Description

Technical Field

[0001] This utility model relates to the field of cylinder head cover manufacturing technology, and in particular to a positioning device for cylinder head cover manufacturing. Background Technology

[0002] The cylinder head cover is a cover that covers the engine block. It prevents external impurities from entering the engine and also serves as a seal.

[0003] Patent application CN201921306962.4 discloses a positioning device for cylinder head cover production. This device utilizes four vertically arranged hydraulic cylinders welded to the four corners of the top of a base, a horizontally arranged processing table above the base, and four vertically arranged fixing sleeves welded to the four corners of the bottom of the processing table. This addresses the problem that while existing positioning devices can position cylinder head covers, their positioning components are often integrated with the device itself. After prolonged use and wear, it is difficult for users to quickly and easily disassemble and reassemble the positioning components. Furthermore, the fixing process in this solution is cumbersome and slow, thus reducing the production efficiency of cylinder head covers. Therefore, this patent proposes a positioning device for cylinder head cover production to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a positioning device for cylinder head cover production that can solve the above-mentioned problem.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for cylinder head cover production, comprising a stamping machine, wherein a stamping cylinder is installed inside the upper end of the stamping machine, a supporting mold is fixedly connected inside the internal platform of the stamping machine, a stamping head is fixedly connected to the output end of the stamping cylinder, and a stamping template is installed on the stamping head;

[0006] The stamping machine is equipped with an electrical control box and control buttons;

[0007] The support mold is equipped with a positioning mechanism for positioning the cylinder head cover.

[0008] Preferably, the positioning mechanism includes four positioning corner brackets, which are slidably connected to the surface of the supporting mold.

[0009] The support mold has four sliding grooves arranged in an "X" shape array.

[0010] Each of the two diagonally opposite grooves is rotatably connected to a threaded rod, and the diagonal brackets are threadedly connected to the corresponding threaded rods.

[0011] The two threaded rods are rotated by an external drive mechanism.

[0012] Preferably, the threaded rod has opposite threads at both ends starting from the center position, and the two diagonal corner brackets are threadedly connected to the square thread of the threaded rod.

[0013] Preferably, each of the corner brackets has a shovel plate fixedly connected to its inner wall. The shovel plate is right-angled and its upper surface is inclined.

[0014] Preferably, the stamping press has a sliding rod internally connected to it, and a push plate is fixedly connected to the sliding rod;

[0015] A spring is movably connected to the slide rod, and the two ends of the spring are fixedly connected to the push plate and the inner wall of the press, respectively.

[0016] Preferably, buffer pads are fixedly connected to both the surface of the push plate and the inner wall of the corner bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) The positioning device for cylinder head cover production, after the cylinder head cover is placed on the support mold, the drive mechanism is started to control the threaded rod to rotate. As the threaded rod rotates, the corner brackets move relative to each other, and thus gradually contact the four corners of the cylinder head cover and fix them. Therefore, it achieves the effect of positioning and fixing the cylinder head cover. By fixing at the four corners, not only is the contact area with the cylinder head cover reduced, but the stability during the fixing process is also improved. At the same time, the positioning speed of the cylinder head cover is faster, reducing unnecessary cumbersome steps, thus improving processing efficiency, while ensuring safety and accuracy during the punching process.

[0019] (2) The positioning device for cylinder head cover production has a shovel plate. When the corner bracket is fixing the cylinder head cover, the shovel plate is inserted into the bottom of the cylinder head cover, causing the cylinder head cover to move slightly upward. This leaves a certain gap between the cylinder head cover and the support mold, thereby ensuring that the cylinder head cover can be punched normally. This avoids the cylinder head cover and the support mold from being completely fitted together, which would cause the support mold to be damaged by the high pressure during the punching process.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a positioning device for cylinder head cover production, including a stamping machine 1, a stamping cylinder 15 installed inside the upper end of the stamping machine 1, a support mold 5 fixedly connected inside the internal platform of the stamping machine 1, a stamping head 3 fixedly connected to the output end of the stamping cylinder 15, and a stamping template 6 installed on the stamping head 3.

[0026] The stamping machine 1 is equipped with a power distribution box 2 and control buttons 4;

[0027] Among them, the power distribution box 2 is used to manage the circuit of the stamping machine 1, and the control button 4 is used to control the stamping machine 1.

[0028] The support mold 5 is equipped with a positioning mechanism for positioning the cylinder head cover.

