[0002] The cylinder head, also known as the cylinder cover, is installed on the top of the engine cylinder block. Its main function is to seal the cylinder from the top. It, the cylinder block, and the piston together form the combustion chamber. Figure 4 As shown, the cylinder head has a complex shape, with a slightly arched cuboid at the bottom, two side surfaces 41 formed on both sides of the cuboid, a bottom surface 43 formed on the bottom of the cuboid, and a hollow cylinder with a plurality of annular grooves formed on the outer peripheral surface on the upper part, and a top surface 42 formed on the hollow cylinder. For subsequent processing, it needs to be fixed with a clamp, and secondly, the non-overlapping surface of the cuboid and the hollow cylinder forms a processing surface 44, and the processing surface 44 needs to be milled to form a concave long groove.

[0003] The existing processing positioning mostly uses traditional clamps, pressure plates, equal height blocks and other clamps to fix the top and side surfaces of the cylinder head. Due to the complex shape of the cylinder head, the fixture installation process is time-consuming and labor-intensive, and a set of clamps can only clamp one cylinder head. After processing one cylinder head, the clamp needs to be removed and the other cylinder head needs to be re-clamped. The existing cylinder head clamp can process a small number of cylinder heads per unit time, and the cylinder head processing efficiency is low. Utility Model Content

[0019] Embodiment 1

[0020] like Figures 1 to 3 As shown, an embodiment of the utility model includes: a mounting assembly 1, which includes at least two mounting discs 12, and the top surfaces of the mounting discs 12 are each formed with a mounting surface 14, and the mounting surfaces 14 can overlap together; a side clamp assembly 2 arranged on the mounting surface 14, and the side clamp assembly 2 is provided with parallel double surfaces, the spacing between the parallel double surfaces is adjustable, and the parallel double surfaces are perpendicular to the mounting surface 14; a pressing assembly 3 arranged on the mounting surface 14, and the pressing assembly 3 includes a multi-pressure head 32 arranged between the mounting discs 12, and the multi-pressure head 32 has at least two overlapping multi-pressure surfaces 35 formed on one side close to the mounting surface 14, and the multi-pressure surface 35 is parallel to the mounting surface 14.

[0021] Specifically, multiple mounting discs 12 are respectively formed with mounting surfaces 14, and the mounting surfaces 14 overlap together, so that the top surface height of the mounting disc 12 is consistent, which is convenient for the subsequent placement of the cylinder head 4; the parallel double surfaces can be fixed on one side and approach the fixed surface on the other side. At this time, the fixed side passes through the central axis of the mounting disc 12, or the two sides can be moved towards each other by the same distance. At this time, the middle surface of the parallel double surfaces passes through the central axis of the mounting disc 12, so that when the cylinder head 4 is placed on the mounting disc 12, after the two sides of the cylinder head 4 are clamped by the parallel double surfaces, its central axis always coincides with the central axis of the mounting disc 12; the multi-pressure head 32 is formed with two multi-pressure surfaces 35. This embodiment preferably has double pressure surfaces, that is, the multi-pressure head 32 has two multi-pressure surfaces 35, and the axis of the multi-pressure head 32 can form a plane perpendicular to the mounting surface 14. Multiple multi-pressure surfaces 35 can also overlap together, so that the top surfaces of multiple cylinder heads 4 installed on multiple mounting discs 12 can be maintained in the same horizontal plane.

[0022] Furthermore, the pressing assembly 3 also includes: a single pressing head 31, which can only form a single pressing surface 34 on the side of the single pressing head 31 close to the mounting surface 14, the single pressing surface 34 and the multiple pressing surfaces 35 are at the same distance from the mounting surface 14, and there is only one single pressing surface 34 and one multiple pressing surface 35 above the single mounting surface 14; and a pressing power member 33, which can simultaneously adjust the distance between the single pressing surface 34, the multiple pressing surfaces 35 and the mounting surface 14.

