Description

Technical Field

[0001] This application relates to the technical field of welding auxiliary equipment, and in particular to a welding tooling for press-fitting a cover plate. Background Art

[0002] During the installation of some electrical components on a mobile phone, a welded press-fitting cover plate needs to be used for press-fitting. When welding the press-fitting cover plate, it is necessary to fix the press-fitting cover plate on the welding tooling to facilitate the worker to perform welding.

[0003] Existing welding tooling generally includes a support base, a plurality of positioning posts and a plurality of positioning plates. The plurality of positioning posts are arranged at intervals on the support base. The bottom ends of the positioning posts are screwed to the support base, and a positioning plate is connected to the top end of each positioning post. After placing the press-fitting cover plate on the support base, the user can rotate the positioning posts around the press-fitting cover plate to abut the press-fitting cover plate between the positioning plates, thereby realizing the positioning of the press-fitting cover plate.

[0004] However, after long-term use, the threaded connection between the positioning post and the support base is prone to wear, making it easy for the positioning post and the support base to rotate relative to each other, resulting in poor positioning effect of the welding tooling, affecting the welding effect of the press-fitting cover plate, and thus making the press-fitting cover plate unable to be used for press-fitting electrical components.

[0005] In view of this, a welding tooling for press-fitting a cover plate is needed. Utility Model Content

[0006] In order to solve the problem that the existing welding tooling has a poor positioning effect after long-term use, which in turn affects the welding effect of the press-fitting cover plate, making the press-fitting cover plate unable to be used for press-fitting electrical components, this application provides a welding tooling for press-fitting a cover plate.

[0007] This application provides a welding tooling for press-fitting a cover plate, adopting the following technical solution: including a support base, a pressing block and a driving device. A positioning protrusion is provided on the press-fitting cover plate, a positioning groove adapted to the positioning protrusion is opened on the support base, the driving device is in transmission connection with the pressing block, and the driving device can drive the pressing block away from or close to the support base and abut the press-fitting cover plate between the pressing block and the support base.

[0008] By adopting the above technical solution, when the user places the press-fitting cover plate on the support seat, the positioning grooves formed on the support seat can cooperate with the positioning protrusions on the press-fitting cover plate to position the press-fitting cover plate. So that after the user adjusts the position of the press-fitting cover plate to enable the positioning protrusions to be inserted into the positioning grooves, the driving device can be activated to drive the pressing block close to the support seat, and the press-fitting cover plate can be fixed on the support seat by the pressing block, thereby realizing rapid and accurate positioning of the press-fitting cover plate; Since the positioning function of the positioning grooves will not fail after long-term use, the welding fixture for the press-fitting cover plate can also have a good positioning effect after long-term use, so that the welding effect of the press-fitting cover plate will not be affected by inaccurate positioning, ensuring that the press-fitting cover plate will not be unable to be used for press-fitting electrical components due to inaccurate positioning during the welding process.

[0009] Specifically, the positioning protrusions include a vertical protrusion and a horizontal protrusion. The length direction of the vertical protrusion is perpendicular to the length direction of the horizontal protrusion. The positioning grooves include a vertical positioning groove and a horizontal positioning groove. The vertical protrusion can be inserted into the vertical positioning groove and abut against the groove wall of the vertical positioning groove, and the horizontal protrusion can be inserted into the horizontal positioning groove and abut against the groove wall of the vertical positioning groove.

[0010] By adopting the above technical solution, the arrangement of the vertical positioning groove and the horizontal positioning groove enables the positioning groove to position the press-fitting cover plate in the horizontal direction, so as to enhance the positioning effect of the welding fixture for the press-fitting cover plate on the press-fitting cover plate.

[0011] Further, the support seat includes a base, a column and a support plate. The column is arranged above the base. The bottom of the support plate is connected to the top of the column. The mounting through hole and the positioning groove are formed on the plate surface of the support plate. The driving device is a driving cylinder. The cylinder body of the driving cylinder is arranged between the base and the support plate, and the piston rod of the driving cylinder passes through the mounting through hole and is connected to the pressing block.

[0012] By adopting the above technical solution, the driving cylinder can drive the pressing block close to the support plate to abut the press-fitting cover plate between the pressing block and the plate surface of the support plate, and can also drive the pressing block away from the support plate, so that the user can remove the press-fitting cover plate from the support plate.

[0013] Further, the driving device is a hydraulic rotary cylinder.

[0014] By adopting the above technical solution, while the piston rod of the hydraulic rotary cylinder descends, it can rotate and drive the pressing block to rotate to directly above the pressed cover plate, so as to be able to abut the pressed cover plate between the pressing block and the disk surface of the support disk; while the piston rod of the hydraulic rotary cylinder ascends, it can rotate and drive the pressing block to rotate away from directly above the pressed cover plate, so that the user can directly take away the pressed cover plate from the clearance vacated by the pressing block.

[0015] Further, it further includes a slag blocking member, and the slag blocking member is connected to the driving device and can block the gap between the piston rod and the cylinder block of the driving device.

[0016] By adopting the above technical solution, since during the welding process of the pressed cover plate, some metal debris will fall from the installation through hole to the gap between the cylinder block and the piston rod of the driving device, and then when the piston rod expands and contracts, these metal debris will scratch the rod body of the piston rod or be brought into the interior of the cylinder block of the driving device, resulting in damage to the driving device. The slag blocking member can block these metal debris so that the metal debris will not fall into the gap between the cylinder block and the piston rod of the driving device.

