Description
Technical Field
[0001] The invention relates to the technical field of automobile production, and in particular to a hydraulic buffer device for a clamp block of an automobile. Background Art
[0002] In the process of automobile welding production, welding fixtures have become important tools to improve production efficiency and reduce production costs. The basic structure of the welding fixture consists of a table, a support, an L-plate, a reference pin, a reference surface, a clamping mechanism, etc. On some fixtures, heavy-duty pressure blocks are required to ensure the quality of welding products. The traditional design of such heavy-duty pressure blocks uses a simple clamping structure, but requires operators to have a relatively large force to close and open the operation, which is prone to safety hazards and product quality problems. Summary of the invention
[0003] In view of the defects in the prior art, the purpose of the present invention is to provide a hydraulic buffer device for an automobile clamp block, and to add a hydraulic valve auxiliary device to a welding fixture that requires a heavy clamping arm, so as to achieve the purpose of saving effort when opening and closing the clamping arm.
[0004] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:
[0005] A hydraulic buffer device for a pressing block of an automobile clamp, characterized in that the device comprises a base, a cylinder, a hydraulic valve, a pressing arm and a clamping mechanism; the cylinder is located above the base and is connected to the pressing arm, the hydraulic valve is connected to the back of the base through a connecting block, and the hydraulic valve and the pressing arm are connected through a connecting rod; the clamping mechanism comprises a pressing arm, a pressing unit and a limit block, the limit block is located at the inner end of the pressing arm, and the clamping mechanism is connected to the pressing arm through a movable connecting block; the outer end of the pressing arm is connected to the pressing unit, the pressing unit is provided with a first pressing block and a positioning pin to position the product, and the middle section of the pressing arm is provided with a second pressing block.
[0006] Preferably, the first pressing block, the second pressing block and the positioning pin are designed to match the corresponding product shape.
[0007] Compared with the prior art, the automobile clamp pressure block hydraulic buffer device provided by the present invention can, when in use, provide buffering force for the hydraulic valve installed on the clamping arm with heavier tooling clamp requirements, and effectively realize the easy closing and opening of the clamping arm, which can not only reduce the labor intensity of employees, but also ensure the production line rhythm and quality requirements. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Other features, objects and advantages of the present invention will become more apparent from the detailed description of non-limiting embodiments made with reference to the following drawings:
[0009] Figure 1 It is a structural schematic diagram of the hydraulic buffer device of the automobile clamp pressing block in the embodiment in the open state;
[0010] Figure 2 A schematic structural diagram of the closed state of the hydraulic buffer device of the automobile clamp pressing block in this embodiment. DETAILED DESCRIPTION
[0011] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0012] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0013] It should be noted that similar numbers and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in the subsequent figures. In addition, all directional indications in this application (such as up, down, left, right, front, back, bottom...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the descriptions involving "first", "second", etc. in the application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.
[0014] like Figure 1 , Figure 2As shown, they are schematic diagrams of the structure of the hydraulic buffer device of the automobile clamp pressing block in the open state and the closed state in this embodiment, respectively. The device includes a base 1, a cylinder 2, a hydraulic valve 4, a clamping arm 6 and a clamping mechanism. The base 1 is used to connect and fix the device on the jig substrate. When the operator needs to perform welding product operations, the jig device is closed. The cylinder 2 is located above the base 1, and the clamping arm 6 is connected to the cylinder 2. The hydraulic valve 4 is connected to the back of the base 1 through the connecting block 3, and the hydraulic valve 4 and the clamping arm 6 are connected through the connecting rod 5. The clamping mechanism includes a pressing arm 8, a clamping unit 9 and a limit stopper 13. The limit stopper 13 is located at the inner end of the pressing arm 8, and the clamping mechanism is connected to the pressing arm 6 through the movable connecting block 7. The outer end of the pressing arm 8 is connected to the clamping unit 9, and the clamping unit 9 is provided with a first clamping block 11 and a positioning pin 10 to position the product. The middle section of the pressing arm 8 is provided with a second clamping block 12. The first pressing block 11, the second pressing block 12 and the positioning pin 10 are designed to match the corresponding product shapes.
[0015] After closing the tooling fixture device, the operator rotates the pressing arm 8 downward to position and fix the product sheet metal. At this time, the hydraulic valve 4 provides a buffer force to rotate the clamping arm 6. When the movable connecting block 7 reaches the position of the limit stop block 13, the positioning pin 10 with the clamping unit 9 enters the product for positioning; the operator presses the clamp switch to make the cylinder 2 rise and keep the first clamping block 11 and the second clamping block 12 tightly fitted, clamping the product sheet metal to fix it, and the employee performs welding operations, effectively closing the clamp device to reduce the labor intensity of employees.
[0016] When the operator has finished welding, he will operate to open the fixture device. During operation, turn on the fixture switch, and the employee will grab the pressing arm 8 and lift it up, so that the positioning pin 10, the first pressing block 11 and the second pressing block 12 will be separated from the fitted product sheet metal, and the limit block will be separated from the movable connection block 7; the pressing arm 6 will rotate and move backward, and the hydraulic valve 4 equipped with the connection block 3 will assist in providing buffering force to ensure the easy movement of the pressing arm 6, thereby effectively opening the fixture device and reducing the labor intensity of employees.
[0017] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention.
