Description

Technical Field

[0001] The utility model belongs to the technical field of automobile manufacturing, and particularly relates to a precise positioning and clamping device for processing a cylinder head. Background Art

[0002] The cylinder head is a crucial component of a vehicle engine. Located on top of the engine, it covers the cylinder block and acts as a seal. To improve cylinder head production efficiency and ensure product quality, modern automotive engine production lines commonly employ robotic arms for gripping and handling cylinder heads. These arms are typically equipped with high-precision positioning systems and clamping mechanisms that adapt to the structural characteristics of the cylinder head, enabling stable and accurate gripping and handling. For example, a three-axis truss robotic arm, constructed using a rectangular X, Y, and Z coordinate system, analyzes and processes various input signals through an industrial controller and then issues execution commands to each output element, completing the combined motion of the X, Y, and Z axes.

[0003] In the prior art, the control and movement systems of the manipulator are all arranged at the top of the truss, which is higher than the ground. During the daily maintenance or repair of the manipulator, it is necessary to use climbing tools to climb to a high place to operate, which is not only troublesome and time-consuming, but also there is a risk of the operator falling. Utility Model Content

[0004] The purpose of the utility model is to provide a precise positioning and clamping device for cylinder head processing, which can control the up and down movement of the X-axis arm and the Z-axis arm by rotating the rotating rod, so that the height can be lowered close to the ground, which is convenient for operators to carry out maintenance and repairs, and does not require the use of tools to operate at height, thereby reducing the risk of falling and injury, and the rotating rod can move with the X-axis arm and the Z-axis arm without affecting the normal clamping process.

[0005] The technical solutions adopted by this utility model are as follows:

[0006] The top of described sliding panel also is provided with an interlock plate, and the interlock plate is hinged on the base plate, is fixed with a backing pin on the interlock plate, and an end of sliding panel withstands on the backing pin of interlock plate.

[0007] The outer wall of the rotating rod 1 is fixedly connected to a limiting ring below the horizontal plate 2, and one end of the rotating rod 1 is fixedly connected to a rotating handle below the limiting ring.

[0008] The outer wall of the ferrule is fixedly connected with a sliding block, and rollers are symmetrically rotatably assembled on both sides of the sliding block.

[0009] Sliding grooves for the rollers to engage and slide are provided on the top of the second transverse plate and on both sides of the through groove.

[0010] The two ends of the top of the sliding block are rotatably assembled with a second rotating rod, and the outer wall of the first rotating rod is symmetrically fixedly connected with a protruding column located above the ring.

[0011] The outer wall of the second rotating rod is fixedly connected with a hook for engaging with the convex column, and one end of the X-axis arm is transmission-assembled with a Z-axis arm.

[0012] The technical effect achieved by the utility model is that the X-axis arm and the Z-axis arm can be controlled to move up and down by rotating the rotating rod 1, so that the height can be lowered close to the ground, which is convenient for operators to perform maintenance and repairs. There is no need to use tools to operate at height, which reduces the risk of falling and injury. The rotating rod 1 can move with the X-axis arm and the Z-axis arm without affecting the normal clamping process. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0019] like Figure 1-Figure 3 As shown, a precise positioning and clamping device for cylinder head processing comprises a plurality of axially arranged columns 1, the tops of the columns 1 are fixedly connected to a transverse plate 101, the middle portions of the columns 1 are fixedly connected to a transverse plate 2 102, one side of the transverse plate 101 is fixedly connected to a sliding truss 103, one side of the sliding truss 103 is transmission-assembled with a Y-axis plate 104, one side of the Y-axis plate 104 is fixedly connected to a convex plate 121, the middle portion of the convex plate 121 is vertically slidably connected to a limiting column 120, one end of the limiting column 120 is fixedly connected to a fixed plate 105 below the convex plate 121, the bottom of the fixed plate 105 is transmission-assembled with an X-axis arm 106, and one end of the X-axis arm 106 is transmission-assembled. It is equipped with a Z-axis arm 107, one end of the fixed plate 105 is fixedly connected to the connecting plate 118, the bottom of the horizontal plate 101 is compound-connected with a rotating rod 108, the outer wall of the rotating rod 108 is provided with a threaded groove for threaded connection with the connecting plate 118, the outer wall of the rotating rod 108 and the lower part of the horizontal plate 2 102 are fixedly connected to the limiting ring 119, one end of the rotating rod 108 and the lower part of the limiting ring 119 are fixedly connected with a rotating handle 109, the middle part of the horizontal plate 2 102 is penetrated by a through groove 110 for the rotating rod 108 to pass through, the inside of the through groove 110 is slidably connected with a ring 113, and the ring 113 is rotatably assembled on the outer wall of the rotating rod 108.

