[0002] In the prior art, a steel ball feeding mechanism is used to feed steel balls into the through holes of the distribution valve, and then a press-fitting mechanism is used to press the steel balls in the distribution valve. Since there are three surfaces on the distribution valve that need to be press-fitted with steel balls, it is also necessary to manually rotate the distribution valve and then perform steel ball feeding and press-fitting again. The entire press-fitting process is not only cumbersome in operation, but also greatly increases the labor and time costs, and reduces the press-fitting efficiency. Content of the Utility Model

[0028] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given with reference to the accompanying drawings.

[0029] As Figure 1 shown, the embodiment of the present application provides a ball pressing mechanism for a distribution valve, including a workbench 1, on which a frame body 2, a rotating mechanism 3, a pressing mechanism 4 and a limiting component 5 are arranged. The rotating mechanism 3 and the pressing mechanism 4 are installed on the frame body 2. The pressing mechanism 4 is located above the rotating mechanism 3. The driving end of the rotating mechanism 3 is provided with a fixture 6 for placing the distribution valve. The fixture 6 is provided with a positioning hole 61 for the steel ball to pass through. The rotating mechanism 3 is used to drive the fixture 6 to drive the distribution valve to rotate. The limiting component 5 is used to support the rotating mechanism 3. The pressing mechanism 4 is used to press the steel balls into the through holes on the three end faces of the distribution valve.

[0030] As Figure 2As shown, the press-fitting mechanism 4 includes a support frame 41, a horizontal driving mechanism 42, and a press-fitting device. The horizontal driving mechanism 42 is installed on the frame body 2. The driving end of the horizontal driving mechanism 42 is connected to the support frame 41. The support frame 41 is slidably matched with the frame body 2. The press-fitting device is installed on the support frame 41.

[0031] As Figure 2 As shown, the press-fitting device includes a lifting driving mechanism 43, a press-fitting assembly 44, and a steel ball conveying assembly 45. The lifting driving mechanism 43 is installed at the top of the support frame 41. The driving end of the lifting driving mechanism 43 is connected to the press-fitting assembly 44. The press-fitting assembly 44 is slidably matched with the support frame 41. The steel ball conveying assembly 45 is connected to the press-fitting assembly 44.

[0032] Specifically, the distribution valve steel ball press-fitting mechanism consists of a rotating mechanism 3, a press-fitting mechanism 4, and a limiting component 5. The distribution valve is placed in the fixture 6 of the rotating mechanism 3. The rotating mechanism 3 drives the fixture 6 to drive the distribution valve to rotate, so that the side of the distribution valve where the steel ball is to be installed is at the top. After rotating in place, the limiting component 5 supports the rotating mechanism 3 and the fixture 6. Then, the steel ball conveying assembly 45 driven by the horizontal driving mechanism 42 of the press-fitting mechanism 4 moves to the upper end of the fixture 6 and cooperates with the vibrating table in the prior art to convey the steel balls from the steel ball conveying assembly 45 through the fixture 6 into the through holes of the distribution valve. Then, the horizontal driving mechanism 42 drives the press-fitting assembly 44 to move above the fixture 6, and the lifting driving mechanism 43 drives the press-fitting assembly 44 to press the steel balls in the distribution valve. After the steel balls on one side of the distribution valve are pressed, the rotating mechanism 3 drives the fixture 6 to drive the distribution valve to rotate, so that the through hole on the second end face of the distribution valve is at the top, and the above operations are repeated to press the steel balls into the distribution valve in sequence. Among them, when the press-fitting assembly 44 presses the steel balls of the distribution valve, the limiting component 5 plays a role in supporting the distribution valve and providing a buffer force.

[0033] The above structure greatly improves the press-fitting efficiency of the distribution valve, and at the same time saves time and labor costs.

