Description

Technical Field

[0001] The present invention relates to the technical field of medical bed welding, and in particular to a welding device for producing medical beds. Background Art

[0002] When medical beds are actually produced and manufactured, welding is an important processing method. During actual welding, welding clamping brackets are usually used to limit the four frames, horizontal braces, and vertical braces of the bed to ensure welding stability and welding accuracy. The current welding devices for medical bed production are not convenient for limiting the horizontal braces and vertical braces to be installed in place before welding when welding and clamping the horizontal braces and vertical braces. Direct welding without the horizontal braces or vertical braces in place will directly affect the welding accuracy, affect the flatness of the bed surface, and cause rework and other problems.

The structure is simple and convenient to operate. The magnetic positioning method using the vertical support electromagnet 203 and the horizontal support electromagnet 204 will not be completely tightened, which can facilitate the sliding of the horizontal support or the vertical support for fine-tuning, ensuring flexibility of use. The vertical support electromagnet 203 is used to magnetically attract two vertical supports. At this time, the magnetically attracted vertical support can press the vertical support switch 202, and then a row of horizontal supports are placed on the limit seat 201, and the horizontal support switch 205 is pressed through the cross bar to ensure that the horizontal support and the vertical support are installed in place.

[0039] like Figures 2 to 6As shown, the frame limit member 3 includes four limit mounting blocks 301 fixedly mounted at the four corners of the clamping mounting plate 101; the four limit mounting blocks 301 have the same structure; diagonal limit columns 302 are slidably mounted on the limit mounting blocks 301, and the ends of the diagonal limit columns 302 are arc-shaped structures; the tails of the diagonal limit columns 302 are fixedly mounted with retraction springs 303, and the retraction springs 303 at the tails of the diagonal limit columns 302 are connected to the interior of the limit mounting blocks 301; The diagonal limit column 302 is used to limit the corners of the bed frame; the frame limit member 3 also includes a limit electromagnet 304 fixedly mounted on the limit mounting block 301; the limit electromagnet 304 is electrically connected to the horizontal support switch 205 and the vertical support switch 202; the limit mounting block 301 is slidably connected to the limit shaft 305; a spring is fixedly mounted on the top of the limit shaft 305, and the spring at the top of the limit shaft 305 is connected to the bottom of the limit electromagnet 304; the top of the limit shaft 305 The spring is located inside the limit mounting block 301; the limit shaft 305 is used to stop the diagonal limit column 302; the frame clamping part 4 includes four frame clamping plates 401 fixedly mounted on the clamping mounting plate 101, and the cross-sections of the four clamping mounting plates 101 are L-shaped structures; the two opposite frame clamping plates 401 of the four frame clamping plates 401 are of the same length; the frame clamping plate 401 is used to place the bed frame; the four frame clamping plates 401 are respectively fixedly mounted with threaded connection blocks 4011; the four threaded connection blocks 4011 are respectively provided with threaded holes; the bottoms of the threaded holes on the four threaded connection blocks 4011 are respectively sleeved with clamping switches 402; the four clamping switches 402 are respectively electrically connected to the welding power supply; the frame clamping part 4 also includes fastening studs 403 threadedly connected to the threaded holes on the four threaded connection blocks 4011; the ends of the four fastening studs 403 are respectively pressed and fitted with the four clamping switches 402;A pressure plate 404 is fixedly installed on the top of the four fastening studs 403, and the four pressure plates 404 are used to press the bed frame respectively. The frame limiter 3 can cooperate with the frame clamping member 4 to realize automatic control to ensure that the bed frame can be installed only after the installation of the horizontal brace and the vertical brace is completed. At the same time, the bed frame needs to be clamped in place before the welding machine power supply can be normally controlled to start and the welding work can be carried out normally. This can avoid the staff forgetting to install local horizontal braces or vertical braces, and the horizontal brace or vertical brace is not installed in place, which can ensure the welding quality and avoid the need for manual maintenance due to local missing parts. It can ensure the rationality of this structure, improve practicality, and ensure the quality of welding after one-time forming. At the same time, this structure can realize non-sensing operation when the staff normally installs the horizontal brace or vertical brace, without affecting the installation efficiency. The structure is simple and flexible, and can realize automatic limit control. This structure requires that all horizontal or vertical supports are installed in place. At this time, all vertical support switches 202 and horizontal support switches 205 are squeezed. Only then can the limit electromagnet 304 be controlled to move the magnetic limit shaft 305 upward and no longer block the diagonal limit column 302. At this time, the diagonal limit column 302 is no longer blocked, and the staff can normally place the bed frame on the frame clamping plate 401. During the process, the bed frame can squeeze the diagonal limit column 302, compressing the retraction spring 303. After the bed frame is placed on the frame clamping plate 401, the fastening stud 403 can be tightened to drive the pressure plate 404 to squeeze the bed frame. At this time, the fastening stud 403 can squeeze the clamping switch 402, control the welding machine power supply to be turned on, and the welding work can be carried out normally. The operation is simple.

