Description
Technical Field
[0001] This utility model relates to the field of tractor engine assembly for supporting tooling, and more particularly to an engine assembly for supporting tooling. Background Technology
[0002] Tractor engine assembly support fixtures are key equipment for ensuring engine production, assembly, maintenance, transportation, and storage. Currently, there are a wide variety of tractor engine models. Existing fixtures are mostly custom-designed and only compatible with specific engine models. When switching engine models or dealing with improved engines, new fixtures need to be manufactured, resulting in high equipment costs, large inventory pressure, and difficulty in meeting the diverse, small-batch production needs of the tractor industry.
[0003] While existing engine assembly support fixtures, through their structural design tailored to specific engine models and offering high positioning accuracy, can ensure stability during assembly and testing and reduce errors, they face numerous prominent problems in practical use. In terms of specific operation, most support fixtures are designed for specific engine models and can only match the dimensions and weight of a single engine. When the engine model is changed, the old fixtures cannot be reused and must be redesigned and manufactured, resulting in high fixture idle rates and wasted equipment costs. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative engine assembly support fixture to solve these problems. Summary of the Invention
[0004] The purpose of this utility model is to provide an engine assembly for supporting tooling, which solves the problem that most supporting tooling is only compatible with the size and weight of a single engine model. When the engine model is changed, the old tooling cannot be reused and needs to be redesigned and manufactured, resulting in high tooling idle rate and waste of equipment costs.
[0005] To achieve the above objectives, this utility model provides an engine assembly for supporting tooling, including an adjustment component.
[0006] It also includes a strip base plate in the adjustment assembly, on the upper surface of which a strip mounting plate is movably connected, and an inverted shell is fixedly connected to the side surface of the strip mounting plate.

An extension plate is fixedly connected to the upper surface of the connecting block.
[0007] The mounting block is internally fixedly connected to a connecting rod, and rollers are rotatably connected to the two end surfaces of the connecting rod. The side surfaces of the rollers roll on the upper surface of the strip-shaped base plate. The upper surface of the strip-shaped mounting plate is provided with mounting holes, and the mounting holes on the strip-shaped mounting plate correspond one-to-one with the mounting holes on the strip-shaped base plate.
[0008] The connecting block and the extension plate are fixedly connected by auxiliary support rods. There are four auxiliary support rods, and the positions of two auxiliary support rods on the same side are corresponding.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0021] Please see Figures 1-5 An engine assembly for supporting tooling includes an adjustment component 1.
[0022] It also includes a strip base plate 101 in the adjustment assembly 1. A strip mounting plate 102 is movably connected to the upper surface of the strip base plate 101. An inverted shell 104 is fixedly connected to the side surface of the strip mounting plate 102. A central partition 107 is fixedly connected to the inner wall of the inverted shell 104. An electric telescopic rod 108 is fixedly connected to the side surface of the central partition 107. An installation block 109 is fixedly connected to the output end of the electric telescopic rod 108. A connecting block 113 is fixedly connected to the upper surface of the installation block 109. An extension plate 106 is fixedly connected to the upper surface of the connecting block 113.
[0023] In the adjustment assembly 1, the strip base plate 101 is the basic support component, and the strip mounting plate 102 connected above it can be moved laterally along the base plate. The inverted shell 104 on the side surface of the strip mounting plate 102 supports the electric telescopic rod 108 through the central partition 107 fixed on the inner wall. The output end of the telescopic rod is connected in sequence to the mounting block 109, the connecting block 113 and the extension plate 106, forming a "power-transmission-execution" link. During operation, the electric telescopic rod 108 extends and retracts, driving the extension plate 106 to move horizontally. In conjunction with the sliding of the strip mounting plate 102, the support position can be adjusted in two dimensions to adapt to engines with different lateral dimensions and support point layouts.
[0024] Furthermore, a connecting rod 110 is fixedly connected inside the mounting block 109. Rollers 111 are rotatably connected to the two end surfaces of the connecting rod 110. The side surfaces of the rollers 111 roll on the upper surface of the strip base plate 101. The upper surface of the strip mounting plate 102 has mounting holes 103, which are located on the upper surface of the strip base plate 101. The mounting holes 103 on the strip mounting plate 102 and the strip base plate 101 correspond one-to-one. The connecting rod 110 fixed inside the mounting block 109 is rotatably connected to the rollers 111 at both ends. The rollers 111 roll in contact with the upper surface of the strip base plate 101, converting the sliding friction of the strip mounting plate 102 into rolling friction, reducing the adjustment resistance. The mounting holes 103 on the strip mounting plate 102 and the strip base plate 101, which correspond one-to-one, are positioned by inserting fasteners to achieve rigid locking after adjustment, ensuring support stability.
[0025] Furthermore, four auxiliary support rods 114 are fixedly connected between the connecting block 113 and the extension plate 106, with two auxiliary support rods 114 on the same side corresponding to each other. The four auxiliary support rods 114 between the connecting block 113 and the extension plate 106 are symmetrically distributed, with two corresponding to each other on the same side, forming a triangular stable support structure. This enhances the connection strength between the connecting block 113 and the extension plate 106, prevents the extension plate 106 from deforming under stress, and improves its load-bearing capacity.
