Technical Field
[0001] The invention relates to the technical field of pin press-fitting, and in particular to integrated pin press-fitting and detection equipment for electric compressors. Background Art
[0002] Pin press-fitting is a mechanical installation method that secures the pin to the product by creating an interference fit between the pin and the pin hole, and then pressing the pin into the pin hole. It is usually used to fix and position parts or in scenarios where repeated use is required. It is commonly used in the automotive manufacturing industry, 3C electronic equipment, automation industry and other fields. Through pin press-fitting, production capacity can be greatly improved and product quality and qualification rate can be controlled.
[0003] In actual production, it is very common that a product needs to be pressed into two pins of different sizes. However, pins of different sizes often need to be adapted to different special equipment in the loading and pressing links. This means that in the current production process, a product must pass through two independent pressing stations in sequence to complete the pressing of all pins. At each pressing station, a series of tedious and critical operating steps are required, including precise positioning of the product, completion of the pin picking action, ensuring that the pin and the pin hole are accurately aligned, and finally the press performs a downward pressing operation to complete the pressing. This results in a significant increase in the overall time consumption when pressing products that need to implant two different sizes of pins, and production efficiency is significantly restricted. Based on this, the present invention purposely provides an electric compressor pin pressing and detection integrated equipment that can quickly and accurately realize the pressing of two different sizes of pins at one station.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0018] See also Figure 1-Figure 7 As shown, the present invention is an integrated device for press-fitting and detecting pins of an electric compressor, comprising: Y-axis servo module 1, a clamping tool 2 is slidably installed on the Y-axis servo module 1, and the clamping tool 2 is driven to move by the built-in driving source of the Y-axis servo module 1, a loading tool 4 is provided at one end of the Y-axis servo module 1, and a detection tool 5 is provided at the other end of the Y-axis servo module 1, a base plate 6 is provided between the loading tool 4 and the detection tool 5, four support rods 9 are fixedly installed on the base plate 6, and the top ends of the four support rods 9 are abutted with a press-fitting block 10, the Y-axis servo module 1 is located between the base plate 6 and the press-fitting block 10, the loading tool 4 loads the workpiece 3 with two press-fitting holes of different sizes onto the clamping tool 2, and the clamping tool 2 transports the workpiece 3 to the detection tool 5; The pressure plate 12 is slidably mounted on the top of the press block 10. The pressure plate 12 is connected to the press block 10 by a spring 11. The preload force of the spring 11 keeps the pressure plate 12 away from the press block 10. Two pressure rods 13 of different sizes are fixedly mounted on the pressure plate 12. A cavity 15 is provided in the press block 10. A pin slider 16 is slidably mounted in the cavity 15. The pin slider 16 is driven by a cutting cylinder 18 fixedly mounted on the press block 10 to move. Two plug blocks 17 with holes are fixedly mounted in the pin slider 16. The two plug blocks 17 with holes are fixedly mounted. 7 respectively correspond to the two pressure rods 13, and two feeding assemblies 14 are fixedly installed on the press-fitting block 10. The two pressure rods 13 are located between the two feeding assemblies 14, and the two feeding assemblies 14 respectively correspond to the two hole plug blocks 17. The feeding assemblies 14 are used to transport the pins into the hole plug blocks 17. The press-fitting block 10 is provided with two openings 19, both of which are connected to the cavity 15, and the two openings 19 correspond to the two pressure rods 13. When the clamping tool 2 drives the workpiece 3 to move below the press-fitting block 10, the two press-fitting holes on the workpiece 3 correspond to the two openings 19; An alternating opening and closing assembly is provided at the bottom of the pin slider 16. The alternating opening and closing assembly is used to alternately open the through holes at the bottom ends of the two perforated plug blocks 17. When the pin slider 16 is located at one end of the cavity 15, the two perforated plug blocks 17 are aligned with a pressure rod 13 and a feeding assembly 14, respectively. At this time, the alternating opening and closing assembly is activated, so that the through hole at the bottom end of the perforated plug block 17 aligned with the feeding assembly 14 is closed, while the through hole at the bottom end of the perforated plug block 17 aligned with the pressure rod 13 is opened; The press mounting plate 7 is fixedly mounted on the top of the base plate 6. The press mounting plate 7 is located above the press block 10. A servo press 8 is fixedly mounted on the press mounting plate 7. When the servo press 8 is extended, the movable end of the servo press 8 abuts against the press plate 12 and drives the press plate 12 to descend.
