Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile manufacturing equipment, and in particular relates to a pinning cylinder mechanism used in automobile welding production. Background Art
[0002] Fixtures are the focus of welding workshops and the foundation of the precision of the body in white. A set of fixtures has many positioning points, mainly divided into positioning pins, clamps, and pin-out cylinders. The pin-out cylinder has both clamping and positioning pin functions. It directly affects the positioning accuracy of the fixtures.
[0003] In automotive tooling fixtures, the frequency of use of the detent cylinder is very high, especially in the process positioning, which is basically a detent cylinder mechanism added to the NC. Good detent strength and large clamping force are the regular requirements for the detent cylinder.
[0004] Currently, the detent cylinders in the fixture are mainly purchased, but the cycle is long, the price is high, and the positioning diameter cannot be less than 16mm, which has become a pain point in the design of fixture tooling. Utility Model Content
[0005] The utility model aims to provide a detent cylinder mechanism for automobile welding production to solve the problems existing in the prior art.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hook pin cylinder mechanism for automobile welding production, characterized in that it includes a positioning pin, a support block, a hook, a mounting bracket and a cylinder; the cylinder is fixed to the bottom of the mounting bracket, the piston rod of the cylinder does not extend from the mounting bracket and is hinged to one end of the hook, the middle part of the hook is hinged to the support block through a first hinge pin, the lower part of the support block is fixed to the upper part of the mounting bracket, the middle parts of the support block and the positioning pin are both provided with through grooves, the hook moves in the through grooves, and the positioning pin is fixed to the top of the support block.
[0007] Preferably, the upper end of the hook extends out from and retracts from a side of the positioning pin.
[0008] Preferably, the piston rod of the cylinder is provided with a cylinder head, and the cylinder head is hinged to one end of the hook via a second hinge pin.
[0009] The beneficial effect of the utility model is that the device converts the output force of the cylinder into the clamping force of the hook, and the extension and retraction of the cylinder realize the clamping and opening functions of the hook. It can be positioned, and the clamping force of the positioning hole with a pin diameter of 15mm can reach 62 kg. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 It is a schematic diagram of the clamping state of the overall structure of the present invention;
[0012] Figure 3 It is a schematic diagram of the overall structure of the present invention in an open state;
[0013] Numbers in the figure: 1 positioning pin, 2 first hinge pin, 3 second hinge pin, 4 hook, 5 cylinder head, 6 mounting bracket, 7 cylinder, 8 support block. DETAILED DESCRIPTION
[0014] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.
[0015] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0016] like Figure 1 As shown, a hook cylinder mechanism for automobile welding production includes a locating pin 1, a support block 8, a hook 4, a mounting bracket 6 and a cylinder 7, wherein the cylinder is fixed to the bottom of the mounting bracket, the piston rod of the cylinder does not extend from the mounting bracket and is hinged to one end of the hook, the middle part of the hook is hinged to the support block through a first hinge pin, the lower part of the support block is fixed to the upper part of the mounting bracket, the middle parts of the support block and the locating pin are both provided with through grooves, the hook moves in the through grooves, and the locating pin is fixed to the top of the support block.
[0017] like Figure 2 and Figure 3 As shown, in the specific implementation, the clamping and loosening of the plate is performed according to the following process:
[0018] Clamping: manually place the plate, walk to the button side and press the button, the cylinder 7 extends, and the cylinder head 5 also extends, and the extended cylinder head 5 drives the hook 4 positioned by the first hinge pin 2 and the second hinge pin 3 to press downward, so as to realize the pressing of the plate.
[0019] Opening: Manually walk to the button side and press the button, the cylinder 7 retracts, and the cylinder head 5 also retracts, and the retracted cylinder head 5 drives the hook 4 positioned by the first hinge pin 2 and the second hinge pin 3 to open upward. Manually take out the panel and go to the next step.
[0020] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
