Description

Technical Field

[0001] This utility model belongs to the field of automotive industry technology, specifically relating to an adjustable height tilting table for engine cylinder heads. Background Technology

[0002] According to the technical solution of an engine cylinder head tilting platform disclosed in CN215316795U, it mainly includes a frame, a support frame, a rectangular frame, columns, a mounting frame, a levering part, an annular boss, a mounting base, and other structures. The frame includes a support frame one and a support frame two fixed to the upper middle part of the support frame one. The support frame one includes two rectangular frames one arranged vertically and horizontally. The four corners of the two rectangular frames one are connected by vertically arranged columns. The four corners of the lower rectangular frame one are provided with feet that are connected to the ground. The support frame two includes two vertically arranged rectangular frames two. The two rectangular frames two are respectively fixed to the upper middle part of the two ends of the upper rectangular frame one and extend along the width direction of the rectangular frame one. The lower inner side of the two rectangular frames two has two straight rods fixed along the length direction of the rectangular frame one.

[0003] However, the following problems still exist in the practical application of this solution: Based on the connection method, functional requirements and structural rationality described in the claims and specification of this technical solution, it can be seen that the frame and its included structure are an integral structure. This results in: the distance between the mounting bracket and the frame is fixed and cannot be adjusted, making it difficult to adapt to engine cylinder heads of different sizes, which may cause the mounting bracket to be obstructed when flipping, and it cannot be matched with the work posture of operators of different heights, which may slow down the operation and affect work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable height tilting platform for engine cylinder heads. This platform uses a servo electric cylinder to drive an anti-tipping lifting structure to achieve vertical displacement, with synchronized movement of the support rod. This not only allows for flexible adjustment of the vertical height of the mounting bracket but also significantly enhances the lateral anti-tipping capability of the gantry frame. It can adapt to engine cylinder heads of different sizes, effectively ensuring operational safety; furthermore, it can match the horizontal plane of the workstation according to the height differences of the operators, thereby improving the ease of operation and work efficiency of the engine cylinder head.

[0005] The specific technical solution adopted by this utility model is as follows: An adjustable height tilting platform for engine cylinder heads includes a frame, with anti-tipping lifting structures symmetrically arranged at both ends of the top of the frame. The anti-tipping lifting structures include: The U-shaped frame has a portal frame fixedly connected to one side of its bottom; Two support rods are symmetrically arranged on the side wall of the portal frame, and the support rods are provided with guide grooves along their length; The sliding shaft has two ends that are slidably fitted into the two guide grooves, and the two sliding shafts are fixedly connected by a horizontal plate to form a synchronous linkage structure. The support rod, cross plate and sliding shaft constitute an A-type stable structure; A sliding groove is formed through the top of the frame, and one end of the support rod slides horizontally with the corresponding sliding groove.

[0006] The top of the gantry frame has a recessed parts box.

[0007] Limiting rods are fixedly installed at the top of the frame corresponding to the two vertical plates of the U-shaped frame, and the vertical plates of the U-shaped frame are slidably sleeved on the outer wall of the limiting rods.

[0008] Servo electric cylinders are symmetrically installed at both ends of the frame, and the output end of the servo electric cylinder is connected to the bottom of the gantry frame for transmission.

[0009] A PLC controller and a two-way switch are arranged sequentially from bottom to top on one side of the frame. The two servo electric cylinders are synchronously connected to the PLC controller and the two-way switch via cables.

[0010] A mounting frame is provided on the top of the frame, and the two ends of the mounting frame are respectively rotatably connected to the two portal frames; The sliding groove is formed at both ends of the short side plate of the frame, and its length is less than the length of the short side plate, so as to limit the movement of the support rod in the sliding groove.

[0011] The technical advantages achieved by this utility model are as follows: by using a servo electric cylinder to drive the anti-tipping lifting structure to achieve vertical displacement, and synchronously linking the support rod to move in coordination, not only is the vertical height of the mounting frame flexibly adjusted, but the lateral anti-tipping capability of the gantry frame is also significantly enhanced. It can adapt to engine cylinder heads of different sizes, effectively ensuring operational safety; and it can also match the horizontal plane of the work station according to the height difference of the operator, thereby improving the operational convenience and work efficiency of the engine cylinder head.

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0015] This utility model provides an adjustable height tilting platform for engine cylinder heads, based on the structure of patent CN215316795U, mainly improving the connection relationship between the frame and the mounting bracket; the structure of all components in the original patent except for the improved components proposed in this utility model remains unchanged, and the specific structure can be found in the embodiments of the original patent.

[0016] like Figures 1-2 As shown, an adjustable height tilting platform for engine cylinder heads includes a frame 1. Anti-tipping lifting structures are symmetrically arranged at both ends of the top of the frame 1. The anti-tipping lifting structures include: a U-shaped frame 101, with a gantry frame 102 fixedly connected to one side of its bottom; limit rods 109 are fixedly arranged at the top of the frame 1 corresponding to the two vertical plates of the U-shaped frame 101, and the vertical plates of the U-shaped frame 101 are slidably fitted onto the outer wall of the limit rods 109; servo cylinders 113 are symmetrically installed at both ends of the frame 1, and the output ends of the servo cylinders 113 are connected to the bottom of the gantry frame 102 via a transmission connection; a PLC controller 110 and a two-way switch 111 are sequentially arranged from bottom to top on one side of the frame 1, and the two servo cylinders 113 are synchronously connected to the PLC controller 110 and the two-way switch 111 via cables; a mounting bracket 112 is provided above the frame 1, with both ends of the mounting bracket 112 rotatably connected to the two gantry frames 102 respectively.