[0029] When it is necessary to punch holes in the cylinder head cover, it can be placed on the support mold 5. At this time, it is positioned and fixed by the positioning mechanism, thus ensuring that it is perpendicular to the stamping template 6, thereby ensuring the accuracy of the punching position and avoiding displacement of the cylinder head cover during the punching process. At this time, the stamping cylinder 15 is activated, and its output end drives the stamping head 3 and the stamping template 6 to slide down and contact the cylinder head cover, thus completing the punching operation under pressure.

[0030] Furthermore, the positioning mechanism includes four positioning brackets 9, which are slidably connected to the surface of the supporting mold 5.

[0031] The support mold 5 has four sliding grooves 7, which are arranged in an "X" shape array.

[0032] Each of the two diagonally opposite sliding grooves 7 is rotatably connected to a threaded rod 8, and the diagonally opposite corner brackets 9 are threadedly connected to the corresponding threaded rods 8.

[0033] Among them, the threaded rod 8 has opposite threads at both ends starting from the center position, and the two diagonal corner brackets 9 are respectively threaded to the square thread of the threaded rod 8;

[0034] The two threaded rods 8 are rotated by an external drive mechanism;

[0035] After the cylinder head cover is placed on the support mold 5, the drive mechanism is started to control the threaded rod 8 to rotate. As the threaded rod 8 rotates, the corner brackets 9 move relative to it, and thus gradually contact the four corners of the cylinder head cover and fix it. This achieves the effect of positioning and fixing the cylinder head cover. By fixing it at the four corners, not only is the contact area with the cylinder head cover reduced, but the stability during the fixing process is also improved, thus ensuring safety and accuracy during the punching process.

[0036] Furthermore, each of the corner brackets 9 has a shovel plate 10 fixedly connected to its inner wall. The shovel plate 10 is right-angled and its upper surface is inclined.

[0037] With the shovel plate 10 in place, when the corner bracket 9 is fixing the cylinder head cover, the shovel plate 10 is inserted into the bottom of the cylinder head cover, causing the cylinder head cover to move slightly upward. This leaves a certain gap between the cylinder head cover and the support mold 5, thereby ensuring that the cylinder head cover can be punched normally, and avoiding the phenomenon that the cylinder head cover and the support mold 5 are completely fitted together, causing the support mold 5 to be damaged by the high pressure during the punching process.

[0038] Furthermore, the internal sliding connection of the stamping machine 1 is a slide rod 12, and a push plate 11 is fixedly connected to the slide rod 12;

[0039] A spring 13 is movably sleeved on the slide bar 12, and the two ends of the spring 13 are respectively fixedly connected to the push plate 11 and the inner wall of the press 1.

[0040] When the cylinder head cover enters the working position, the push plate 11 is slid under force by the push plate 11, which compresses the spring 13. After the punching is completed, the spring 13 releases its elasticity as the positioning mechanism is released, so that the slide rod 11 and the push plate 11 are reset. Therefore, it can push the cylinder head cover after the stamping is completed, so that it can be taken out from the inside of the stamping machine 1 more easily.

[0041] A buffer pad 14 is fixedly connected to both the surface of the push plate 11 and the inner wall of the corner bracket 9;

[0042] The buffer pad 14 prevents the pusher plate 11 from causing wear to the cylinder head cover when it comes into contact with it, thus ensuring that its appearance is not damaged.

[0043] Working principle: After the cylinder head cover is placed on the support mold 5, the drive mechanism is started to control the threaded rod 8 to rotate. As the threaded rod 8 rotates, the corner brackets 9 move relative to it, and thus gradually contact the four corners of the cylinder head cover and fix it. This achieves the effect of positioning and fixing the cylinder head cover. By fixing it at the four corners, not only is the contact area with the cylinder head cover reduced, but the stability during the fixing process is also improved, thus ensuring safety and accuracy during the punching process.

[0044] With the shovel plate 10 in place, when the corner bracket 9 is fixing the cylinder head cover, the shovel plate 10 is inserted into the bottom of the cylinder head cover, causing the cylinder head cover to move slightly upward. This leaves a certain gap between the cylinder head cover and the support mold 5, thereby ensuring that the cylinder head cover can be punched normally, and avoiding the phenomenon that the cylinder head cover and the support mold 5 are completely fitted together, causing the support mold 5 to be damaged by the high pressure during the punching process.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