[0019] In one case of this embodiment, the driving source can be an electric cylinder, an electric telescopic rod and other components, and other mechanisms that can realize linear reciprocating motion can also be selected. This embodiment is not specifically limited here. It should be noted that the Y-axis servo module 1, loading tooling 4, clamping tooling 2, detection tooling 5, feeding assembly 14, servo press 8 and cutting cylinder 18 described in the present invention are all existing technologies. The present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.
[0020] The working principle of the present invention is as follows: first, the clamping fixture 2 is moved on the Y-axis servo module 1 to one end close to the loading fixture 4 through the driving source, and then the workpiece 3 is placed on the clamping fixture 2 through the loading fixture 4, and the clamping fixture 2 is used to clamp and fix the workpiece 3, and then the clamping fixture 2 is moved between the base plate 6 and the press-fitting block 10. At this time, the two press-fitting holes of different sizes on the clamping fixture 2 correspond to the two openings 19 on the press-fitting block 10 respectively. If the two press-fitting holes of different sizes are 4mm and 8mm respectively, then the thin pressure rod 13, the feeding assembly 14 and the hole plug block 17 all correspond to 4mm pins, and the thick pressure rod 13, the feeding assembly 14 and the hole plug block 17 all correspond to 8mm pins. Figure 6 As shown in the example, at this time, the pin cutting cylinder 18 is retracted, and the pin slider 16 is located at one end of the cavity 15. There are two hole blocks 17 on the pin slider 16. The coarse hole block 17 corresponds to the coarse feeding component 14, while the fine hole block 17, the pressure rod 13 and the 4mm press-fit hole are coaxial. At this time, the 8mm pin is first fed into the coarse hole block 17 through the coarse feeding component 14, and at this time, the alternating opening and closing component closes the bottom through-hole of the coarse hole block 17 and opens the bottom through-hole of the fine hole block 17. At this time, the 8mm pin falls into the coarse hole block 17 and is intercepted by the alternating opening and closing component. Then start the pin cutting cylinder 18 to push the pin slide 16 to the other end of the cavity 15. Figure 7As shown in the figure, the thick plug-in block 17 with holes, the pressure rod 13 and the 8mm press-fit hole are coaxial at this time, and the thin plug-in block 17 with holes corresponds to the thin feeding assembly 14. At this time, by switching the opening and closing components alternately, the through hole at the bottom end of the plug-in block 17 with holes aligned with the feeding assembly 14 is closed, and the through hole at the bottom end of the plug-in block 17 with holes aligned with the pressure rod 13 is opened, that is, the through hole at the bottom end of the thin plug-in block 17 is closed, and the through hole at the bottom end of the thick plug-in block 17 is opened. At this time, the thin feeding assembly 14 delivers the 4mm pin to the thin plug-in block 17 with holes. At the same time, the thick plug-in block 1 The 8mm pin in 7 loses its interception and falls into the 8mm press-fitting hole on the workpiece 3 below. At this time, the servo press 8 is started to press the pressure plate 12 down. At this time, the pressure plate 12 compresses the spring 11 and drives the pressure rod 13 to press down synchronously. The 8mm pin is pressed into the workpiece 3 through the thick pressure rod 13, thereby completing the press-fitting of a press-fitting hole. After the servo press 8 is reset, the spring 11 resets the pressure plate 12, allowing the pressure rod 13 to return to the top of the press-fitting block 10, and then the pin cutting cylinder 18 drives the pin slider 16 to reset in the cavity 15, returning to the position as shown in the figure. Figure 6 The example shown here is a state in which the 4 mm pin in the thin hole insert 17 falls into the 4 mm press-fitting hole on the workpiece 3 below. The servo press 8 is then started, and the 4 mm pin is pressed into the workpiece 3 via the thin pressing rod 13. This completes the press-fitting of two press-fitting holes of different sizes on the workpiece 3. It should be noted that during both press-fitting processes, the other hole insert 17 is pressed into the cavity 15 through the opening 19 and is not blocked by other components.
