The traditional engine cylinder body support device mostly adopts a fixed structure, is often specially designed and manufactured for a specific model of engine cylinder body, and has poor universality; lacks a multi-point clamping function, is difficult to adapt to the curved surface characteristics of the engine cylinder body, and has poor adjustability. CONTENT OF THE UTILITY MODEL

[0003] In view of the above technical deficiencies, the utility model aims at providing an engine cylinder body support bench which can adjust the clamping position according to the edge shape of the engine cylinder body.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1:

[0038] like Figures 1 to 7 As shown, Embodiment 1 of this utility model provides an engine cylinder block support frame for supporting engine cylinder blocks. Specifically, it includes a base 1 and multiple positioning units 5 disposed on the base 1. The position of the positioning units 5 on the base 1 can be adjusted according to the specific shape of the engine cylinder block, thereby greatly improving the adaptability of the support frame to different engine cylinder blocks.

[0039] First, two parallel longitudinal slide rails 2 are fixedly installed on the upper surface of the base 1. Multiple longitudinal sliders 3 are provided on the longitudinal slide rails 2, which can move along their length. The tops of two corresponding longitudinal sliders 3 on the two longitudinal slide rails 2 are fixedly connected to the same transverse slide rail 4. A second wing bolt 10 is threaded onto one end of the top surface of the longitudinal slider 3 to lock its longitudinal position on the longitudinal slide rail 2. Two slidable positioning units 5 are installed on each transverse slide rail 4. Each positioning unit 5 includes a transverse slider 6, a rotating sleeve 8, and a clamping assembly. The transverse slider 6 forms a sliding fit with the transverse slide rail 4, and its top end is threaded with a first wing bolt 7 to fix its position on the transverse slide rail 4. Through the above structure, the position of the positioning unit 5 can be adjusted according to different engine block shapes and sizes by moving the position of the transverse slide rail 4 on the longitudinal slide rail 2 and the position of the positioning unit 5 on the transverse slide rail 4, thereby facilitating the fixing of the engine block.

[0040] The positioning unit 5 includes a first clamping plate 501 and a second clamping plate 502 arranged in parallel. A guide rod 504 is fixed on the first clamping plate 501 and passes through the second clamping plate 502. The second clamping plate 502 can slide along the guide rod 504. The rotating sleeve 8 is vertically fixed to the surface of the transverse slider 6. A rotatable rotating rod 9 is installed inside through a bearing. The top end of the rotating rod 9 is fixedly connected to the first clamping plate 501, which gives the first clamping plate 501 a 360° rotation adjustment function. The orientation of the first clamping plate 501 can be adjusted according to the shape of the engine block edge, so as to clamp more securely.

[0041] The top of the guide rod 504 extends above the second clamping plate 502 and a pressure block 505 is slidably mounted thereon. The pressure block 505 is L-shaped. A screw 506 parallel to the guide rod 504 is rotatably mounted on the first clamping plate 501, and a threaded hole on the pressure block 505 forms a transmission engagement with the screw 506. The end of the second clamping plate 502 is connected to the extension plate 503 via a hinge. When the screw 506 is rotated, the pressure block 505 can move axially along the guide rod 504. The end of the pressure block 505 abuts against the extension plate 503. When the pressure block 505 presses down on the extension plate 503, the extension plate 503 will rotate at the end of the second clamping plate 502. This allows the extension plate 503 to adapt to the inclined surface on the engine block. The pressure block 505 presses down on the extension plate 503, so that it, in an inclined state, cooperates with the first clamping plate 501 to press against the engine block, improving the fit between the extension plate 503 and the engine block. If the clamping part is a plane, the pressure block 505 can press down on the extension plate 503 until the extension plate 503 rotates to be coplanar with the second clamping plate 502. At that time, the end of the extension plate 503 abuts against the end of the second clamping plate 502, restricting the extension plate 503 from rotating further, thereby forming a continuous support surface with the second clamping plate 502, and thus cooperating with the first clamping plate 501 to clamp the flat part of the engine cylinder block.

[0042] Through the above settings, the longitudinal and transverse multi-level slide rail combination designed in this utility model enables the free adjustment of the positioning unit 5, significantly improving clamping efficiency and adaptability to working conditions; the designed extension plate 503 enhances the adaptability to curved surfaces and clamps more firmly.

[0043] Example 2:

[0044] Based on Embodiment 1, this utility model further includes a spring 507 fitted onto the guide rod 504 between the first clamping plate 501 and the second clamping plate 502. Under the action of the spring 507, a certain gap is maintained between the second clamping plate 502 and the first clamping plate 501, facilitating the insertion of the engine block edge between the first clamping plate 501 and the second clamping plate 502 for subsequent clamping. When the screw 506 is rotated, causing the pressure block 505 to move downwards, the pressure block 505 pushes the extension plate 503 downwards, thereby compressing the spring 507 on the second clamping plate 502. The extension plate 503, in conjunction with the first clamping plate 501, clamps the edge of the engine block.

[0045] Example 3:

[0046] Based on Embodiments 1 and 2, this utility model improves the base 1. In this embodiment, the base 1 includes two parts: a first plate 101 and a second plate 102. The second plate 102 is located below the first plate 101, forming a support base. The first plate 101 and the second plate 102 are hinged together by a hinge seat 103. The second plate 102 is designed with a lifting mechanism, which can lift one side of the first plate 101, allowing the second plate 102 to rotate about the hinge axis center of the hinge seat 103, thereby tilting the engine block.

[0047] The lifting mechanism consists of two sets of symmetrically arranged connecting rods 106. First, two connecting rods 106 are hinged to the second plate 102, forming an inverted V-shape. Two locking blocks 104 are hinged to each of these connecting rods 106. One locking block 104 is mounted on a lead screw 105 with a spoked handle via a bearing, while the other locking block 104 is threadedly driven by the lead screw 105. A connecting rod 106 is also hinged to the upper end of each locking block 104, and the other end of the connecting rod 106 is hinged to the first plate 101.

[0048] Rotating the spoke handle causes the lead screw 105 to rotate, thereby driving the two locking blocks 104 to reduce or increase the distance between them. The distance between the first plate 101 and the second plate 102 is changed through the connecting rod 106, causing the first plate 101 to rotate around the hinge axis, thus realizing the stepless adjustment of the engine cylinder tilt angle.

[0049] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