[0034] As Figure 3As shown, in one embodiment, the pressing assembly 44 of the ball pressing and installing mechanism of the distribution valve includes a pressing component 441 and a ball pressing component 442. The pressing component 441 includes an elastic component 001, a fixed block 002, and a pressing tube 003. The elastic component 001 includes a support plate 100, two connecting shafts 102, two springs 103, a connecting plate 101, and two sleeves 104. One end of the connecting shaft 102 is fixedly connected to the support plate 100, and the other end of the connecting shaft 102 is provided with a boss 105. The connecting plate 101 is sleeved on a section of the two connecting shafts 102 close to the boss 105, the sleeve 104 is sleeved on the connecting shaft 102, one end of the spring 103 abuts against the sleeve 104, and the other end of the spring 103 abuts against the connecting plate 101. The driving end of the lifting driving mechanism 43 is connected to the support plate 100, the connecting plate 101 is connected to the fixed block 002, one section of the pressing tube 003 is installed in the fixed block 002, and the other section of the pressing tube 003 is used to extend into the positioning hole 61 of the jig 6 to press the distribution valve. The ball pressing component 442 includes a fixed part 004 and a pressing head 005. The top of the fixed part 004 is connected to the support plate 100, the bottom of the fixed part 004 is connected to the pressing head 005, and the pressing head 005 extends into the pressing tube 003 to press the ball.

[0035] Specifically, the lifting driving mechanism 43 drives the pressing component 441 and the ball pressing component 442 to move towards the jig 6. The pressing tube 003 of the pressing component 441 first extends into the positioning hole 61 of the jig 6. Since the radius of the pressing tube 003 is greater than the radius of the through hole of the distribution valve, the pressing tube 003 presses the outside of the through hole of the distribution valve, so that the distribution valve cannot move. The lifting driving mechanism 43 continues to drive the pressing component 441 and the ball pressing component 442 to move downward. The pressing component 441 is compressed under the action of the spring 103 of the elastic component 001, and the pressing head 005 of the ball pressing component 442 passes through the pressing tube 003 to press the ball in the through hole.

[0036] In the above structure, after pressing the distribution valve, the ball is pressed. This setting greatly improves the accuracy of ball pressing.

[0037] As Figure 3 shown, in one embodiment, a pressure sensor 006 is provided between the support plate 100 and the fixed part 004 of the ball pressing and installing mechanism of the distribution valve.

[0038] Specifically, by setting the pressure sensor 006, the pressure value during the pressing of the pressing mechanism 4 can be monitored in real time.

[0039] As Figure 3As shown, in one embodiment, the steel ball transfer assembly 45 of the ball pressing mechanism for the distribution valve includes a fixing member 451 and a conduit 452. The conduit 452 is installed on the fixing member 451 and is used to transfer steel balls into the distribution valve.

[0040] Specifically, in the prior art, a vibrating table is connected to the conduit 452 to transfer steel balls according to the pressing frequency. The vibrating table transfers the steel balls into the conduit 452, and the lifting drive mechanism 43 drives the conduit 452 to extend into the positioning hole 61 so that the steel balls are transferred to the through hole of the distribution valve through the conduit 452. Among them, the radius of the conduit 452 is smaller than the radius of the positioning hole 61 of the fixture 6, and the radius of the conduit 452 is larger than the radius of the through hole of the distribution valve.

[0041] The above structure facilitates the accurate transfer of steel balls into the through hole of the distribution valve.

[0042] As Figure 3 shown, in one embodiment, a first photoelectric sensor 453 for detecting whether the steel balls are transferred into the distribution valve is provided on the fixing member 451 of the ball pressing mechanism for the distribution valve, and a detection hole for cooperating with the first photoelectric sensor 453 is provided on the conduit 452.

[0043] Specifically, the first photoelectric sensor 453 detects whether the steel balls pass through the conduit 452. If the steel balls do not pass through the conduit 452, the staff can be reminded in time for processing. This setting facilitates timely reminding the staff to detect the steel ball transfer situation.