[0021] In this way, the press-fitting of two pins of different sizes can be achieved at one workstation, reducing one workstation. The pins of different sizes can be moved to the corresponding press-fitting positions by switching the pin slider 16 back and forth in the cavity 15. There is no need to set up two sets of moving mechanisms for pins of different sizes. At the same time, when one pin is press-fitted, the other pin can be loaded synchronously, so that the press-fitting and loading are carried out synchronously, which greatly reduces the press-fitting time of the workpiece 3.
[0022] like Figure 1-Figure 5As shown, as a preferred embodiment of the present invention, the alternating opening and closing component includes a groove 20, a rack plate 21, a gear 22 and a switching component. The groove 20 is opened at the bottom of the pin slider 16, and the two rack plates 21 are slidably installed in the groove 20. The gear 22 is rotatably installed in the groove 20. The gear 22 is located between the two rack plates 21, and the gear 22 is engaged with the two rack plates 21. When the rack plate 21 is located at one end of the groove 20, the through hole at the bottom end of the hole block 17 is opened. When the rack plate 21 is located at the other end of the groove 20, the through hole at the bottom end of the hole block 17 is closed. The switching component is arranged on the press block 10. When the pin slider 16 is located at one end in the cavity 15, the switching component causes a rack plate 21 to move, and the through hole at the bottom end of the hole block 17 aligned with the pressure rod 13 is opened.
[0023] Specifically, the switching assembly includes a circular hole 23 and an opening and closing cylinder 24. Two symmetrically arranged circular holes 23 are opened on the pin slider 16. The two circular holes 23 are both connected to the groove 20, and the two circular holes 23 correspond to the two rack plates 21 respectively. The two opening and closing cylinders 24 are fixedly mounted on the press block 10, and the two opening and closing cylinders 24 are symmetrically arranged. When the pin slider 16 is located at one end in the cavity 15, the movable end of the opening and closing cylinder 24 is aligned with a circular hole 23. At this time, the opening and closing cylinder 24 is started, and the opening and closing cylinder 24 is inserted into the groove 20 through the circular hole 23, pushing the rack plate 21 that blocks the bottom end of the hole plug 17 to the other end.
[0024] In practical application, if Figure 3 As shown in the example, at this time, the two opening and closing cylinders 24 are obviously located on the left and right sides of the press block 10, and as Figure 6 As shown in the figure, in this state, the pin slider 16 corresponds to the opening and closing cylinder 24 on the left. At this time, when the opening and closing cylinder 24 starts to extend, its movable end is inserted into the circular hole 23, thereby pushing the rack plate 21 corresponding to the thin hole plug 17, and pushing the rack plate 21 away from the hole plug 17. At this time, the through hole at the bottom end of the thin hole plug 17 is opened, and when the rack plate 21 moves away, it drives the gear 22 to rotate, and the gear 22 drives the other rack plate 21 to move in the opposite direction, thereby blocking the through hole at the bottom end of the thick hole plug 17, thereby intercepting the pin that falls into the thick hole plug 17. In this way, when the pin slider 16 is moved, the pin in the hole plug 17 always remains stationary in the hole plug 17, avoiding the friction between the pin and the inner wall of the cavity 15 to generate resistance. When the pin slider 16 moves to the other end of the cavity 15, as shown in FIG. Figure 7Taking the example shown, the pin slider 16 corresponds to the opening and closing cylinder 24 on the right. At this time, the opening and closing cylinder 24 extends, which will push the rack plate 21 corresponding to the thick hole plug 17, thereby realizing the opposite movement of the two rack plates 21, and switching the opening and closing of the through holes at the bottom ends of the two hole plugs 17, so that the pin in the hole plug 17 falls into the press-fitting hole on the workpiece 3, and at the same time ensures that the pin loaded into the hole plug 17 can be intercepted by the rack plate 21.
[0025] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, a first magnetic block 25 is fixedly installed at one end of each rack plate 21, and the first magnetic block 25 is located at the end away from the opening and closing cylinder 24. Two second magnetic blocks 26 are fixedly installed on the inner wall of the groove 20, and the two second magnetic blocks 26 are both located in the groove 20 at one end away from the plug-in block with a hole 17, and the second magnetic block 26 is magnetically attracted to the first magnetic block 25.
