Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a pressure plate component of an automobile chassis. Background Art

[0002] Automobile chassis parts generally need to undergo stamping processing during production, and the existing Chinese patent with application number: 202122576277.7 discloses a stamping machine for the production of automobile chassis parts, including a spinning mechanism for punching holes in rubber parts and a support mechanism for installing the spinning mechanism. A clamping mechanism is provided in the support mechanism, and the clamping mechanism includes a push-pull electromagnet and a pressure plate. The spinning mechanism is a sliding and retractable threaded socket structure, and the spinning mechanism includes a middle frame, a sleeve and an inner shaft.

[0003] When the above technology is in use, a push-pull electromagnet is used to drive the pressure plate to move up and down. However, in actual use, the push-pull electromagnet consumes a lot of energy and is prone to heat up, which makes it impossible to use it for a long time at a high frequency, and thus it is not suitable for stamping automobile chassis parts. It is also inconvenient to adjust the clamping thickness during use. Therefore, in order to solve the above technical problems, we proposed an automobile chassis pressure plate component. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an automobile chassis pressure plate component.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The middle part of the pressure plate body is a tool inlet and outlet. Lifting columns are installed on the upper surfaces of both ends of the pressure plate body. The upper end of the lifting column is installed inside the mounting cylinder. One side of the upper end of the mounting cylinder is connected to a pressure regulating component through an air pipe. The lower side of the upper end of the lifting column is connected to a top spring. The lower end of the top spring abuts against the lower end of the inside of the mounting cylinder. A dustproof component is provided on the upper surface of the pressure plate body corresponding to the outside of the lifting column.

[0007] Preferably, the pressure regulating assembly includes a pressure gauge and a pressure relief valve, a bypass pipe is provided on the pipe body of the trachea, and the pressure gauge and the pressure relief valve are both installed on the bypass pipe.

[0008] Preferably, a guide rod is fixed to the upper end of the interior of the installation cylinder, and a matching guide hole is provided inside the lifting column corresponding to the guide rod.

[0009] Preferably, a matching air leakage hole is provided inside the lifting column corresponding to the guide hole, and the upper end of the air leakage hole extends from the outer wall of the upper end of the lifting column.

[0010] Preferably, annular contact pads are installed on the inner and outer sides of the upper end of the lifting column, the contact pads are soaked with lubricating oil, and the upper end of the lifting column contacts the inner wall of the mounting tube and the outer wall of the guide rod through the contact pads.

[0011] Preferably, an oil storage tank is provided at the upper end of the lifting column corresponding to the contact pad, lubricating oil is provided in the oil storage tank, and a suction core is provided at the contact pad corresponding to the oil storage tank.

[0012] Preferably, the dustproof assembly includes a protective tube and a wiping ring, the upper end of the protective tube is slidably sleeved on the outside of the mounting tube through the wiping ring, and the lower end of the protective tube is mounted on the upper surface of the pressure plate body.

[0013] The automobile chassis pressure plate component proposed by the utility model has the following beneficial effects:

[0014] 1: When the pressure plate component proposed in this solution of the utility model is used, the pressure plate body is driven by pneumatic drive instead of traditional push-pull electromagnets. Therefore, compared with the traditional solution, this solution is not only convenient for adjusting the pressure plate body to adapt to the thickness of automobile chassis components, but also in the long-term high-frequency working process, the mounting cylinder and the lifting column are not easily damaged by heat accumulation, and the structure is simple and not prone to failure. At the same time, when the internal pressure of the mounting cylinder is too high, excess gas flows out from the pressure relief valve, thereby preventing the mounting cylinder from being damaged by air pressure, that is, achieving a certain degree of air pressure regulation effect. At the same time, through the setting of the pressure gauge, it is convenient for personnel to monitor the internal pressure of the mounting cylinder, so as to adjust the internal pressure of the mounting cylinder according to the stamping requirements.

