Description

Technical Field

[0001] The utility model relates to the technical field of engine production auxiliary equipment, in particular to a quick-change support and engine tray. Background Art

[0002] With the development of society and the widespread use of automobiles, as a means of transportation, the shape, function and various performance characteristics of automobiles are constantly innovating over time. The engine block is one of the main components inside the car. After the engine block casting is taken out of the furnace, it needs to be air-cooled to reduce the cylinder temperature, and an assembly pallet is needed to transport the engine block.

[0003] There is an existing assembly pallet for supporting the cylinder body, such as the Chinese utility model patent with announcement number CN206732950U, which discloses a pallet device for supporting and assembling the engine. Two oppositely arranged support feet are arranged on the pallet, and a support leg (extension shaft) is arranged on the top of the support foot to support and limit the cylinder body of the engine through the support foot and the support leg.

[0004] Since the engine assembly line is responsible for the mixed assembly of engines of various platforms, the mixed-line production process involves the issue of compatible assembly of pallets. In order to meet production needs, existing assembly pallets are generally designed with multiple types of pallets, and the pallets are manually replaced directly during switching to achieve mixed-line production, which has high usage costs. Some assembly pallets with adjustable legs generally have legs that are slid or bolted. Although they can be changed (adjusted) to accommodate different types of cylinder blocks, their legs are not easy to store when not in operation (they can only be disassembled, which requires high work intensity), and the legs take up a large space, which increases the difficulty of transporting the pallets. Utility Model Content

[0005] In order to solve the technical problems in the above-mentioned background technology that the existing assembly pallet has high use cost and the legs are inconvenient to store, which makes the pallet difficult to transport, the utility model provides a quick-change support and engine pallet.

[0006] The technical solution of this utility model is as follows:

[0007] The utility model provides a quick-change support, including: two relatively arranged mounting seats, each mounting seat has a support leg detachably mounted thereon, the mounting seat including a base and a pressure cover rotatably arranged on the base, the pressure cover being fixed by tightening bolts, a plurality of limiting holes being arranged at intervals along the length direction between the pressure cover and the base, the contour of the limiting hole including an arc segment and a straight line segment, a connecting shaft being fixedly arranged on one side of the bottom of the support leg, the connecting shaft being inserted into the limiting hole, the cross-sectional shape of the connecting shaft and the limiting hole matching, a connecting hole being arranged on the top of the support leg, the support leg being able to adjust its position along the length direction of the mounting seat to meet the support requirements of different cylinder bodies, the support leg being connected to the limiting hole through the connecting shaft, the connecting shaft and the limiting hole both containing an arc segment and a straight line segment, the straight line segment being able to limit its rotation around the axis, when the support leg needs to be stored, the connecting shaft can be rotated around the axis by simply loosening and tightening the bolts, and then the support leg can be laid down for storage, without the need to disassemble the support leg, thereby facilitating operation and reducing space occupation.

[0008] Preferably, the upper part of the base is provided with a plurality of semicircular grooves at intervals along its length direction, and the bottom part of the pressure cover is provided with a plurality of arc grooves at intervals along its length direction. The two sides of the arc grooves are planar structures, and the arc grooves cooperate with the semicircular grooves to form a limiting hole, which can limit the rotation of the connecting shaft around the axis by utilizing the cooperation of the straight line segments. The arrangement of the arc grooves and the semicircular grooves facilitates the rotation of the connecting shaft around the axis in the limiting hole after the pressure cover is loosened.

[0009] Preferably, the curvature of the arc-shaped groove is the same as the curvature of the semicircular groove, so as to facilitate smooth rotation of the connecting shaft.

[0010] Preferably, the length of the connecting shaft is greater than the width of the base, and a baffle is fixedly provided at the end of the connecting shaft, and the axial position of the connecting shaft can be adjusted as needed to further expand the adaptability range.

[0011] Preferably, the baffle is larger than the limiting hole, thereby preventing the connecting shaft from being pulled out axially from the limiting hole.

[0012] Preferably, the top of the support leg is tilted to ensure that it fits closely with the engine support leg to improve support stability.

[0013] Preferably, a handle is installed on the tightening bolt to facilitate the adjustment of the tightening bolt.

[0016] Preferably, a plurality of mounting holes are provided on the tray body, and the bolt holes on the base are fixedly connected to the mounting holes by bolts, so that the position of the base can be adjusted as needed to further improve its adaptability.

