Description

Technical Field

[0001] The utility model relates to the field of riveting equipment, in particular to an auxiliary positioning type riveting mechanism. Background Art

[0002] Common riveting equipment currently available usually requires operators to hold the riveting gun, move the riveting gun to the working position, and then manually pull the trigger to complete the riveting action. Since there is no limit or reference to the moving position and range of the riveting gun, and there is no restriction on the action of pulling the trigger, the operator can perform the riveting action at any position, which often leads to unqualified riveting problems. Utility Model Content

[0003] The utility model aims to solve the above problems and provides an auxiliary positioning type riveting mechanism, the technical solution adopted by the utility model is as follows:

[0004] An auxiliary positioning riveting mechanism comprises two perpendicular X-axis slide rails, a Y-axis slide rail and a Z-axis slide rail, wherein the Y-axis slide rail slides on the X-axis slide rail, and the Z-axis slide rail is arranged in a vertical direction and slides on the Y-axis slide rail; a mobile frame is slidably arranged on the Z-axis slide rail, and a rivet gun is installed on the mobile frame; and a limiting clamping mechanism is also included, wherein the limiting clamping mechanism comprises a limiting rod, and the limiting rod moves synchronously with the mobile frame, and when the mobile frame moves downward to a working position, the limiting clamping mechanism fixes the relative position of the limiting rod and the Z-axis slide rail.

[0005] On the basis of the above scheme, the limit pressing mechanism also includes a fixed frame, which is fixedly mounted on the Z-axis slide rail, the fixed frame is fixedly connected to the mounting frame, the limit rod passes through the mounting frame, the mounting frame is fixedly connected to the cylinder body of the clamping cylinder, a limit detection sensor for detecting the position of the limit rod is arranged on the fixed frame, a clamping connecting rod is hinged between the end of the piston rod of the clamping cylinder and the limit rod, and a hinged rod is hinged between the middle part of the clamping connecting rod and the cylinder body of the clamping cylinder.

[0006] Based on the above solution, the limit detection sensor is a displacement sensor.

[0011] Based on the above solution, the number of the balancers is 2, and they are symmetrically arranged on opposite sides of the Z-axis slide rail.

[0012] The beneficial effects of the utility model are as follows: the moving position and range of the rivet gun are limited by the three-way orthogonal slide rails; the rivet gun is arranged on the slide rails and is used in conjunction with the limit rod and the limit detection sensor to accurately determine the working position of the rivet gun, eliminate the gap between the rivet gun head and the product, and ensure the quality of riveting; the rivet gun can automatically perform the riveting action only after it reaches the working position, preventing the operator from causing problems such as premature riveting due to technical level or accidental touch.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0020] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0021] like Figures 1 to 4 As shown, an auxiliary positioning type riveting mechanism includes two vertical X-axis slide rails 11, Y-axis slide rails 12 and Z-axis slide rails 13, wherein the Y-axis slide rail 12 slides on the X-axis slide rail 11, and the Z-axis slide rail 13 is arranged in the vertical direction and slides on the Y-axis slide rail 12; a mobile frame 21 is slidably arranged on the Z-axis slide rail 13, and a rivet gun 41 is installed on the mobile frame 21, so as to realize the movement of the rivet gun 41 in space. Preferably, a balancer 22 is arranged on the Z-axis slide rail 13, and a pull ring 23 for connecting with the balancer 22 is arranged on the mobile frame 21. By arranging the balancer 22, the mobile frame 21 and the rivet gun 41 have a certain lifting effect, thereby reducing the labor intensity of the operator during the supporting and moving process. The number of the balancers 22 is 2, and they are symmetrically arranged on the opposite sides of the Z-axis slide rail 13, so as to achieve the effect of balancing and symmetrical lifting.

[0022] The limit clamping mechanism also includes a limit rod 33, which is fixedly connected to the moving frame 21 through a fixing block 38 and moves synchronously with the moving frame 21. When the moving frame 21 moves downward to the working position, the limit clamping mechanism fixes the relative position of the limit rod 33 and the Z-axis slide rail 13. Specifically, as Figure 3 As shown, the position limiting and clamping mechanism also includes a fixing frame 31, the fixing frame 31 is fixedly mounted on the Z-axis slide rail 13, the fixing frame 31 is fixedly connected to the mounting frame 32, the position limiting rod 33 passes through the mounting frame 32, the mounting frame 32 is fixedly connected to the cylinder body of the clamping cylinder 35, and a position limiting detection sensor 34 for detecting the position of the position limiting rod 33 is arranged on the fixing frame 31, preferably, the position limiting detection sensor 34 is a displacement sensor. A clamping connecting rod 36 is hinged between the end of the piston rod of the clamping cylinder 35 and the position limiting rod 33, and a hinged rod 37 is hinged between the middle part of the clamping connecting rod 36 and the cylinder body of the clamping cylinder 35. When the limit detection sensor 34 detects that the limit rod 33 moves to the predetermined position, it indicates that the movable frame 21 drives the rivet gun 41 to move to the working position or working height, the clamping cylinder 35 is actuated, and the piston rod is extended to press the limit rod 33 downward, thereby fixing the position of the limit rod 33 in the Z-axis direction, and then fixing the position of the movable frame 21, so that the gun head of the rivet gun 41 abuts against the product surface to avoid a gap between the gun head and the product.

[0023] The trigger mechanism 42 is also included. The trigger mechanism 42 is installed on the mobile frame 21. The trigger mechanism 42 is a cylinder, and the cylinder action component is arranged at the trigger position of the rivet gun 41, and the trigger position is wrapped to prevent the operator from accidentally touching the trigger to cause the rivet action; the trigger mechanism 42 is connected to the limit clamping mechanism signal. When the clamping cylinder 35 fixes the position of the limit rod 33 and the mobile frame 21, the trigger mechanism 42 receives the signal and acts, and the trigger is pulled to complete the automatic riveting.

[0024] The mobile frame 21 also includes a waste nail storage bin 45, which is connected to the rivet gun 41 through a waste nail discharge pipe 43 to store waste nails generated by rivet pulling to avoid random discharge. Preferably, the waste nail discharge pipe 43 is connected to an annular sensor 44 for detecting whether waste nails have passed through. When the annular sensor 44 detects that waste nails have passed through, it proves that the riveting action has been completed, and transmits the action completion signal to the limit clamping mechanism, the clamping cylinder 35 is actuated, the piston rod is recovered, and the position fixation of the mobile frame 21 and the limit rod 33 is released, so that the mobile frame 21 can continue to move to the next working position.

[0025] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