[0015] 2: The setting of the guide rod in the present invention improves the stability of the lifting column when it moves up and down to a certain extent, and the setting of the contact pad lubricates the inner wall of the mounting tube and the outer wall of the guide rod when the lifting column moves up and down, so as to keep them smooth for a long time, thereby avoiding the jerkyness between the three and causing excessive wear, and the lubricating oil is the existing lubricating oil for the cylinder. The setting of the oil storage tank and the suction core facilitates the replenishment of the lubricating oil in the contact pad, and the setting of the air bleed hole facilitates the timely release or absorption of the gas in the guide hole when the lifting column moves up and down, thereby avoiding affecting the up and down movement of the lifting column; the setting of the dustproof component prevents external dust from adhering to the outer ring surface of the lifting column, thereby reducing the phenomenon of dust entering the mounting tube and causing abnormal wear between the mounting tube and the lifting column.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1

[0025] Reference Figure 1-6 The automobile chassis pressure plate component includes a mounting cylinder 1 for connecting to an external stamping machine and a pressure plate body 2 arranged below the mounting cylinder 1. The middle part of the pressure plate body 2 is a tool inlet and outlet. Lifting columns 3 are installed on the upper surfaces of both ends of the pressure plate body 2. The upper end of the lifting column 3 is installed inside the mounting cylinder 1. One side of the upper end of the mounting cylinder 1 is connected to a pressure regulating assembly through an air pipe 4. The end of the air pipe 4 away from the mounting cylinder 1 is connected to the air source of the external stamping equipment. The lower side of the upper end of the lifting column 3 is connected to a top spring 5, and the lower end of the top spring 5 abuts against the lower end of the inside of the mounting cylinder 1. A dustproof component is provided on the upper surface of the pressure plate body 2 corresponding to the outside of the lifting column 3.

[0026] Example 2

[0027] Reference Figure 1-6 , while other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is:

[0028] The pressure regulating assembly includes a pressure gauge 6 and a pressure relief valve 7. A bypass pipe is provided on the pipe body of the air pipe 4. The pressure gauge 6 and the pressure relief valve 7 are both installed on the bypass pipe. The setting of the pressure regulating assembly allows the pressure plate body 2 to press the workpiece. If the air source of the external equipment fails and the pressure inside the mounting tube 1 is too high, the excess gas will flow out from the pressure relief valve 7, thereby preventing the mounting tube 1 from being damaged by the air pressure, that is, achieving a certain degree of air pressure regulation effect. At the same time, through the setting of the pressure gauge 6, it is convenient for personnel to monitor the internal pressure of the mounting tube 1, so as to adjust the internal pressure of the mounting tube 1 according to the stamping requirements.

[0029] A guide rod 8 is fixed to the upper end of the interior of the mounting cylinder 1, and a matching guide hole is provided inside the lifting column 3 corresponding to the guide rod 8. A matching air leakage hole is provided inside the lifting column 3 corresponding to the guide hole, and the upper end of the air leakage hole 10 extends to the outer wall of the upper end of the lifting column 3. Annular contact pads 9 are installed on the inner and outer sides of the upper end of the lifting column 3. The contact pads 9 are soaked with lubricating oil. The upper end of the lifting column 3 contacts the inner wall of the mounting cylinder 1 and the outer wall of the guide rod 8 through the contact pads 9. An oil storage tank 11 is provided corresponding to the contact pads 9 at the upper end of the lifting column 3. Lubricating oil is provided in the oil storage tank 11. The contact pads 9 are provided with a suction core 12 corresponding to the oil storage tank 11. The provision of the guide rod 8 improves the stability of the lifting column 3 when it moves up and down to a certain extent, and the provision of the contact pads 9 lubricates the inner wall of the mounting cylinder 1 and the outer wall of the guide rod 8 when the lifting column 3 moves up and down, so as to ensure the smooth operation of the lifting column 3. In order to keep it smooth for a long time, thereby avoiding the jerkyness between the three and causing them to wear too quickly, and the lubricating oil is the existing lubricating oil for the cylinder. The setting of the oil storage tank 11 and the suction core 12 is convenient for replenishing the lubricating oil in the contact pad 9, and the setting of the air bleed hole 10 is convenient for timely releasing or inhaling the gas in the guide hole when the lifting column 3 moves up and down, thereby avoiding affecting the up and down movement of the lifting column 3; the dustproof component includes a protective cylinder 13 and a wiping ring 14, the upper end of the protective cylinder 13 is slidably sleeved on the outside of the mounting cylinder 1 through the wiping ring 14, and the lower end of the protective cylinder 13 is mounted on the upper surface of the pressure plate body 2. The setting of the dustproof component prevents external dust from adhering to the outer ring surface of the lifting column 3, thereby reducing the phenomenon of dust entering the interior of the mounting cylinder 1 and causing abnormal wear between the mounting cylinder 1 and the lifting column 3.