[0017] It can be seen from the above technical solutions that the advantages of the utility model are:

[0018] 1. The support leg can be adjusted along the length direction of the mounting base to meet the support requirements of different cylinder bodies. The support leg is connected to the limit hole through a connecting shaft. Both the connecting shaft and the limit hole contain arc segments and straight segments, which can limit their rotation around the axis by using the straight segment.

[0028] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0029] Example 1

[0030] In a typical implementation of the present invention, Figure 1-Figure 4 As shown, a quick-change support is proposed, including: a mounting seat, two mounting seats are provided, the two mounting seats are arranged opposite to each other, and a support foot is detachably mounted on each mounting seat to support and limit the cylinder body and support legs of the engine through the support foot.

[0031] Specific as Figure 2 , Figure 3 As shown, the mounting seat includes a base 1 and a pressure cover 2, the pressure cover 2 is located above the base 1, one end of the pressure cover 2 is hinged to the base 1, and the other end of the pressure cover 2 is fixedly connected to the base 1 by tightening bolts 3, so that when the tightening bolts 3 are loosened, the pressure cover 2 can rotate around the axis to realize the opening of the mounting seat.

[0032] like Figure 3 As shown, the mounting base is provided with a plurality of limit holes 10 at intervals along its length direction. The limit holes 10 are located between the base 1 and the pressure cover 2 and are mainly used for the installation of the support legs. The position of the support legs in the length direction of the mounting base can be adjusted, so that the support can be changed by adjusting the positions of the two support legs to adapt to engine blocks of different sizes.

[0033] The limiting hole 10 is a special-shaped hole structure. The contour of the limiting hole 10 includes an arc segment and a straight line segment. The two sides of the limiting hole 10 are arc segments, and the rest are straight line segments. Figure 3 As shown, a plurality of semicircular grooves are provided at intervals on the upper part of the base 1 along its length direction, and a plurality of arc grooves are provided at intervals on the bottom part of the pressure cover 2 along its length direction. The two sides of the arc grooves are planar structures, the number of the arc grooves is the same as the number of the semicircular grooves and corresponds one to one, and the curvature of the arc grooves is the same as the curvature of the semicircular grooves, so that the limiting hole 10 is formed by the cooperation of the arc grooves and the corresponding semicircular grooves.

[0034] like Figure 2 As shown, in the use state, the two mounting seats are located on the intake and exhaust sides of the cylinder body, wherein the exhaust side support leg 4 is installed on one mounting seat, and the intake side support leg 8 is installed on the other mounting seat, and a connecting shaft 11 is fixedly installed on the bottom side walls of the exhaust side support leg 4 and the intake side support leg 8 respectively, and the connecting shaft 11 is perpendicular to the corresponding support leg, and the exhaust side support leg 4 and the intake side support leg 8 are connected to the limiting holes 10 on the corresponding mounting seats through the connecting shaft 11.

[0035] like Figure 3 As shown, the cross-section of the connecting shaft 11 is a special-shaped structure. The cross-sectional shape of the connecting shaft 11 is the same as and matches the limiting hole 10. The cross-sectional shape of the connecting shaft 11 also includes an arc segment and a straight segment. After the connecting shaft 11 is inserted into the limiting hole 10, the connecting shaft 11 can be limited to rotate around the axis with the cooperation of the straight segment, thereby ensuring the vertical fixation of the exhaust side support leg 4 and the intake side support leg 8. When the exhaust side support leg 4 and the intake side support leg 8 need to be folded down and stored, only the tightening bolt 3 needs to be loosened to change the size of the limiting hole 10 (the clamping force of the pressure cover 2 is reduced), thereby eliminating the contact between the connecting shaft 11 and the straight segment on the limiting hole 10. The connecting shaft 11 can rotate around the axis to realize the rapid folding and storage of the exhaust side support leg 4 and the intake side support leg 8, reducing the space occupied by the support legs during non-working periods and facilitating the transportation of the pallet.

[0036] Since the mounting base is provided with a plurality of limit holes 10 at intervals along its length direction, the exhaust side support leg 4 and the intake side support leg 8 can be adjusted along the length direction of the mounting base as needed to achieve rapid changeover and meet different production requirements. There is no need to equip pallets and support legs of different sizes, which effectively reduces the cost of use.

[0037] The length of the connecting shaft 11 is greater than the width of the base 1, and a baffle 12 is fixedly provided at the end of the connecting shaft 11 (the end away from the corresponding support foot). The baffle 12 is a circular plate structure, and the size of the baffle 12 is greater than the limiting hole 10 to prevent the connecting shaft 11 from being pulled out from the limiting hole 10 along the axial direction. Since the length of the connecting shaft 11 is greater than the width of the base 1, in this embodiment, the length of the connecting shaft 11 is 20 mm larger than the width of the base 1, so that the position of the connecting shaft 11 can be adjusted along the axial direction, and then the position of the corresponding exhaust side support foot 4 and the intake side support foot 8 can be adjusted to further improve the adaptability of the quick-change support.

