Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts production equipment, in particular to a material car quick-change fixing device. Background Art
[0002] In the automated welding production process of automotive parts, especially the welding of flat plates with patch plates, many parts need to be loaded into special containers. Special containers need to be prepared for special products. With the increasing degree of automation, the production rhythm and related auxiliary equipment requirements are also correspondingly improved, especially for the products to be loaded into fixed containers after welding. In the past, in automated production lines, the finished products were manually loaded into containers and moved using forklifts, hydraulic trucks and other related auxiliary equipment. Although this method can meet the turnover of containers, it wastes the rhythm of automated production equipment and causes equipment downtime waiting time. In order to quickly meet the unloading problem of the automated production line and save the time wasted in moving the unloading container of the production line, a material cart quick-change fixing device is made according to the needs of the automated production line and combined with the structure of the material cart.

BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 The utility model provides a schematic structural diagram of a material cart quick-change fixing device.
[0013] Figure 2 for Figure 1 A top view of a trolley quick-change fixture. DETAILED DESCRIPTION
[0014] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.
[0015] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of a material cart quick-change fixing device provided by the utility model. The material cart quick-change fixing device includes a base plate 10, a guide portion 20 arranged on the base plate 10, and a limit portion 30 arranged on the base plate 10 and located on one side of the length of the guide portion 10. It can be imagined that the material cart quick-change fixing device also includes some other functional structures, such as rollers, a frame, etc., which are well known to those skilled in the art and will not be repeated here.
[0016] The bottom plate 10 includes a bottom plate body 11 and two groups of mounting holes 12 respectively arranged on the length side end surfaces of the bottom plate body 11. The bottom plate body 11 is made of iron plate and is fixed on the ground through the mounting holes 12 on both sides.
[0017] The guide portion 20 includes two guide plates 21 disposed opposite to each other along the central axis of the base plate body 11 in the length direction, and a pedal assembly 22 disposed at an end of the guide plate 21 facing away from the limiting portion 30 .
[0018] In this embodiment, the guide plate 21 is screwed into the base plate body 11 for easy replacement. A guide surface 23 is provided at one end of each guide plate 21 facing the pedal assembly 22, and the guide surface 23 is integrated with the guide plate 21, so that the guide wheel on the material cart is located between the two guide plates 21, thereby guiding the material cart. The pedal assembly 22 is clamped between the two guide plates 21, so that the operator can lift the material cart clamped between the two guide plates 21 by stepping on the pedal assembly 22. And when the guide wheel passes through the pedal assembly 22, the pedal assembly 22 can also play a limiting role. The pedal assembly 22 is an existing device on the market and will not be described in detail here.
[0019] The limiting portion 30 includes a pair of supports 31 spaced apart on one end of the base body 11 away from the pedal assembly 22, two limiters 32 respectively arranged on the end surfaces of the two supports 31 facing the guide plate 21, and a touch switch 33 arranged on one side of the supports 31.
[0020] The two supports 31 are arranged on both sides of the end of the bottom plate body 11, and the end faces of the two supports 31 are perpendicular to the guide plate 21. The stopper 32 is arranged at one end of the support 31 away from the bottom plate body 11 to play a buffering role.
[0021] The touch switch 33 is arranged toward the guide plate 21, and the spacing distance between the touch switch 33 and the guide plate 21 is smaller than the spacing distance between the limiter 32 and the guide plate 21, so as to ensure that the material cart can preferentially trigger the touch switch 33 when it moves to the end along the guide plate 21. The touch switch 33 identifies whether the material cart is in place, thereby transmitting a signal to the automated production line so that the automated production line can resume production.
[0022] When in use, the operator inserts the material cart between the two guide plates 21 and pushes it in until it touches the touch switch 33, and fixes the material cart between the two guide plates 21 for the automated production line to take materials. When replacing the material cart, the operator drags the material cart so that the material wheel is located on the pedal assembly 22, steps on the pedal assembly 22 to lift the material cart, and the operator pulls out the material cart and pushes in a new one to complete the replacement of the material cart.
[0023] Compared with the prior art, the utility model provides a trolley quick-change fixing device which guides the trolley by setting the guide part 20, and sets the limit part 30 to fix the trolley in the guide part 20. The guide part 20 includes two guide plates 21 arranged relatively along the central axis of the length direction of the base plate body 11, and a pedal assembly 22 arranged in the end of the guide plate 21 facing away from the limit part 30. The limit part 30 includes a pair of supports 31 arranged at intervals on the end of the base plate body 11 away from the pedal assembly 22, two limiters 32 respectively arranged on the end faces of the two supports 31 facing the guide plates 21, and a touch switch 33 arranged on one side of the support 31. The two guide plates 21 guide the trolley to move axially along the two guide plates 21, the limiter 32 is set to limit the moving range of the trolley, and the touch switch 33 is set to improve the automation of the production line and improve production efficiency.
[0024] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
