Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts and inspection tools, and particularly to an air compressor main bracket and an inspection tool specifically used for detecting the air compressor main bracket. Background Art

[0002] The air compressor main bracket is a commonly used automotive part, which mainly installs and supports the air compressor in the vehicle. When installing the air compressor, a compressor is also fixed on its side. Since the existing air compressor main brackets are mainly used for installing and fixing the air compressor, and the installation of the compressor must use other parts for installation and fixing, this increases the production process and the number of parts, and also increases the production cost for enterprises.

[0003] The general structure of the existing air compressor main bracket is as Figure 1 shown. It is mainly composed of two A plates and B plates arranged at a 90-degree angle. The design of this structure originated from foreign automotive companies, that is, the design of this mechanism was carried out by foreign technicians. However, this structure of the air compressor main bracket is mainly used for pickup trucks. Due to the complex road conditions in China, pickup trucks are mainly used for carrying goods, which is different from foreign family cars. Especially for pickup trucks running on mountain roads, the strength of the air compressor main bracket is not high, the service life is extremely short, and the air compressor main bracket often breaks, resulting in a low service life of the air compressor main bracket and an increase in vehicle failure rate. Therefore, the existing Figure 1 structure of the air compressor main bracket shown does not adapt to the national conditions of China and needs to be improved in design.

[0004] Furthermore, in the production and manufacturing of the existing air compressor main bracket, due to the asymmetric position of the B holes on the B plate, it is not easy to fix during processing operations such as grinding and punching, and it often shakes and loosens. In order to fix it well, pads need to be added during processing, which is tantamount to increasing the manufacturing process, reducing production efficiency, and is also not conducive to the control of product quality. Summary of the Invention

Detailed implementation mode

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0050] Embodiment 1: A main bracket of an air compressor, see Figures 1 to 8 ;

[0051] It includes two L-shaped A plates A and B plates B. At the corners of the A plates, there are A holes 101 and 102 for installing components. At one corner of the outer end of the B plate, there is a B hole 201 for fixing. At the openings at both ends of the A holes and B holes, there are respectively annular steps 103, and the annular steps 103 are higher than the inner side surface / outer side surface of the A plate / B plate; precisely due to the existence of this annular step 103, it is not easy to fix and support the B plate during operations such as turning and milling. To solve this problem in this design, a protrusion 601 is provided at the outer side corner of the inner end of the B plate in the diagonal direction of the B hole. The end of the protrusion 601 is a plane and is at the same horizontal plane as the annular step at the end of the B hole on the outer side surface of the B plate. This protrusion 601 is integrally formed with the B plate, so that the B plate can be supported by this protrusion during processing to avoid the occurrence of the problem of unbalanced two-point support.

[0052] To increase the strength of the main bracket of this air compressor, the included angle a between the A plate and the B plate in this design is 80° - 89°; preferably, the included angle between the A plate and the B plate is 83° - 86°; specifically, it can be 83°, 85° or 86°. In this way, the A plate and the B plate form an acute angle, increasing the tensile strength in the reverse direction of the A plate and the B plate.

[0053] Further, the present design also provides an arc-shaped groove 120 in the middle of the A plate. The arc-shaped groove 120 extends from the middle of the A plate to the outer end of the A plate and passes through the outer end of the A plate. The A holes 101 at the two corners of the outer end of the A plate are respectively located on both sides of the end of the arc-shaped groove. The A holes 101 on this A plate are mainly used to install the bearing seat. Through this arc-shaped groove 120, the bottom of the housing for installing the bearing on the bearing seat can be accommodated, avoiding the way of simply increasing the height of the A hole 101 in the prior art. Compared with the above method, this design not only reduces the space volume occupied during the whole installation, but also increases the overall strength and stability, and avoids the occurrence of fracture caused by simply increasing the height of the A hole 101.

[0054] Further, the present design also provides an outer fixing plate 403 on the outer side surface of the A plate. The outer fixing plate 403 is perpendicular to the outer side surface of the A plate. The outer fixing plate 403 is provided with outer fixing holes 404 arranged along the length direction of the outer fixing plate; the outer fixing plate 403 is in an arc shape bent towards the A plate in the middle, and the outer fixing holes 404 are in an arc shape and have the same radian as the outer fixing plate. At the same time, the lower end 130 of the outer fixing plate extends downward to the plane below the outer side surface of the B plate, and a side fixing hole 131 is provided at the lower end of the outer fixing plate. A notch 132 communicating with the outer fixing hole is provided on the side wall of the side fixing hole. A diagonal tension plate 401 is also connected between the A plate and the B plate on the same side as the B hole. The diagonal tension plate 401 is provided with rectangular holes 404 arranged along the length direction of the diagonal tension plate; the combined design of the outer fixing plate 403 and the diagonal tension plate 401 increases the overall strength of the bracket in terms of structure. At the same time, the compressor can be installed and fixed on the outer fixing plate 403 and the diagonal tension plate 401, realizing the dual functions of fixing and installing the air compressor and the compressor with one bracket, and solving the problem that additional components are required for installing the compressor, increasing the number of components.