[0038] The tops of the exhaust side support leg 4 and the intake side support leg 8 are both provided with connecting holes for connecting with the first connecting bolt 5. The intake side of the cylinder body is installed with the intake side support leg 9, and the exhaust side of the cylinder body is installed with the exhaust side support leg 6. One end of the exhaust side support leg 6 is connected to the top connecting hole of the exhaust side support leg 4 through the first connecting bolt 5, and the other end is fixedly connected to the exhaust side of the cylinder body through the second connecting bolt 7; one end of the intake side support leg 9 is connected to the connecting hole on the top of the intake side support leg 8 through the first connecting bolt 5, and the other end is fixedly connected to the intake side of the cylinder body through the second connecting bolt 7.

[0039] It can be understood that the intake side support leg 9 and the exhaust side support leg 6 mentioned in the present embodiment are both connecting parts between the engine and the vehicle body during actual assembly, and do not belong to the structural part of the quick-change type support in the present embodiment. Due to the different cylinder body structures, the lengths and installation positions of the intake side support leg 9 and the exhaust side support leg 6 are also different. Therefore, in the present embodiment, the exhaust side support leg 4 and the intake side support leg 8 are arranged to be position-adjustable to meet the support requirements of intake side support legs 9 and exhaust side support legs 6 of different lengths and positions.

[0040] In order to ensure stable support for the air intake side support leg 9 and the exhaust side support leg 6, the tops of the exhaust side support leg 4 and the air intake side support leg 8 are tilted. In this embodiment, the tilt is 3.1° to fully fit with the 3.1° plane of the product support leg.

[0041] In order to improve the convenience of using the tightening bolt 3, a handle is provided on the tightening bolt 3 to facilitate manual adjustment of the tightening bolt 3.

[0042] The specific working principle is:

[0043] The cylinder body is fixedly connected with the intake side leg 9 and the exhaust side leg 6. After the cylinder body is assembled, the exhaust side leg 4 and the intake side leg 8 are installed according to the actual length and position of the intake side leg 9 and the exhaust side leg 6;

[0044] When installing the exhaust side support leg 4 and the intake side support leg 8, loosen the tightening bolts 3 on the corresponding mounting seat, open the pressure cover 2, insert the connecting shaft 11 into the limiting hole 10 at the corresponding position, buckle the pressure cover 2 and then adjust the axial position of the connecting shaft 11, so that the installation position of the exhaust side support leg 4 and the intake side support leg 8 meets the support requirements of the intake side support leg 9 and the exhaust side support leg 6, tighten the tightening bolts 3, use the pressure cover 2 to press the connecting shaft 11 to limit its position, and limit the axial rotation of the connecting shaft 11 under the cooperation of the limiting hole 10 and the straight section on the connecting shaft 11;

[0045] Use the first connecting bolt 5 to fix the intake side leg 9 and the exhaust side leg 6 on the corresponding exhaust side leg 4 and intake side leg 8;

[0046] When the exhaust side support leg 4 and the intake side support leg 8 need to be stored, loosen and tighten the bolt 3, and directly apply force to make the exhaust side support leg 4 and the intake side support leg 8 rotate around the connecting shaft 11 so that they can be folded down for storage. After tightening the bolt 3, the exhaust side support leg 4 and the intake side support leg 8 are restricted from continuing to rotate, thereby reducing the space occupied in the non-working state and facilitating transfer.

[0047] like Figure 3 As shown, a bolt hole 101 is also provided at the bottom of the base 1 so as to fix the base 1 on the pallet by bolt connection.

[0048] Example 2

[0049] In another typical embodiment of the utility model, an engine tray is proposed, including a tray body and the quick-change support mentioned in Example 1, and a plurality of mounting holes are opened on the tray body for installing bolts, and the bolts are connected to the bolt holes 101 on the base 1, so as to realize the fixed installation of the base 1 on the tray body.

[0050] Since a number of mounting holes are provided on the tray body, the position of the base 1 can be adjusted as needed to further improve its adaptability. Combined with the use of the position-adjustable exhaust side support feet 4 and the intake side support feet 8, the engine tray in this embodiment has a strong overall adaptability and can be suitable for the production needs of engines of different sizes. In addition, the overall structure is simple, the use cost is low, and it is easy to operate.

[0051] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