[0040] like Figures 2 to 6As shown, the weld reminder member 5 includes four rows of fixing plates 501 fixedly mounted on the four frame clamping plates 401, and the four rows of fixing plates 501 correspond to the two ends of the horizontal support and the vertical support respectively; the fixing plates 501 are conductors; the weld reminder member 5 also includes four rows of weld spring clips 502 fixedly mounted on the four frame clamping plates 401; the four rows of weld spring clips 502 are aligned with the fixing plates 501 respectively; the four rows of weld spring clips 502 are inclined spring clip structures; the sides of the four rows of weld spring clips 502 are used to elastically fit the two ends of the horizontal support and the vertical support respectively; the four rows of weld spring clips 502 are installed obliquely; the reminder light strip 102 is electrically connected to the four rows of weld spring clips 502 and the fixing plates 501, and the weld reminder member 5 can utilize the weld spring clips 5 02 Auxiliary elastic fitting is used to elastically space the two ends of the horizontal bar or vertical bar, which can assist in spacing out the welds and ensure the welding quality. At the same time, the weld spring clips 502 and the prompt light strip 102 can be used to improve the consistency of the welds at both ends of the horizontal bar or vertical bar, further ensuring the welding effect, and can provide intuitive prompts. The structure is simple and convenient to operate. After the horizontal bar or vertical bar is placed on the limit seat 201, the side surfaces of each weld spring clip 502 are used to elastically fit the two ends of the horizontal support and the vertical support respectively. Once the consistency deviation of the welds at both ends of the local horizontal support or vertical support exceeds the standard, that is, the weld at one end is narrow and the weld at the other end is wide, the corresponding lamp beads on the prompt light strip 102 will not be able to light up for prompting, which can facilitate the staff to be informed in time.

[0041] The working principle provided by the present invention is that first, the bolt mounting groove 1011 is used to pass the bolt to be installed on the work surface, first the vertical support is placed on the limit seat 201, and the vertical support electromagnet 203 is used to magnetically attract the two vertical supports. At this time, the magnetically attracted vertical support can press the vertical support switch 202, and then a row of horizontal supports are placed on the limit seat 201, and the horizontal support switch 205 is pressed by the cross bar to ensure that the horizontal supports and vertical supports are installed in place; after all the horizontal supports or vertical supports are installed in place, all the vertical support switches 202 and horizontal support switches 205 are squeezed, and only then can the limit electromagnet 304 be controlled to magnetically attract the limit shaft 305 to move up and no longer block the diagonal limit column 302. At this time, the diagonal limit column 302 is no longer blocked, and the staff can normally place the bed frame on the frame clamping plate 401. During the process, the bed frame can squeeze the diagonal limit column 302 and compress the retraction spring 303, as shown in the attached figure. Figure 6As shown, on the contrary, once the local vertical support switch 202 or the horizontal support switch 205 is not squeezed, the spring at the top of the limit shaft 305 is squeezed, and the limit shaft 305 can limit the stop at the tail of the diagonal limit column 302. At this time, the bed frame cannot be placed normally on the frame clamping plate 401. After the bed frame is placed on the frame clamping plate 401, the fastening stud 403 can be tightened to drive the pressure plate 404 to squeeze the bed frame. At this time, the fastening stud 403 can squeeze the clamping switch 402 to control the welding machine motor. Once the power source is turned on, welding work can be carried out normally; after the horizontal bar or vertical bar is placed on the limit seat 201, the sides of each welding spring piece 502 are used to elastically fit the two ends of the horizontal support and the vertical support respectively. Once the consistency deviation of the welds at both ends of the local horizontal support or vertical support exceeds the standard, that is, the weld at one end is narrow and the weld at the other end is wide, the side of the wide weld cannot effectively squeeze the welding spring piece 502 to fit the fixing piece 501, and the circuit here cannot be conducted, and the corresponding lamp beads on the prompt light strip 102 cannot light up to provide a prompt.

[0042] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
