Description

Technical Field

[0001] This utility model relates to the technical field of cover plate fixing equipment, specifically a clamp for fixing cover plates. Background Technology

[0002] The car engine is the power source for a vehicle; it's the heart of the car, determining its power, economy, stability, and environmental performance. Based on the power source, car engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid engines. Common gasoline and diesel engines are reciprocating piston internal combustion engines, converting the chemical energy of fuel into the mechanical energy of piston movement to output power. Gasoline engines have high speeds, low mass, low noise, easy starting, and low manufacturing costs; diesel engines have high compression ratios, high thermal efficiency, and better fuel economy and emissions performance than gasoline engines. The engine cover is an essential component of the car engine; typically, factories process engine cover plates on CNC machining centers during production.

[0003] However, in the existing technology, if the cover plate of a car engine moves spontaneously during CNC machining, it is easy to scrap the cover plate.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a clamp for fixing the cover plate. Utility Model Content

[0005] The purpose of this invention is to provide a clamp for fixing a cover plate, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clamping solution for fixing a cover plate includes a fixing plate, a connecting component on the fixing plate, a positioning box fixed on the top surface of the fixing plate, a cavity inside the positioning box, a vent hole I communicating with the cavity on the top surface of the positioning box, a second vent hole II communicating with the cavity on one side of the positioning box, a positioning component I on the top surface of the fixing plate, and a positioning post on the top surface of the positioning box.

[0008] As a preferred technical solution, the connecting assembly includes two bolts, and the top surface of the fixing plate has two threaded holes symmetrically formed, with the two bolts threadedly connected to the two threaded holes respectively.

[0009] As a preferred technical solution, the number of positioning posts is two, the two positioning posts are symmetrically arranged, and both positioning posts are integrally formed with the positioning box.

[0010] As a preferred technical solution, the positioning component includes a cylinder, which is horizontally mounted on the top surface of the fixed plate, and a positioning block is slidably connected to the top surface of the fixed plate on the piston rod of the cylinder.

[0011] As a preferred technical solution, the top surface of the fixing plate is provided with a placement groove, and the positioning box is disposed in the placement groove.

[0012] As a preferred technical solution, the top surface of the positioning box is provided with a strip-shaped hole one that communicates with the ventilation hole one, the top surface of the positioning box is symmetrically provided with a strip-shaped hole two that communicates with the strip-shaped hole one, and the top surface of the positioning box is provided with a strip-shaped hole three that communicates with the ventilation hole one.

[0019] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0020] like Figure 1 As shown, this utility model provides a clamping solution for fixing a cover plate: it includes a fixing plate 1, which is rectangular in shape, and two sets of connecting components are symmetrically arranged on the fixing plate 1. The connecting components fix the fixing plate 1 in a pre-set position.

[0021] In this embodiment, taking one set of connecting components as an example, the connecting components include two bolts, two threaded holes 6 are symmetrically opened on the top surface of the fixing plate 1, and two threaded holes 2 corresponding to the two threaded holes 6 are opened at the installation position of the CNC machining center. Then, the two bolts are threaded into the two threaded holes 6 respectively, and the extension ends of the two bolts are threaded into the two threaded holes 2 respectively, so as to fix the fixing plate 1 and the CNC machining center.

[0022] In this embodiment, a placement groove 10 is provided on the top surface of the fixing plate 1, and a positioning box 2 is fixed in the placement groove 10. The placement groove 10 has the function of limiting the movement of the positioning box 2, and also makes it convenient for the staff to fix the positioning box 2 to the fixing plate 1.

[0023] The positioning box 2 has a cavity inside. A vent 3 connected to the cavity is opened on the top surface of the positioning box 2, and a vent 4 connected to the cavity is opened on one side of the positioning box 2. The operator places the cover plate to be processed on the surface of the positioning box 2, and then connects the pre-prepared vacuum generator to the vent 4. Air is drawn out through the vent 4, and the gas between the cover plate and the positioning box 2 enters the cavity through the vent 3 and is discharged to the outside through the vent 4, thus fixing the cover plate to the positioning box 2. This reduces the possibility of the cover plate moving spontaneously during processing. Moreover, the whole process is automated and does not require the participation of operators, saving time and effort.

[0024] In this embodiment, two positioning posts 5 are provided on the top surface of the positioning box 2. The two positioning posts 5 are symmetrically arranged and are integrally formed with the positioning box 2. The two holes of the cover plate can be placed on the two positioning posts 5. The two positioning posts 5 have a limiting effect on the cover plate.

[0025] In this embodiment, a positioning component 1 is provided on the top surface of the fixed plate 1. The positioning component 1 and the two positioning posts 5 complement each other. The positioning component 1 includes a cylinder 8, which is horizontally installed on the top surface of the fixed plate 1. A positioning block 9 is slidably connected to the top surface of the fixed plate 1 on the piston rod of the cylinder 8. When the cylinder 8 is started, the cylinder 8 drives the positioning block 9 to move linearly. The positioning block 9 is engaged with the cover plate and has a limiting function on the cover plate.

[0026] In this embodiment, a strip-shaped hole 11 communicating with a vent hole 3 is provided on the top surface of the positioning box 2, a strip-shaped hole 12 communicating with the strip-shaped hole 11 is symmetrically provided on the top surface of the positioning box 2, and a strip-shaped hole 3 communicating with a vent hole 3 is provided on the top surface of the positioning box 2. The strip-shaped holes 11, 12 and 3 facilitate the vent hole 3 to draw in air between the cover plate and the positioning box 2.

[0027] In this embodiment, a fixing groove 14 is provided on the top surface of the fixing box, and a sealing ring 15 is installed in the fixing groove 14, which serves as a seal.