[0055] Further, the present design also provides a C-shaped notch 501 and 502 at the corner of the A plate and the corner of the B plate where the diagonal tension plate 401 is located respectively; these C-shaped notches 501 and 502 are of great significance for reducing the weight of the whole bracket and strengthening the strength of the bracket.

[0056] Further, the present design also provides criss-crossing reinforcing ribs 121 and 220 on the inner side surface of the B plate and the outer side surface of the A plate respectively.

[0057] Further, for better fixing of the B plate, the present design provides an ear 202 on the outer end of the B plate and in the direction opposite to the B hole. The ear 202 is provided with a fixing hole 203. Preferably, the fixing hole is in an elliptical shape.

[0058] Example 2, see Figures 9 to 11 , this embodiment discloses a fixture specifically used for detecting the main bracket of an air compressor.

[0059] Specifically, it includes a support rod 801 with its lower end inserted into hole A / hole B. A horizontal pipe 806 is provided at the top end of the support rod 801, and the horizontal pipe 806 is rotatably connected to the top end of the support rod 801. Specifically, a bearing 805 is sleeved on the top end of the support rod 801, a sleeve 804 is sleeved on the bearing 805, and the horizontal pipe 806 is fixed to the top end of the sleeve 804.

[0060] It further includes a cross bar 807. One end of the cross bar 807 is movably inserted into the horizontal pipe 806, and a scale 808 is provided on the cross bar 807. A vertical pipe 809 is fixed to the other end of the cross bar 807. A vertical rod 812 is movably inserted into the vertical pipe 809, and a hole measuring head 815 is detachably installed at the lower end of the vertical rod 812.

[0061] Specifically, an annular retaining ring 810 and 811 are respectively provided at both ends of the vertical pipe. The vertical rod passes through the two annular retaining rings 810 and 811, and a top plate 813 is provided on the vertical rod located inside the vertical pipe. A spring 814 is sleeved on the vertical rod located inside the vertical pipe. The lower end of the spring abuts against the annular retaining ring at the lower end of the vertical pipe, and the upper end of the spring abuts against the top plate and applies an elastic force to the top plate.

[0062] In this design, the axis of the support rod is parallel to the axis of the vertical rod, and the axes of the support rod, the vertical rod, and the cross bar are located in the same plane.

[0063] Further, the hole measuring head 815 is threadedly connected to the vertical rod. A retaining ring 817 is provided in the middle of the hole measuring head, and the lower end 816 of the hole measuring head is in a spherical arc shape.

[0064] Further, a rectangular opening 818 is formed in the top side wall of the horizontal pipe 806. An arrow 819 extending towards the inside of the rectangular opening is provided in the middle of the side of the rectangular opening. The front tip of the arrow 819 is located on the axis of the support rod.

[0065] Further, the lower edge 813 of the support rod is arc-shaped, and a stopper 802 is provided on the support rod near the end of the lower end of the support rod. The stopper extends outward in one direction on the horizontal plane, and the scale is also provided on the vertical rod.

[0066] When the inspection tool of this design inspects each hole B on the B plate, reference can be made to Figure 11, during use, the lower end of the support rod is inserted into one of the B holes, then the cross bar is rotated so that the vertical rod at the front end of the cross bar is located above the other B holes, and then the vertical rod is pressed downwards to insert the measuring hole head at the lower end of the vertical rod into the B hole to be measured. It can be known whether the aperture of the B hole to be measured meets the requirements through the measuring hole head. At the same time, the distance between the centers of the two B holes can be obtained through the scale on the cross bar. If it is necessary to determine whether the B hole to be measured and the B hole into which the support rod is inserted are in the same plane, at this time, the cross bar is retracted, and then the lower end of the measuring hole head is abutted against the forward extending stopper and the scale H on the vertical rod is noted (the top end of the vertical tube can be used as a reference point). The thickness of the stopper is the known thickness I. Then the cross bar is stretched forward, and then the lower end of the measuring hole head is abutted against the annular step at the end of the B hole to be measured and the scale H' on the vertical rod is checked. If H' = H + I, it means that the two B holes are in the same horizontal plane. If H' is different from H + I, it means that they are not in the same plane. In this way, the aperture of each B hole on the B plate, the distance between any two B holes, and the height of the B hole can be detected.

[0067] Similarly, the aperture of the A holes on the A plate, the distance between any two A holes, and the height of the A holes can be detected by the above method.

[0068] Similarly, by the above method, with the lower end of the support rod inserted into the side fixing hole, the outer fixing hole, the width and the distance of the rectangular hole can be detected.

[0069] The embodiments disclosed in the present invention are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
