The cartridge 12 and the sleeve 11 are pressed together and fixed. A bullet head 13 is disposed in the guide cavity of the guide housing. The cartridge and sleeve are small in size and require high precision during assembly. Even slight misalignment may cause the pressing of the cartridge and sleeve to fail. Therefore, how to improve the pressing accuracy of the cartridge and sleeve has become a technical problem to be solved. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an assembly device for a solenoid valve guide housing, which can realize the assembly of the cartridge, sleeve and bullet head.

The carrier includes a fixed base for supporting the sleeve. A support plate that can move up and down relative to the fixed base is provided above the fixed base. The support plate has a positioning hole for the cartridge to be inserted. A pressing mechanism is located on one side of the rotating platform. The pressing mechanism includes a clamping component and a pressing component. The clamping component is used to push the bearing plate rotated below it to move downwards to approach the fixed seat. The pressing component includes a pressing head that can move up and down under the drive of a press. The pressing head can press the cartridge in the positioning hole into the sleeve on the fixed seat. The beneficial effects of this utility model are as follows: The carrier is used to initially position the sleeve and the cartridge. During the pressing process, the clamping assembly first presses the bearing plate downwards, causing the cartridge on the bearing plate to move down to a position close to the sleeve 11. Then, the pressure head presses the cartridge downwards, thus fixing the cartridge and the sleeve. The pressing mechanism uses two steps for pressing, ensuring precise alignment of the cartridge and the sleeve before pressing, thereby improving pressing accuracy.

[0005] Furthermore, the fixed base is provided with a support column that passes downward through the rotating platform, and the pressing mechanism also includes a supporting assembly that can support the support column upward; the supporting assembly includes a lifting component and a driving component, the lifting component is located below the support column and can be raised and lowered under the drive of the driving component. The supporting assembly supports the fixed base, transmitting the pressure of the press to the worktable and preventing the rotating platform from tilting.

[0006] Furthermore, the driving component includes a support cylinder and a push plate, the push plate being driven by the support cylinder to move linearly in a horizontal plane, and the push plate and the lifting component being provided with mutually cooperating inclined surfaces. Furthermore, the pressure head is also fixed with a guide pin, which can be inserted into the cartridge and abuts against the bullet head inside the sleeve after the cartridge and the sleeve are pressed into place.

[0007] Furthermore, the press is fixed on the upright frame, and the pressing assembly includes a lifting drive component fixed on the upright frame and a lifting plate connected to the lifting drive component. The lifting plate can abut against and press down on the support plate.

[0008] Furthermore, the support frame is also equipped with a limiting rod that limits the downward movement distance of the lifting plate, and the height of the limiting rod is adjustable.

[0009] Furthermore, the carrier also includes a fixed plate and a guide post that are fixedly connected. The fixed base is fixed on the fixed plate, the bearing plate moves up and down along the guide post, and a spring is sleeved on the guide post between the fixed plate and the bearing plate.

[0011] Furthermore, the assembly device also includes a bullet mounting mechanism, which is located in front of the pressing mechanism in the rotation direction of the rotating platform; The bullet mounting mechanism includes a conveyor line, a first cross-shaped moving assembly, and a first clamping assembly connected to the end of the first cross-shaped moving assembly. The conveyor line is used to convey bullets. The first clamping assembly can clamp the bullet at the outlet of the conveyor line and move it between the support plate and the fixed seat under the drive of the first cross-shaped moving assembly.

Detailed Implementation The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0014] The present invention provides an assembly device for a solenoid valve guide housing 1, which is used for press-fitting a sleeve 11 and a cartridge 12. Before press-fitting the sleeve 11 and the cartridge 12, a bullet head 13 needs to be placed inside the sleeve 11.

[0015] See appendix Figure 1 As shown, the assembly device includes a rotating platform 2, with multiple carriers 3 rotating synchronously with it distributed along its circumference. A bullet head mounting mechanism 4, a pressing mechanism 5, and a detection mechanism 6 are sequentially arranged on the outer side of the rotating platform 2 along its rotation direction. The bullet head 13 is placed into the sleeve 11 at the bullet head mounting mechanism 4. The pressing mechanism 5 is used to press the sleeve 11 and the cartridge 12 together. The detection mechanism 6 is used to detect the assembled guide housing 1. Four carriers 3 are provided; one carrier 3 is used for loading the sleeve 11 and the cartridge 12, and the other three carriers 3 are located in the working areas of the bullet head mounting mechanism 4, the pressing mechanism 5, and the detection mechanism 6, respectively.

