency to push the ball blocking plate toward the ball loading plate.

[0013] By adopting the above technical solution, a spring is arranged between the lower mold positioning plate and the ball blocking plate. Under the push of the spring, the ball blocking plate can abut the ball loading plate under normal circumstances, thereby limiting the passage of the ball. When the ball blocking plate is pushed, it will make space for the ball to pass through. At this time, the ball can enter the delivery groove of the ball blocking plate and be sent into the positioning groove of the lower mold positioning plate, thereby realizing the guidance of the ball loading.

[0014] Optionally, a ball counter is also provided on the platform, and the ball counter can move in the vertical and horizontal directions. The ball counter is set on the upper side of the ball loading tray, and the ball counter can abut the top of the ball loading tray. A ball loading channel is provided in the ball counter, and the ball loading channel passes through the ball counter. When the ball counter abuts the ball loading tray, the ball loading channel is blocked.

[0015] By adopting the above technical solution, the ball can be introduced into the ball counter. The ball can only be scored when it is aligned with the goal hole in the ball loading channel. Since each goal hole can only hold a single ball, after completing the delivery of a single ball, it is only necessary to move the ball counter to score a goal with balls at other positions, which further improves convenience.

[0016] Optionally, an induction switch is provided in the ball loading channel, and the induction switch is provided at the top of the ball loading channel. The induction switch is used to detect the number of balls in the ball loading channel. When the induction switch does not detect a ball, the ball counter stops.

DETAILED DESCRIPTION

[0028] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0029] A linear ball bearing assembly machine, such as Figure 1 and Figure 2 As shown, the table 1 includes a base 1, on which an upper die 2 and a lower die 21 are provided. The upper die 2 and the lower die 21 are arranged in a corresponding manner. The lower die 21 is provided with a die groove 211 for accommodating a retainer. The lower die 21 is fixedly connected to the table 1. The upper die 2 moves up and down along the table 1. The table 1 is also provided with a ball loading assembly 3. The ball loading assembly 3 can move along the vertical and horizontal directions of the table 1. The ball loading assembly 3 is used to feed a ball into the die groove 211. When the upper die 2 moves toward the lower die 21, it can squeeze the ball in the die groove 211. In a specific implementation, the shape of the retainer corresponds to the shape of the die groove 211 and can be exactly embedded in the die groove 211. The retainer has multiple grooves for the ball to be embedded. The material of the retainer can be rubber, plastic, etc. When the mold is closed, the ball is placed on the retainer by the ball loading assembly 3. After the mold is closed, the extrusion process can be completed and the ball is embedded in the retainer.

[0030] like Figure 1 and Figure 3 As shown, the ball loading assembly 3 includes a ball loading plate 31 and a ball blocking plate 32. The ball loading plate 31 is arranged on the upper side of the ball blocking plate 32. The ball loading plate 31 is provided with a plurality of goal holes 311, and the goal holes 311 are used to place a single ball. In specific implementation, the ball will first enter the goal hole 311 and wait for the ball to be loaded.

[0031] like Figure 1 and Figure 4As shown, the ball blocking plate 32 is provided with a delivery groove 321, which is offset from the goal hole 311. The ball blocking plate 32 can move in the vertical direction, and after the ball blocking plate 32 moves, the ball can roll from the goal hole 311 into the delivery groove 321. The ball blocking plate 32 is also provided with a guide slope 322 at the delivery groove 321, and the side of the guide slope 322 close to the delivery groove 321 is lower than the side away from the delivery groove 321. During specific implementation, the ball blocking plate 32 and the ball loading plate 31 are both driven in the vertical direction by independent cylinders. When driving, it is necessary to pay attention to not interfering with each other. Therefore, it is necessary to open a clearance hole, etc. At the same time, the entire ball loading assembly 3 is also provided with a cylinder group for horizontal and vertical driving. The ball loading plate 31 and the ball blocking plate 32 can move with the ball loading assembly 3 as a whole. When the ball blocking plate 32 is in contact with the ball loading plate 31, the ball blocking plate 32 can limit the delivery of the ball. When the ball blocking plate 32 moves away from the ball loading plate 31, it will make room for the ball. At this time, the ball will fall down into the ball blocking plate 32 and move along the guide slope 322 to the delivery groove 321.

[0032] like Figure 1 and Figure 5 As shown, the ball loading assembly 3 also includes a positioning plate for the lower die 21. The positioning plate can move along the vertical and horizontal directions of the table 1. The positioning plate is arranged on the lower side of the ball retaining plate 32. A plurality of positioning slots 331 are provided in the positioning plate of the lower die 21. The positioning slots 331 extend through the positioning plate of the lower die 21 and correspond to the position and shape of the ball holes 311. In specific implementation, the positioning slots 331 are used to align the position of the retaining frame within the die slot 211, serving as a guide during ball loading. The positioning plate of the lower die 21 is provided with an independent cylinder for vertical movement, while horizontal movement also occurs with the entire ball loading assembly 3.

[0033] like Figure 1 and Figure 5 As shown, a spring 332 is provided between the positioning disk of the lower mold 21 and the ball retaining plate 32. One end of the spring 332 is fixedly connected to the positioning disk of the lower mold 21, and the other end of the spring 332 is fixedly connected to the ball retaining plate 32. The spring 332 has a tendency to push the ball retaining plate 32 toward the ball loading plate 31. In specific implementation, under the push of the spring 332, the ball retaining plate 32 can abut the ball loading plate 31 in normal state, thereby restricting the passage of the ball. When the ball retaining plate 32 is pushed, it makes room for the ball to pass through. At this time, the ball can enter the delivery groove 321 of the ball retaining plate 32 and be delivered into the positioning groove 331 of the positioning disk of the lower mold 21, thereby achieving ball loading guidance.

[0034] like Figure 1As shown, the platform 1 is also provided with a ball counter 4, which can move in both vertical and horizontal directions. The ball counter 4 is located above the ball loading tray 31 and can abut the top of the ball loading tray 31. A ball loading channel 41 is provided within the ball counter 4. The ball loading channel 41 runs through the ball counter 4. When the ball counter 4 abuts the ball loading tray 31, the ball loading channel 41 is blocked. A sensor switch 411 is provided within the ball loading channel 41. The sensor switch 411 is located at the top of the ball loading channel 41 and is used to detect the number of balls in the ball loading channel 41. If the sensor switch 411 detects no balls, the ball counter 4 stops. A ball passing tube 42 is provided above the ball counter 4. The ball passing tube 42 is configured to correspond to the position and shape of the ball loading channel 41, and the interior of the ball passing tube 42 is connected to the interior of the ball loading channel 41. In specific implementation, the ball counter 4 is provided with a separate cylinder group for vertical and horizontal driving. When the ball counting channel is filled, the number of balls just corresponds to the number of balls required by the three retaining racks. Therefore, it is more accurate to use the ball counter 4 when replenishing the balls. When the ball counter 4 moves, the ball loading channel 41 is blocked when it is not connected to the goal hole 311, so the ball cannot fall out. The ball loading can only be achieved when the ball loading channel 41 is connected.

[0035] Working principle: This embodiment automatically replenishes and presses the balls, which can replenish and compact the balls in real time, thereby installing the balls into the corresponding retaining frames, which can effectively improve the processing quality and efficiency.

[0036] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