[0044] As Figure 2 shown, in one embodiment, the horizontal drive mechanism 42 of the ball pressing mechanism for the distribution valve is a lead screw drive mechanism, and the lifting drive mechanism 43 is an electric cylinder.

[0045] Specifically, the lead screw drive mechanism drives the pressing assembly 44 and the steel ball transfer assembly 45 to move horizontally, and the electric cylinder drives the pressing assembly 44 to press the steel balls into the distribution valve, and the electric cylinder drives the steel ball transfer assembly 45 to transfer the steel balls. This setting greatly improves the moving efficiency of the pressing assembly 44 and the steel ball transfer assembly 45, and also improves the pressing efficiency of the pressing assembly 44.

[0046] As Figure 4 shown, in one embodiment, the rotating mechanism 3 of the ball pressing mechanism for the distribution valve includes a motor 31, a fixing plate 32 and a first cylinder 33. The motor 31 is fixedly connected to the fixing plate 32, the driving end of the motor 31 is connected to the fixture 6, the fixing plate 32 is sleeved on the driving end of the motor 31, the fixing plate 32 is slidably matched with the frame body 2, the first cylinder 33 is installed on the support frame 41, and the driving end of the first cylinder 33 is connected to the fixing plate 32. The first cylinder 33 is used to drive the fixing plate 32 to drive the motor 31 and the fixture 6 to move up and down.

[0047] Specifically, the motor 31 drives the jig 6 to drive the distribution valve to rotate, so that the side of the distribution valve to be installed with steel balls is located at the top. Then, the first cylinder 33 drives the fixing plate 32 to drive the jig 6 to move downward and abut against the limiting component 5, so that the limiting component 5 supports the distribution valve in the jig 6.

[0048] The above structure facilitates driving the distribution valve to rotate and also facilitates making the distribution valve abut against the limiting component 5.

[0049] As Figure 4 shown, in one embodiment, a second photoelectric sensor 34 for detecting whether the distribution valve in the jig 6 is placed in place is provided on the fixing plate 32 of the distribution valve steel ball pressing mechanism.

[0050] Specifically, the second photoelectric sensor 34 detects whether the distribution valve is placed on the jig 6. If not, the staff is timely reminded to handle it. This setting facilitates timely reminding the staff to check the placement situation of the distribution valve.

[0051] As Figure 5 shown, in one embodiment, the limiting component 5 of the distribution valve steel ball pressing mechanism includes a limiting frame 51 and a buffer 52. The position of the limiting frame 51 corresponds to the vertical position of the jig 6. The buffer 52 is installed in the limiting frame 51, and the buffer 52 is used to buffer the distribution valve.

[0052] Specifically, the limiting frame 51 plays a supporting role for the rotating mechanism 3. The buffer 52 is arranged in the limiting frame 51. When the pressing mechanism 4 presses the distribution valve, it can play a buffering role for the distribution valve.

[0053] As Figure 6 shown, in one embodiment, a fixing mechanism 7 is further provided on the workbench 1 of the distribution valve steel ball pressing mechanism. The fixing mechanism 7 includes a sliding block 71, a baffle 72, a second cylinder 73 and a third cylinder 74. The sliding block 71 is slidably connected to the workbench 1. The driving end of the second cylinder 73 is connected to the sliding block 71. The third cylinder 74 is installed on the sliding block 71. The driving end of the third cylinder 74 is connected to the baffle 72. The position of the baffle 72 corresponds to the horizontal position of the jig 6. The third cylinder 74 is used to drive the baffle 72 to fix the distribution valve in the jig 6.

[0054] Specifically, the second cylinder 73 drives the sliding block 71 to move to one side of the jig 6, and then the third cylinder 74 drives the push plate to fix the distribution valve on the jig 6. Therefore, when the pressing mechanism 4 presses the steel balls of the distribution valve in the jig 6, the situation that the distribution valve loosens from the jig 6 can be avoided.

[0055] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