[0016] See appendix Figure 5 As shown, the carrier 3 includes a fixed base 31 for supporting the sleeve 11. The sleeve 11 is manually placed on the fixed base 31, and when the sleeve 11 is placed on the fixed base 31, the upper end of the sleeve 11 extends out of the fixed base 31. A support plate 32 is provided above the fixed base 31, which can move up and down relative to the fixed base 31. The support plate 32 has a positioning hole 321 for the cartridge 12 to be inserted. The cartridge 12 is manually placed into the positioning hole 321, and the diameter of the cartridge 12 matches that of the positioning hole 321. When there is no external force, the cartridge 12 will not detach from the positioning hole 321. When pushed by an external force, the cartridge 12 will be pushed out of the positioning hole 321. The cartridge 12 and the sleeve 11 on the carrier 3 are coaxial.

[0017] See appendix Figure 2 and attached Figure 3 As shown, the pressing mechanism 5 is located on one side of the rotating platform 2. The pressing mechanism 5 includes a pressing assembly 51 and a pressing assembly 52. ​​The pressing assembly 51 is used to push the bearing plate 32, which has been rotated below it, downward to move closer to the fixed seat 31. The pressing assembly 52 includes a pressing head 522 that can move up and down under the drive of the press 521. The pressing head 522 can press the cartridge 12 in the positioning hole 321 into the sleeve 11 on the fixed seat 31. The pressing assembly 52 first presses the bearing plate 32 downward, so that the cartridge 12 on the bearing plate 32 moves down to a position close to the sleeve 11. After the position of the cartridge 12 is positioned, the pressing head 522 presses the cartridge 12 downward to fix the cartridge 12 and the sleeve 11.

[0018] In this embodiment, the carrier 3 is used to initially position the sleeve 11 and the cartridge 12. During the pressing process, the clamping assembly 51 first presses the bearing plate 32 downward, causing the cartridge 12 on the bearing plate 32 to move down to a position close to the sleeve 11. Then, the pressure head 522 presses the cartridge 12 downward, thus fixing the cartridge 12 and the sleeve 11. The pressing mechanism 5 uses two steps for pressing, ensuring that the cartridge 12 and the sleeve 11 are precisely aligned before pressing, thereby improving the pressing accuracy.

[0019] See appendix Figure 5 As shown, the carrier 3 also includes a fixed plate 33 and guide posts 34 that are fixedly connected. A fixed seat 31 is fixed on the fixed plate 33 and protrudes upward from the fixed plate 33. Four guide posts 34 are provided, arranged in a square pattern. The bearing plate 32 moves up and down along the guide posts 34. A spring 35 is sleeved on the guide post 34 between the fixed plate 33 and the bearing plate 32. The spring 35 limits the bearing plate 32 to a first height position. At this time, the fixed seat 31 on the fixed plate 33 and the bearing plate 32 are separated in the vertical direction, and the bullet head 13 can be installed into the sleeve 11 from between the fixed seat 31 and the bearing plate 32. When it is necessary to press the sleeve 11 and the cartridge 12, the pressing assembly 51 overcomes the elastic force of the spring 35 and pushes the bearing plate 32 downward.

[0020] A limiting plate 322 is provided on the support plate 32, surrounding the positioning hole 321. After the clamping assembly 51 pushes the support plate 32 downward, the cartridge 12 and the sleeve 11 will abut against each other. At this time, since the sleeve 11 is fixed, the support plate 32 may move downward relative to the sleeve 11. At this time, the upper end of the cartridge 12 will extend upward through the positioning hole 321. In this case, the setting of the limiting plate 322 can prevent the cartridge 12 from tilting and keep the cartridge 12 in a vertical position.

[0021] Because the carrier 3 is fixed on the rotating platform 2, and the part of the rotating platform 2 that holds the carrier 3 is suspended, the pressure head 522 applies a large downward force to the fixed seat 31 when it presses down, which may deform the rotating platform 2. Therefore, in one embodiment, the fixed seat 31 is provided with a support column 311 that passes downward through the rotating platform 2, and the pressing mechanism 5 also includes a support component 53 that can support the support column 311 upward. By providing the support component 53 to support the fixed seat 31, the pressure on the fixed seat 31 is transferred to the support component 53, which will not affect the levelness of the rotating platform 2.

[0022] See appendix Figure 4As shown, the supporting assembly 53 includes a lifting member 531 and a driving component. The lifting member 531 is located below the support column 311 and can be raised and lowered under the drive of the driving component. The driving component includes a support cylinder 532 and a push plate 533. The push plate 533 is driven by the support cylinder 532 to move linearly in a horizontal plane. The push plate 533 and the lifting member 531 are provided with mutually cooperating inclined surfaces. The support cylinder 532 is fixed on the worktable 7. The push plate 533 and the lifting member 531 both slide along the housing fixed on the worktable 7. The housing guides the movement of the push plate 533 and the lifting member 531, and at the same time transfers the force on the lifting member 531 to the worktable 7 fixed on the ground. In this embodiment, the inclined surfaces of the push plate 533 and the lifting member 531 cooperate to convert the horizontal thrust of the support cylinder 532 into the upward force of the lifting member 531. The inclined surfaces realize the conversion of the force direction and make reasonable use of space.