[0017] According to the above structure, during operation, the equipment uses frame 1 as the main frame, and the servo electric cylinder 113 is powered to provide lifting power. The operator sends up or down commands through the two-way switch 111, and the PLC controller 110 receives the commands and drives the servo electric cylinder 113 to execute them. Furthermore, when the mounting bracket 112 needs to be raised, the two-way switch 111 is pressed to raise the button, and the PLC controller 110 sends a positive operation signal to the servo cylinder 113. The gantry frame 102 drives the U-shaped frame 101 to rise, and vice versa, thereby changing the distance between the mounting bracket 112 and the frame 1, so as to adapt to different sizes of engine cylinder heads. The end of the limit rod 109 is set to have a diameter larger than its body to limit the maximum lifting stroke of the U-shaped frame 101.

[0018] Reference Appendix Figures 1-2 The top of the portal frame 102 has a recessed parts box 103. Two support rods 105 are symmetrically arranged on the side wall of the portal frame 102. The support rods 105 have guide grooves 104 along their length. The sliding shafts 107 have their two ends slidably engaged in the two guide grooves 104 respectively. The two sliding shafts 107 are fixedly connected by a horizontal plate 108 to form a synchronous linkage structure. The support rods 105, the horizontal plate 108 and the sliding shafts 107 constitute an A-type stable structure. A sliding groove 106 is opened through the top of the frame 1. One end of the support rod 105 is horizontally slidably engaged with the corresponding sliding groove 106. The sliding grooves 106 are opened at both ends of the short side plate of the frame 1, and their length is less than the length of the short side plate to limit the movement of the support rods 105 in the sliding grooves 106.

[0019] According to the above structure, the parts box 103 can be used to place disassembled cylinder head parts. The top two ends of the frame 1 are symmetrically provided with anti-tipping lifting structures, which are based on the U-shaped frame 101 and the gantry frame 102. The side wall of the gantry frame 102 is rotatably connected to two support rods 105 through pins. The support rods 105 have guide grooves 104 along the length direction. The two ends of the sliding shaft 107 are respectively embedded in the guide grooves 104 of the support rods 105 on the left and right sides, and are fixed by the horizontal plate 108 to form a synchronous linkage structure. Furthermore, the end of the support rod 105 away from the portal frame 102 is horizontally slidably engaged with the sliding groove 106 at the top of the frame 1, forming a floating fulcrum that can be displaced in the horizontal direction. When the portal frame 102 drives the U-shaped frame 101 and the mounting frame 112 to move up and down, the sliding shaft 107 slides in the guide groove 104, so that the support rod 105 maintains the A-shaped stable structure while moving up and down with the portal frame 102. The floating engagement of the support rod 105 ensures that the portal frame 102 is always laterally constrained, improving the anti-overturning ability of the portal frame 102, U-shaped frame 101 and mounting frame 112. The length of the sliding groove 106 is less than the total length of the short side plate of the frame 1, ensuring that when the portal frame 102 is raised to the limit position, the support rod 105 is still in an inclined state, maintaining the A-shaped structure, and preventing the support rod 105 from being vertical, causing the horizontal plate 108 to slide down to the bottom and get stuck due to gravity.

[0020] The working principle of this utility model is as follows: A PLC controller 110 and a two-way switch 111 are integrated on one side of the frame 1, and the two are electrically connected to the servo cylinder 113 via cables. After the operator selects the operating mode through the two-way switch 111, the PLC controller 110 receives the command and drives the servo cylinder 113 to move. For example, when it is necessary to raise the mounting frame 112, the PLC controller 110 sends a positive operation signal to the servo cylinder 113, and the gantry frame 102 drives the U-shaped frame 101 to rise; conversely, it lowers. Furthermore, the limiting rod 109 is embedded in the vertical plate of the U-shaped frame 101 to limit its maximum stroke and prevent safety hazards caused by excessive displacement. During operation, the servo electric cylinder 113 serves as a power source, and its output end is connected to the bottom of the gantry frame 102. When the servo electric cylinder 113 is activated, the gantry frame 102 drives the U-shaped frame 101 and the entire anti-tipping lifting structure to move up and down. The parts box 103 can be used to place disassembled cylinder head parts. Furthermore, the anti-tipping lifting structure consists of a U-shaped frame 101 as the basic load-bearing unit. A portal frame 102 is fixedly connected to the bottom of the U-shaped frame 101. Two support rods 105 are rotatably connected to the side walls of the portal frame 102 via pins. Guide grooves 104 are formed along the length of each support rod 105. The two ends of a sliding shaft 107 are respectively embedded in the guide grooves 104 of the left and right support rods 105, and are fixed by a horizontal plate 108 to form a synchronous linkage structure. The end of the support rod 105 furthest from the portal frame 102 slides horizontally with a sliding groove 106 at the top of the frame 1, forming a floating fulcrum that can move horizontally. Furthermore, the support rod 105 moves synchronously under the constraints of the guide groove 104 and the sliding shaft 107: the sliding shaft 107 slides in the guide groove 104, forcing the support rod 105 to move up and down with the gantry frame 102 while maintaining the A-shaped stable structure. The floating cooperation of the support rod 105 ensures that the gantry frame 102 is always laterally constrained, improving the equipment's anti-overturning ability. The length of the sliding groove 106 is less than the total length of the short side plate of the frame 1, ensuring that when the gantry frame 102 is raised to the limit position, the support rod 105 is still in an inclined state, maintaining the A-shaped structure and preventing the support rod 105 from being vertical, causing the horizontal plate 108 to slide down to the bottom and get stuck due to gravity.

[0021] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
