Description

Technical Field

[0001] The utility model relates to the technical field of compressor manufacturing, in particular to a compressor front cover pressing pin device. Background Art

[0002] The automotive air-conditioning compressor is the heart of the electric vehicle air-conditioning refrigeration system, which plays the role of compressing and transporting refrigerant vapor. During the assembly process of the electric vehicle air-conditioning compressor, pins need to be installed on the front cover. In the traditional processing method, manual pressing of the pins is mostly used, and the processing efficiency is low;

[0003] In the related art, in order to further improve efficiency, a fully automatic or semi-automatic method is often used. For example, the fully automatic method can clamp the pin by a manipulator, locate the pin hole by a visual recognition device at the end of the manipulator, and then press the pin in. The semi-automatic method is to manually place the pin in the pin hole of the front cover, and then press the pin in by an automatic crimping device.

[0004] However, the inventors found that the above-mentioned fully automatic robot pinning method is costly, and the robot is easily damaged during the pressing process, and the cost of subsequent maintenance is high; while the method of manually placing pins, on the one hand, the processing efficiency is not greatly improved, and on the other hand, mechanical pressing also affects the personal safety of the staff.

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] like Figures 1 to 8 The compressor front cover pin pressing device shown in the figure comprises: a front cover driving mechanism 1, a pin pressing mechanism 2, a pin conveying mechanism 3 and a pin feeding mechanism 4, wherein Figure 1 As shown in the figure, the front cover driving mechanism 1 includes a front cover placement seat 11 and a rotation driving member 12 connected to the front cover placement seat 11 for driving the front cover placement seat 11 to rotate a set angle;

[0034] The pressing mechanism 2 is arranged opposite to the front cover driving mechanism 1, and includes a pressing member 21 arranged toward the front cover placement seat 11 and a pressing member driving member 22 connected to the pressing member 21 for driving the pressing member 21 to move toward or away from the front cover placement seat 11;

[0035] The pin transmission mechanism 3 is arranged on one side of the front cover driving mechanism 1, and includes a pin clamping assembly 31 and a transmission driving member 32 connected to the pin clamping assembly 31 and used to drive the pin clamping assembly 31 to move above the front cover placement seat 11 toward or away from the front cover placement seat 11;

[0036] The pin feeding mechanism 4 includes a vibration plate 41 disposed on one side of the pin conveying mechanism 3 and a material storage assembly 42 connected to the discharge port of the vibration plate 41;

[0037] Among them, the pin clamping assembly 31 is configured to take out the pins from the material storage assembly 42 and transfer them to between the front cover placement seat 11 and the pin pressing member 21. The pin pressing member 21 is configured to press the pins on the pin clamping assembly 31 into the pin holes of the front cover when the rotating driving member 12 moves the front cover to a set angle.

[0038] When performing the pin pressing operation, first, the vibration plate 41 in the pin feeding mechanism 4 transfers the pin to the pin conveying mechanism 3 by vibration, and a pin is clamped to the top of the front cover driving mechanism 1 by the pin clamping assembly 31 on the pin conveying mechanism 3. At this time, the rotating driving member 12 in the front cover driving mechanism 1 has rotated the front cover to the pin hole on the front cover corresponding to the current position of the pin, and is also on the same vertical line with the pin pressing member 21 in the pin pressing mechanism 2. Finally, the pin pressing driving member 22 drives the pin pressing member 21 to fall, so that the pin pressing member 21 presses the pin into the front cover.

[0039] In the above embodiment, the pin feeding mechanism 4 transmits the pin to the storage assembly 42, so that the pin clamping assembly 31 in the pin transmission assembly clamps the pin and moves it to the position corresponding to the front cover on the front cover placement seat 11, and finally the pin is pressed into the front cover by the pin pressing mechanism 2. Through the above arrangement, the automation of the pin pressing of the compressor front cover is realized, which improves the efficiency compared with the manual placement method in the prior art, and reduces the cost compared with the robot method in the prior art.

[0040] Based on the above embodiment, the specific structure of the front cover placement seat 11 is as follows: Figure 2 As shown in , the front cover placement seat 11 includes a base 11a, a rotating drum 11b rotatably connected to the base 11a, a positioning column 11c corresponding to the front cover connecting ear, and a rotating driving member 12 connected to the rotating drum 11b. Through such an arrangement, when placing the front cover, the front cover can be positioned by simply inserting the hole on the connecting ear on the front cover into the column positioning column 11c. In some embodiments of the utility model, the rotating driving member 12 can be a stepping motor or a reduction motor.