[0030] Principle and advantages of use: During use of the utility model, the upper end of the mounting cylinder 1 is mounted on an external stamping device, and then when it is necessary to stamp the automobile chassis parts, the personnel place the parts to be stamped under the pressure plate body 2, and then control the movement of the lifting column 3 through the air source on the external stamping equipment, that is, when the air source inputs gas into the interior of the mounting cylinder 1, the gas inside the mounting cylinder 1 increases, thereby increasing the air pressure and gradually pushing the lifting column 3 downward until the lifting column 3 pushes the pressure plate body 2 to abut against the upper surface of the parts below. At this time, the air continues to be supplied to the interior of the mounting cylinder 1 through the external air source, that is, the internal pressure of the mounting cylinder 1 increases, thereby increasing the clamping pressure of the pressure plate body 2 on the parts accordingly, thereby achieving the effect of fixing the automobile chassis parts.

[0031] At the same time, in the above process, when it is necessary to stamp automobile chassis parts of different thicknesses, that is, it is necessary to adjust the clamping thickness of the pressure plate body 2, it is only necessary to adjust the gas volume of the mounting cylinder 1, that is, when the internal pressure of the mounting cylinder 1 remains unchanged, the up and down movement distance of the lifting column 3 is controlled by adjusting the gas volume, and when the movement distance of the lifting column 3 remains unchanged, the pressure applied to the parts by the pressure plate body 2 is controlled by adjusting the gas volume; in summary, when the pressure plate component proposed in this scheme is used, the pressure plate body 2 is pneumatically driven by a traditional push-pull electromagnet, and thus compared with the traditional scheme, this scheme is not only convenient for adjusting the adaptability of the pressure plate body 2 to the thickness of automobile chassis parts, but also in the long-term high-frequency working process, the mounting cylinder 1 and the lifting column 3 are not easily damaged by heat accumulation, and the structure is simple and not prone to failure.

[0032] It should be further explained that the setting of the pressure regulating assembly allows excess gas to flow out from the pressure relief valve 7 when the internal pressure of the mounting cylinder 1 is too high, thereby preventing the mounting cylinder 1 from being damaged by the air pressure, that is, achieving a certain degree of air pressure regulation effect. At the same time, the setting of the pressure gauge 6 allows personnel to monitor the internal pressure of the mounting cylinder 1 so as to adjust the internal pressure of the mounting cylinder 1 according to the stamping requirements; the setting of the guide rod 8 improves the stability of the lifting column 3 when it moves up and down to a certain extent, and the setting of the contact pad 9 lubricates the inner wall of the mounting cylinder 1 and the outer wall of the guide rod 8 when the lifting column 3 moves up and down, so as to ensure the smooth operation of the lifting cylinder 1. In order to keep it smooth for a long time, thereby avoiding the jerkyness between the three and causing excessive wear, and the lubricating oil is the existing lubricating oil for the cylinder. The setting of the oil storage tank 11 and the suction core 12 is convenient for replenishing the lubricating oil in the contact pad 9. The setting of the air bleed hole 10 is convenient for timely releasing or inhaling the gas in the guide hole when the lifting column 3 moves up and down, thereby avoiding affecting the up and down movement of the lifting column 3; the setting of the dustproof component prevents external dust from adhering to the outer ring surface of the lifting column 3, thereby reducing the phenomenon of dust entering the interior of the mounting tube 1 and causing abnormal wear between the mounting tube 1 and the lifting column 3.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