[0020] According to the above structure, the bottom of the column 1 is fixed to the ground to support the horizontal plate 101 and the horizontal plate 2 102. When the Y-axis plate 104 slides along the sliding truss 103, it drives the convex plate 121 and the limiting column 120 to slide. The limiting column 120 drives the fixed plate 105 to slide. The fixed plate 105 drives the X-axis arm 106 and the Z-axis arm 107 to slide together. The fixed plate 105 drives the rotating rod 108 to move through the connecting plate 118. When maintenance and repair are required, due to the rotation of the rotating rod 108, The end is connected to the horizontal plate 101 in a sliding manner and is connected in a rotating manner at the same time. By rotating the rotating handle 109, the rotating rod 108 can be driven to rotate. Since the vertical sliding connection between the limiting column 120 and the convex plate 121 can limit the fixed plate 105, when the rotating rod 108 rotates, the connecting plate 118 can drive the fixed plate 105 to move up and down, thereby reducing the height of the X-axis arm 106, the Z-axis arm 107 and its control system. The limiting ring 119 can prevent the rotating rod 108 from shaking left and right when moving.

[0021] Refer to the attached Figure 1-Figure 3The outer wall of the ring 113 is fixedly connected to the sliding block 112, and the two sides of the sliding block 112 are symmetrically assembled with rollers 114. The top of the horizontal plate 102 and the two sides of the through groove 110 are provided with sliding grooves 111 for the rollers 114 to slide in and out. The two ends of the top of the sliding block 112 are rotatably assembled with the rotating rod 2 115. The outer wall of the rotating rod 108 and the upper part of the ring 113 are symmetrically fixedly connected with the protruding column 116. The outer wall of the rotating rod 2 115 is fixedly connected with a hook 117 for buckling with the protruding column 116.

[0022] When the cam 114 is in the state of rotation, the cam 114 can move in the direction of rotation of the cam 116 and the cam 117. When the cam 114 is in the state of rotation, the cam 116 can move in the direction of rotation of the cam 116 and the cam 117. When the cam 114 is in the state of rotation, the cam 116 can move in the direction of rotation of the cam 116 and the cam 117. When the cam 114 is in the state of rotation, the cam 116 can move in the direction of rotation of the cam 116 and the cam 117.

[0023] The working principle of the present invention is as follows: the bottom of the column 1 is fixed to the ground, supporting the horizontal plate 101 and the horizontal plate 2 102. When the Y-axis plate 104 slides along the sliding truss 103, it drives the convex plate 121 and the limiting column 120 to slide. The limiting column 120 drives the fixed plate 105 to slide. The fixed plate 105 drives the X-axis arm 106 and the Z-axis arm 107 to slide together, and the fixed plate 105 drives the rotating rod 108 to move through the connecting plate 118. When maintenance and repair are required, one end of the rotating rod 108 is connected to the horizontal plate 101 in a sliding manner and is rotated at the same time. By rotating the rotating handle 109, the rotating rod 108 can be driven to rotate. Since the limiting column 120 is vertically slidingly connected to the convex plate 121, the fixed plate 105 can be moved. Limiting, when the rotating rod 108 rotates, the connecting plate 118 can drive the fixed plate 105 to move up and down, thereby lowering the height of the X-axis arm 106, the Z-axis arm 107 and its control system, and the limiting ring 119 can prevent the rotating rod 108 from shaking left and right when moving; when the rotating rod 108 moves in the through groove 110, it drives the sliding block 112 to move, and the sliding block 112 drives the roller 114 to move in the sliding groove 111. Rotating the rotating rod 2 115 can make the boss 116 engage with the outer wall of the boss 116, and the movement of the roller 114 in the sliding groove 111 can limit the rotation of the sliding block 112. The sliding block 112 cannot rotate, and the hook 117 cannot rotate either, thereby preventing the rotating rod 108 from rotating during the clamping work.

[0024] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