[0041] In some embodiments of the present invention, in order to adjust the position of the base 11a in the lateral direction, the lateral direction, i.e. Figure 2 In the left and right directions, the front cover placement seat 11 also includes a base plate 13, and the base plate 13 has a horizontally arranged straight hole 13a, and the base 11a is connected to the base plate 13 through the straight hole 13a. Through the arrangement of the straight hole 13a, the fixed position of the base 11a on the base plate 13 can be appropriately adjusted in the horizontal direction. Specifically, the base 11a can be fixed by bolts and nuts. When adjustment is required, the bolts can be loosened to adjust the position of the base 11a. Further, in order to ensure that the position of the base 11a does not shift when adjusting, please continue to refer to Figure 2 The base plate 13 has a stopper 14, which is parallel to the straight hole 13a and is arranged on both sides of the base 11a. The base plate 13 also has an adjustment member 15 for adjusting the lateral position of the base 11a. The adjustment member 15 here refers to a device for moving the base 11a in the lateral direction, which can be achieved by screwing bolts to adjust the offset distance of the base 11a, or can adopt other structural forms such as hydraulic cylinders. The setting of the stopper 14 ensures the straightness of the base 11a during the movement, avoids the deflection of the base 11a during the movement, and improves the reliability of position adjustment.

[0042] Based on the above embodiments, Figure 3 and Figure 4 As shown in , the material storage component 42 includes a pin seat 42a, a pin seat 42a, and a pin channel 42b which is set up to pass through from top to bottom. The pin also has two longitudinally arranged pin locking members 42c on it, and the pin locking member 42c has a pin 42c1 which is connected to the pin channel 42b and can extend into the pin channel 42b and abut the pin. The pin seat 42a is arranged below the vibration disk 41, and a connecting pipe 41a is provided between the vibration disk 41 and the pin seat 42a. By arranging the pin seat 42a below the vibration disk 41, the connecting pipe 41a is connected to the pin seat 42a in a nearly vertical direction, and the small Ding that falls from the vibration disk 41 also falls into the pin seat 42a in a nearly vertical state when passing through the connecting pipe 41a. The pin locking member 42c here is used to temporarily fix the pin in the pin channel 42b to prevent the pin from accidentally falling off from the pin seat 42a; as shown in FIG. Figure 4 As shown in the figure, when the pins are discharged, the lower pin locking member 42c first releases the clamped pin, and the upper pin locking member 42c still keeps locking the upper pin. This arrangement can ensure that only one pin falls from the pin channel 42b each time; it should be pointed out here that the pin locking member 42c can be a cylinder or oil cylinder structure.

[0043] Please refer to Figure 5 and Figure 6 In some embodiments of the present invention, a receiving seat is provided below the pin seat 42a. The receiving seat has an L-shaped cross section and is used to receive the pin dropped from the pin seat 42a. There is a space between the bottom of the pin seat 42a and the receiving seat for the pin clamping assembly 31 to move. By providing the receiving seat, the pin can be prevented from falling off. Figure 6 As shown in , there is also a transverse groove on the transverse receiving surface of the receiving seat for placing the pins that are not successfully clamped.

[0044] The specific structure of the pin clamping assembly 31 is as follows Figure 7As shown in , the pin clamping assembly 31 includes a cylinder clamping jaw 31a, a top plate 31b fixed on the cylinder clamping jaw 31a, and a fixed cylinder 31c fixed on the top plate 31b. The fixed cylinder 31c has two clamping windows 31c1 arranged opposite to each other, and the clamping claw of the cylinder clamping jaw 31a extends into the clamping window 31c1. In this way, when the top plate 31b moves to the position where the fixed cylinder 31c is aligned with the pin channel 42b, the pin detached from the pin seat 42a can enter the fixed cylinder 31c and maintain the vertical state of the pin. The clamping claw of the cylinder clamping jaw 31a extends into the clamping window 31c1 to fix the pin in the fixed cylinder 31c; in some embodiments of the present utility model, please refer to Figure 8 The fixed cylinder 31c also has a through hole 31c2 that penetrates radially, and a laser sensor 31d that is used to pass through the through hole 31c2 is fixed on the top plate 31b. The laser sensor 31d is used to detect whether a pin has fallen into the fixed cylinder 31c. When the laser is blocked, it means that a pin has entered the fixed cylinder 31c. At this time, the cylinder clamp 31a is driven again, so that the clamping claw on the cylinder clamp 31a extends into the clamping window 31c1 to fix the pin inside. Through the above arrangement, the pin clamping assembly 31 works more reliably.