[0026] Specifically, an end stopper 30 is fixedly installed on both ends of the inner wall of the cavity 15 . When the pin slider 16 moves to one end of the cavity 15 , the pin slider 16 abuts against the end stopper 30 .
[0027] In actual application of this embodiment, when the rack plate 21 is pushed away from the hole plug 17 by the opening and closing cylinder 24, the first magnetic block 25 at one end of the rack plate 21 will attract the second magnetic block 26, thereby ensuring that the two rack plates 21 are stable in the position in the groove 20, avoiding the problem of the two rack plates 21 moving during the movement of the pin slider 16, and when the opening and closing cylinder 24 pushes the rack plate 21 to move, Figure 5 Taking the example shown, although the rack plate 21 on the right is attracted to each other by the first magnetic block 25 and the second magnetic block 26, when the opening and closing cylinder 24 pushes the rack plate 21 on the left, the thrust is transmitted to the rack plate 21 on the right through the gear 22, and the thrust is greater than the attraction of the first magnetic block 25 and the second magnetic block 26, thereby separating the first magnetic block 25 and the second magnetic block 26. Therefore, the first magnetic block 25 and the second magnetic block 26 will not hinder the switching of the states of the two rack plates 21; End limiters 30 are fixedly installed at both ends of the cavity 15. When the pin slider 16 moves to one end of the cavity 15, the pin slider 16 abuts against the end limiter 30. The end limiter 30 can play a limiting role, ensuring that the pin slider 16 moves to the appropriate position, ensuring that the hole plug 17 and the pressure rod 13 and the press-fitting hole on the workpiece 3 are aligned, and at the same time, the movable end of the opening and closing cylinder 24 can be accurately inserted into the circular hole 23.
[0028] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the feeding assembly 14, the plug block with holes 17 and the pressure rod 13 are all detachable, and the opening 19 allows the plug block with holes 17 to pass through.
[0029] In actual application, this embodiment is designed to be detachable by setting the feeding assembly 14, the hole plug 17 and the pressure rod 13. The corresponding feeding assembly 14, the hole plug 17 and the pressure rod 13 can be replaced according to the specific diameters of the press-fitting holes of different sizes on the workpiece 3, so that the feeding assembly 14 and the hole plug 17 accommodate the pins and the press-fitting holes of the same size, and the diameter of the pressure rod 13 is also consistent with the diameter of the pin, and the opening 19 allows the hole plug 17 to pass through, so that the hole plugs 17 with different apertures can be installed in the pin slider 16 through the opening 19.
[0030] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, a positioning sleeve 28 is fixedly installed on the bottom of the press block 10. When the workpiece 3 is located below the press block 10, the positioning sleeve 28 is sleeved on the top of the workpiece 3.
[0031] Specifically, sleeve rods 29 are fixedly installed at the four corners of the bottom of the press block 10. The sleeve rods 29 are sleeved on the support rods 9, and the sleeve rods 29 are slidably connected to the support rods 9. A lifting cylinder 27 is fixedly installed on the base plate 6. When the lifting cylinder 27 is extended, it pushes the press block 10 to rise, and when the movable end of the servo press 8 is retracted, it moves away from the pressure plate 12.
[0032] In actual application of this embodiment, in order to further improve the stability of pressing the pin into the workpiece 3, a pin cutting cylinder 18 is provided at the bottom of the press block 10. First, the press block 10 is pushed up by extending the lifting cylinder 27. At this time, the sleeve rod 29 on the press block 10 will slide on the support rod 9, and the movable end of the servo press 8 will move away from the pressure plate 12 when it shrinks, and the lifting of the press block 10 provides sufficient space. When the press block 10 is lifted, the workpiece 3 is moved to the bottom of the press block 10 by the clamping tool 2, and then the pin cutting cylinder 18 shrinks, and the press block 10 will fall under the action of gravity, and the positioning sleeve 28 will be sleeved on the upper end of the workpiece 3 to position the outer diameter of the workpiece 3, thereby improving the stability of the workpiece 3 during pressing.
[0033] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