[0023] Specifically, the top surface of the cylinder head 4 needs to be processed with holes, and the positions of the processed holes need to be exposed. Therefore, the clamping points of the top surface of the cylinder head 4 are two points symmetrical with the center of the top surface. In this embodiment, the multi-pressing head 32 clamps one side of the top surface of the cylinder head 4, and the single press head 31 can clamp the other side of the top surface of the cylinder head 4, so that the top surface of the cylinder head 4 is evenly stressed, ensuring the levelness of its processed surface 42. The downward pressing power member 33 is preferably a cylinder, which pushes the single press head 31 and the multi-pressing head 32 to simultaneously press the cylinder head 4, limiting the up and down movement of the cylinder head 4.

[0024] Furthermore, at least two grooves are formed on the top surface of the mounting disc 12, and the grooves are evenly distributed on the circumference of the mounting disc 12 and divide the mounting disc 12 into two mounting areas. The mounting assembly 1 also includes: a base plate 11 arranged on the bottom surface of the mounting disc 12, and a plurality of mounting discs 12 are arranged on the top surface of the base plate 11; a positioning pin 15 is arranged on the top surface of the mounting disc 12, and the positioning pin 15 is arranged at the center of the mounting disc 12, and the axis of the positioning pin 15 is perpendicular to the mounting surface 14; and an airtight hole 13 that penetrates the mounting disc 12 along the axial direction of the mounting disc 12, and the airtight holes 13 are evenly distributed in the mounting area.

[0025] Specifically, in the present embodiment, four grooves are preferably used for placing bolts to connect the mounting disc 12 to the base plate 11, so that when the bottom surface of the cylinder head 4 contacts the four mounting areas formed by the mounting disc 12, the contact area between the mounting surface 14 and the bottom surface of the cylinder head 4 can be reduced, and a good supporting and positioning function can be provided. The reduced contact area can reduce the possibility of iron filings between the bottom surface of the cylinder head 4 and the mounting surface 14; the airtightness detection equipment blows air through the airtight hole 13 to detect whether there is a gap between the bottom surface of the cylinder head 4 and the mounting surface 14. The setting of the four mounting areas can improve the sealing performance between the bottom surface of the cylinder head 4 and the mounting surface 14.

[0026] Secondly, the positioning pin 15 installed at the center of the installation disk 12 cooperates with the installation surface 14 to ensure the installation position accuracy of the cylinder head 4, which is convenient for subsequent processing thereof.

[0027] Furthermore, the mounting discs 12 are arranged on the base plate 11 in three rows and four columns, the single pressure head 31 is arranged between the mounting disc 12 and the edge of the base plate 11, and the multiple pressure heads 32 are arranged between the mounting discs 12. The center points of each row of single pressure heads 31, multiple pressure heads 32 and mounting discs 12 can form a row line, and the center points of each column of single pressure heads 31, multiple pressure heads 32 and mounting discs 12 can form a column line, and the row line is perpendicular to the column line.

[0028] Specifically, in the present embodiment, the preferred way of installing the disc 12 is to clamp the cylinder head 4 with twelve mounting discs 12 at the same time. At this time, six single pressure heads 31 are required on the edge of the base plate 11 to clamp one side of the top surface of the cylinder head 4 at the edge, and nine multiple pressure heads 32 are required in the middle area of ​​the base plate 11. One multiple pressure head 32 can clamp the top surfaces of the cylinder heads 4 on both sides at the same time, thereby improving the utilization rate of the clamp and reducing the usage space.

[0029] Furthermore, the side clamp assembly 2 includes: a first clamping member 21 and a second clamping member 23 arranged on one side of the mounting disc 12, and the first clamping member 21 and the second clamping member 23 have a first clamping surface 22 and a second clamping surface 24 formed on opposite sides thereof, respectively, and the first clamping surface 22 and the second clamping surface 24 together constitute a parallel double surface; and a side clamping power member 25 capable of adjusting the distance between the first clamping surface 22 and the second clamping surface 24.

[0030] Specifically, the side clamping power member 25 is preferably a single-rod cylinder. At this time, the second clamping surface 24 is fixedly installed on one side of the disc 12. The second clamping surface 24 is squeezed on one side of the cylinder head 4 under the drive of the single-rod cylinder, so that the middle surface of the first clamping surface 22 and the second clamping surface 24 passes through the axis of the positioning pin 15, thereby ensuring the installation accuracy of the cylinder head 4, and then ensuring its position accuracy when the cylinder head 4 is subsequently processed.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