[0023] In one embodiment, see Appendix Figure 3 As shown, a guide pin 523 is also fixed on the press head 522. The guide pin 523 can be inserted into the cartridge 12 and abuts against the bullet head 13 inside the sleeve 11 after the cartridge 12 and the sleeve 11 are pressed into place. The guide pin 523 can be used as a position switch during pressing. When the guide pin 523 abuts against the bullet head 13, the guide pin 523 will be subjected to the pressure of the bullet head 13. At this time, the sensor in the press 521 senses this pressure, indicating that the cartridge 12 has been pressed into place. The press 521 can stop its operation and drive the press head 522 to move upward and reset.

[0024] The press 521 is fixed on the stand 54, and the stand 54 is fixed on the worktable 7. The pressing assembly 51 includes a lifting drive 511 fixed on the stand 54 and a lifting plate 512 connected to the lifting drive 511. The lifting plate 512 can abut against and press down the support plate 32.

[0025] To limit the downward movement distance of the lifting plate 512, a limiting rod 513 is also provided on the upright 54 to limit the downward movement distance of the lifting plate 512. When the lifting plate 512 and the limiting rod 513 come into contact, it can no longer move downward. At this time, the bearing plate 32 has been pressed down into place, and the spring cylinder 12 on the bearing plate 32 is now in contact with the sleeve 11.

[0026] In one embodiment, the height of the limiting rod 513 is adjustable to adjust the downward movement height of the lifting plate 512 according to usage requirements. For example, the limiting rod 513 is a screw threadedly connected to the upright frame 54; rotating the limiting rod 513 adjusts its height.

[0027] See appendix Figure 6As shown, the bullet mounting mechanism 4 includes a conveyor line 41, a first cross moving assembly 42, and a first clamping assembly 43 connected to the end of the first cross moving assembly 42. The conveyor line 41 is used to convey the bullet 13. The first clamping assembly 43 can clamp the bullet 13 at the outlet of the conveyor line 41 and move it between the support plate 32 and the fixed seat 31 under the drive of the first cross moving assembly 42. The first clamping assembly 43 places the clamped bullet 13 into the sleeve 11 on the fixed seat 31.

[0028] The conveyor line 41 is connected to the loading tray, which transports the bullet head 13 onto the conveyor line 41. The first cross-shaped moving component 42 consists of two combined linear modules that can drive the first clamping component 43 to move horizontally and vertically. After the first clamping component 43 clamps one bullet head 13 on the conveyor line 41, the first cross-shaped moving component 42 drives the first clamping component 43 to move horizontally to reach between the bearing plate 32 and the fixed seat 31. Then, the first cross-shaped moving component 42 drives the first clamping component 43 to move downward. When part of the bullet head 13 enters the sleeve 11, the first clamping component 43 releases the bullet head 13, and the bullet head 13 falls into the sleeve 11.

[0029] After the guide housing 1 is assembled, it is necessary to ensure that the height difference between the upper surface of the sleeve 11 and the upper surface of the bullet head 13 is within the set range. Therefore, a detection mechanism 6 is set up to detect the guide housing 1.

[0030] See appendix Figure 7 As shown, the detection mechanism 6 includes a second cross-shaped moving component 61, a second clamping component 62, and a detection component 63. The second clamping component 62 and the detection component 63 are both connected to the second cross-shaped moving component 61. The second clamping component 62 approaches the carrier 3 and clamps the sleeve 11 and the cartridge 12 pressed on the fixing seat 31 under the drive of the second cross-shaped moving component 61. The detection component 63 includes distance sensors for detecting the positions of the upper surface of the sleeve 11 and the upper surface of the bullet head 13, respectively.

[0031] The second cross-shaped moving assembly 61 consists of two combined linear modules that can drive the second clamping assembly 62 to move in both horizontal and vertical directions. Driven by the second cross-shaped moving assembly 61, the second clamping assembly 62 reaches the mounting base and clamps the guide housing 1, composed of the sleeve 11 and the cartridge 12, which are press-fitted onto the mounting base. Then, the second cross-shaped moving assembly 61 drives the first clamping assembly 43 to reset to one side of the rotating platform 2. At this time, two distance sensors detect the positions of the upper surfaces of the sleeve 11 and the cartridge 13, respectively, using the height difference between them for detection.

[0032] The detection mechanism 6 also includes a recycling bin 64. The second clamping component 62 can move to the top of the recycling bin 64. At this time, the detection component 63 performs the detection. When the detection result is unqualified, the second clamping component 62 releases the guide housing 1, allowing the guide housing 1 to fall into the recycling bin 64.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model.