[0026] Furthermore, a complementary plate 112 is fixedly connected to the inner surface of the extension plate 106. There are two extension plates 106 and two complementary plates 112, evenly distributed and corresponding in position. Two inverted L-shaped limiting plates 105 are slidably connected to the front and rear surfaces of the extension plate 106, also in corresponding positions. The bottoms of both inverted L-shaped limiting plates 105 are fixedly connected to the upper surface of the inverted shell 104. The complementary plate 112 on the inner side of the extension plate 106 can fill the gap between the two extension plates 106, adapting to the support requirements of engines of different widths. The bottoms of the inverted L-shaped limiting plates 105 slidably connected to the front and rear surfaces of the extension plate 106 are fixed to the inverted shell 104, restricting the displacement direction of the extension plate 106 and preventing its lateral displacement. Simultaneously, the sliding fit accommodates the adjustment stroke of the extension plate 106.
[0027] Furthermore, a support assembly 2 is provided above the extension plate 106. The support assembly 2 includes a main support column 201, a reinforcing plate 202 fixedly connected to the outer surface of the main support column 201, an auxiliary load-bearing plate 203 fixedly connected to the side surface of the main support column 201, a support plate 204 fixedly connected to the lower surface of the auxiliary load-bearing plate 203, and the bottom of the support plate 204 fixedly connected to the upper surface of the extension plate 106. The bottom of the main support column 201 is fixedly connected to the upper surface of the extension plate 106. In the support assembly 2, the bottom of the main support column 201 is fixed to the extension plate 106, and the longitudinal stability is enhanced by the reinforcing plate 202 on the outer side. The auxiliary load-bearing plate 203 is connected to the extension plate 106 through the support plate 204, forming a multi-point load-bearing structure to distribute the weight of the engine. The main support column 201 and the auxiliary load-bearing plate 203 work together to improve the rigidity of the tooling's support for the engine.
[0028] Furthermore, an auxiliary reinforcing rod 205 is fixedly connected between the auxiliary load-bearing plate 203 and the extension plate 106, and a rubber pad 206 is fixedly connected to the upper surface of the auxiliary load-bearing plate 203. The upper surface of the rubber pad 206 is provided with anti-slip grooves. The auxiliary reinforcing rod 205 between the auxiliary load-bearing plate 203 and the extension plate 106 further strengthens the connection strength and resists bending moment under load; the rubber pad 206 and anti-slip grooves on the upper surface of the auxiliary load-bearing plate 203 can buffer the impact force when the engine is placed, increase the coefficient of friction, prevent the engine from sliding, and at the same time avoid direct contact between the support surface and the engine, which could cause scratches.
[0029] The complete working process is as follows: First, based on the lateral dimensions of the engine to be supported, preliminary adjustment is made through the movable connection of the strip mounting plate 102 along the strip base plate 101: the rollers 111 at both ends of the connecting rod 110 inside the mounting block 109 roll in contact with the upper surface of the strip base plate 101, converting sliding friction into rolling friction, reducing adjustment resistance, and allowing the strip mounting plate 102 to move smoothly to the target position. Then, fasteners are inserted through the mounting holes 103 on the strip mounting plate 102 and the strip base plate 101 that correspond one-to-one to complete the rigid locking. Subsequently, the electric telescopic rod 108 in the adjustment assembly 1 is activated. It is fixed to the side of the central partition 107 on the inner wall of the inverted shell 104. The output end drives the extension plate 106 to move horizontally through the mounting block 109 and the connecting block 113, realizing fine adjustment of the support position. The front and rear surfaces of the extension plate 106 slide in cooperation with the inverted L-shaped limiting plate 105. The bottom of the limiting plate is fixed to the inverted shell 104, ensuring that the extension plate 106 moves in the preset direction and avoids lateral displacement. At the same time, the complementary plates 112 on the inner sides of the two extension plates 106 move with the extension plate 106, automatically filling the gap and adapting to the engine width requirements. When the extension plate 106 is in place, the four auxiliary support rods 114 between the connecting block 113 and the extension plate 106 form a triangular stable structure, which enhances the connection strength and prevents the extension plate 106 from deforming under force. At this point, the support assembly 2 above the extension plate 106 enters its working state: the main support column 201 is fixed to the extension plate 106 at the bottom, and the outer reinforcing plate 202 enhances longitudinal stability; the auxiliary load-bearing plate 203 is connected to the extension plate 106 via the support plate 204, and together with the auxiliary reinforcing rod 205 between them, it resists the load-bearing bending moment, forming a multi-support point to distribute the load. Finally, the engine is placed on the auxiliary load-bearing plate 203, and the rubber pad 206 and anti-slip grooves on its surface absorb the impact force through elastic buffering, while increasing the coefficient of friction to prevent the engine from sliding and avoiding direct contact between the support surface and the engine to prevent scratches, thus completing the entire support process.
