Description

Technical Field

[0001] The utility model relates to the technical field of automobile compressors, in particular to a cylinder pin pulling machine for an automobile air-conditioning compressor. Background Art

[0002] The automobile air conditioning compressor is the heart of the automobile air conditioning refrigeration system, playing the role of compressing and transporting refrigerant vapor. Compressors are divided into two types: fixed displacement and variable displacement. According to different working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors. However, it has always been a difficult problem to remove the positioning pins during cylinder overhaul.

[0003] The patent CN 211362103 U with publication number discloses a pin pulling machine for automobile air-conditioning compressor cylinder body, which includes a supporting frame, a clamping mechanism composed of a movable jaw and a fixed jaw, a first power device, a second power device, a push rod and a push block sleeved on the end of the push rod, as well as a shift rod, a shift fork and a support. The pin pulling machine for automobile air-conditioning compressor cylinder body clamps the positioning pin on the automobile air-conditioning compressor cylinder body through the clamping mechanism, and applies a thrust parallel to the positioning pin body to the automobile air-conditioning compressor cylinder body with the help of the push rod and the push block, so that the positioning pin on the automobile air-conditioning compressor cylinder body and the positioning pin connected thereto are separated from each other. However, the position of the semicircular grooves on the fixed jaw and the movable jaw of the device are fixed. Even if multiple semicircular grooves are provided, the position distance between the positioning pins on all cylinder bodies on the market may not be fully satisfied, thereby reducing the applicability of the compressor cylinder body pin pulling machine. Therefore, an automobile air-conditioning compressor cylinder body pin pulling machine is proposed to solve the problem that the existing pin pulling machine cannot adjust the pin pulling position according to the position of the cylinder body positioning pin.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1-4 A pin pulling machine for a cylinder block of an automobile air-conditioning compressor comprises a pin pulling seat 1, adjusting notches 14 are provided on both sides of the top of the pin pulling seat 1, an adjusting seat 2 is provided in the inner cavity of the adjusting notch 14, a clamping block 3 is relatively provided on the top of the adjusting seat 2, a clamping groove 4 is provided on the top of the clamping block 3, an adjusting groove 5 is provided on the inner cavity wall of the adjusting notch 14, an adjusting block 6 is provided in the inner cavity of the adjusting groove 5, a slide groove 7 is provided on the top of the adjusting seat 2, a slider 8 is provided in the inner cavity of the slide groove 7, fastening mechanisms 9 are relatively provided at both ends of the top of the pin pulling seat 1, and an ejection mechanism 10 and a discharge mechanism 13 are provided in the inner cavity of the pin pulling seat 1.

[0024] Furthermore, the adjustment block 6 is fixedly connected to the adjustment seat 2, and there is a friction force between the adjustment block 6 and the adjustment groove 5 that can make the adjustment seat 2 stationary. The slider 8 is fixedly connected to the clamping block 3. After adjusting the position of the adjustment seat 2, the position of the adjustment seat 2 is automatically limited by the friction force between the adjustment block 6 and the adjustment groove 5, that is, the positioning pin can be clamped in cooperation with the fastening mechanism 9 under the restriction of the longitudinal position of the clamping block 3 by the slider 8 in the groove 7.

[0025] Furthermore, the fastening mechanism 9 includes a top fixing plate 91 fixedly connected to the pin pulling seat 1, and the adjacent ends of the two fixing plates 91 are fixedly connected with an electric push rod 92, and one end of the electric push rod 92 is fixedly connected with a fastening plate 93, the fastening plate 93 is in contact with the clamping block 3 but not fixed, and the adjacent end surfaces of the two fastening plates 93 are relatively rough. The fastening plate 93 in the fastening mechanism 9 is in contact with the clamping block 3 but not fixed, so that the adjustment seat 2 can freely adjust the spacing, and the electric push rod 92 on the fixing plate 91 can make the clamping block 3 close to clamp the positioning pin, which is convenient for the subsequent removal of the positioning pin.

[0026] Furthermore, the ejection mechanism 10 includes an electric telescopic rod 101 fixed in the inner cavity of the pin pulling seat 1, a slot 102 is provided at the top of the pin pulling seat 1, and an ejection block 103 is provided in the inner cavity of the slot 102, and the ejection block 103 is fixed to the electric telescopic rod 101. When the locating pin is clamped, turning on the electric telescopic rod 101 can drive the ejection block 103 in the slot 102 to move up to contact with the cylinder body and then lift the locating pin out of the cylinder body, completing the pin pulling, thereby improving the convenience of pulling out the locating pin.

[0027] Furthermore, a marking line 11 is provided at the middle position of the top of one end of the adjustment seat 2, and a scale 12 is provided at the top of the pin pulling seat 1. The marking line 11 is aligned with the zero scale of the scale 12 and the center line of the clamping groove 4. The distance between the marking lines 11 on the two adjustment seats 2 is a known determined value. The distance between the locating pins can be determined based on the position of the marking line 11 on the adjustment seat 2 at the scale 12, and then the sum of the spacing between the two marking lines 11 is added, which is the spacing between the locating pins. This facilitates precise control of the lateral distance between the two pairs of clamping blocks 3 on the adjustment seat 2 to be the same as the spacing between the locating pins, and facilitates the subsequent fixing and clamping of the locating pins.

[0028] Furthermore, the discharge mechanism 13 includes two fixing seats 131 relatively fixed on both sides of the electric telescopic rod 101 , a slot hole is provided through the middle of the top of the adjustment seat 2 , and a guide groove 132 is provided on the top of the fixing seat 131 .

[0029] Furthermore, discharge slots 133 are formed on both sides of the pin pulling seat 1, and a collection box 134 is fixed to the bottom of the discharge slots 133. When the locating pin on the cylinder body is pulled out, it will fall from the slot on the adjustment seat 2 into the guide slot 132 in the fixed seat 131 in the pin pulling seat 1. Under the action of the inclined guide slot 132, the locating pin will move directly from the discharge slot 133 to the collection box 134, thereby improving the convenience of collecting the locating pins dropped by the pin pulling machine.

[0030] Working principle: When using this automobile air-conditioning compressor cylinder pin pulling machine, according to the distance between the locating pins on the cylinder body to be pulled out, use the adjustment block 6 in the adjustment groove 5 to adjust the distance between the clamping blocks 3 on the top of the adjustment seat 2 in the adjustment groove 14, and then place the locating pins between the opposite clamping grooves 4 respectively, use the fastening mechanism 9 to cooperate with the slider 8 in the slide groove 7 so that the locating pins are clamped by the clamping blocks 3, and then use the ejection mechanism 10 to push the cylinder body upward to make the locating pins detach from the cylinder body, thereby solving the problem that the existing pin pulling machine cannot adjust the pin pulling position according to the position of the cylinder body locating pin.