[0017] Further, the slag blocking member includes a soft slag blocking strip and a clamping member. Both ends of the soft slag blocking strip can be clamped via the clamping member to form an annular member, and this annular member is sleeved on the piston rod of the driving device. When the pressed cover plate is abutted between the pressing block and the support disk, the annular member is abutted between the pressing block and the cylinder block of the driving device.

[0018] By adopting the above technical solution, both ends of the soft slag blocking member can be clamped by the clamping member to form an annular member sleeved on the piston rod of the driving device, so that the soft slag blocking member can be sleeved on the piston rod of the driving device; and when the pressing block presses the pressed cover plate, the soft slag blocking member will be abutted between the pressing block and the cylinder block of the driving device, so as to be able to block the gap between the cylinder block and the piston rod of the driving device through the soft slag blocking member.

[0019] Further, the clamping member is a snap fastener, and the snap fastener includes a male snap and a female snap. The male snap is arranged at one end of the soft slag blocking strip, and the female snap is arranged at the other end of the soft slag blocking strip.

[0020] By adopting the above technical solution, the male snap can cooperate with the female snap to connect both ends of the soft slag blocking member.

[0021] Specifically, a buffer member is arranged at the bottom of the pressing block, and the buffer member can abut against the pressed cover plate.

[0022] By adopting the above technical solution, the buffer member can form a buffer between the pressing block and the pressed cover plate, so that the pressing block is not likely to damage the pressed cover plate.

[0023] In summary, the present application includes the following beneficial technical effects:

[0024] It includes a support base, a pressing block, and a driving device. The pressing cover plate is provided with a positioning protrusion, and the support base is provided with a positioning groove adapted to the positioning protrusion. The driving device is in transmission connection with the pressing block, and the driving device can drive the pressing block away from or close to the support base and press the pressing cover plate against the pressing block and the support base. When the user places the pressing cover plate on the support base, the positioning groove provided on the support base can cooperate with the positioning protrusion on the pressing cover plate to position the pressing cover plate, so that the user only needs to adjust the position of the pressing cover plate until the positioning protrusion can be inserted into the positioning groove, and then the driving device can be started to drive the pressing block close to the support base, so as to fix the pressing cover plate on the support base through the pressing block, thereby realizing rapid and accurate positioning of the pressing cover plate; since the positioning function of the positioning groove will not fail after long-term use, the welding tooling for the pressing cover plate can also have a good positioning effect after long-term use, so that the welding effect of the pressing cover plate will not be affected by inaccurate positioning, ensuring that the pressing cover plate will not be unable to be used for pressing electrical components due to inaccurate positioning during welding processing.

[0029] Figure 1 is a perspective view of a welding tooling for a pressing cover plate of the present application, Figure 2 is along Figure 1 a schematic cross-sectional view taken along the central axis of the piston rod of the driving device in Figure 1 andFigure 2 , a welding tooling for press-fitting a cover plate provided by the present application includes: a support base 1, six pressing blocks 2, six driving devices 3 and a slag blocking member 5. The support base 1 includes a base 12, four columns 13 and a support plate 14. The four columns 13 are respectively erected at the four end corners of the base 12. The bottom of the support plate 14 is screwed to the tops of the four columns 13. A plurality of bosses are formed at intervals on the plate surface of the support plate 14, and two vertical positioning grooves 111 and two horizontal positioning grooves 112 are formed between these bosses; the press-fitting cover plate 4 can be a frame structure composed of two vertical rods 41 and four cross plates 42. The two vertical rods 41 are arranged in parallel at intervals. The four cross plates 42 are arranged above the two vertical rods 41 in parallel at intervals along the width direction of the vertical rods 41. Each cross plate 42 is connected to the two vertical rods 41, and adjacent two cross plates 42 are also connected to each other and form 6 holes on the press-fitting cover plate 4; the two vertical rods 41 correspond to the two vertical positioning grooves 111 one by one. The rod bodies of the two vertical rods 41 form vertical protrusions, and each vertical rod 41 can be placed in a corresponding vertical positioning groove 111 and abutted against the inner wall of the vertical positioning groove 111. Raised structures adapted to the horizontal positioning grooves 112 are provided on the bottom surfaces of the two cross plates 42 at both ends of the press-fitting cover plate 4. The raised structures form horizontal protrusions. The two raised structures correspond to the two horizontal positioning grooves 112 one by one. Each raised structure can be inserted into a corresponding horizontal positioning groove 112 and abutted against the inner wall of the horizontal positioning groove 112.

[0030] See Figure 1 and Figure 2 , six mounting through holes are also formed on the plate surface of the support plate 14. Each mounting through hole corresponds to a hole on the press-fitting cover plate 4. Each driving device 3 corresponds to a mounting through hole. The driving device 3 can be a hydraulic cylinder. The cylinder body 32 of the driving device 3 is arranged between the base 12 and the support plate 14 and connected to the base 12. The piston rod 31 of the driving device 3 passes through a corresponding mounting through hole and is connected to one end of a pressing block 2. A buffer member 21 is provided at the end of each pressing block 2 away from the driving device 3. The buffer member 21 can be a rubber pad, so as to form a buffer between the pressing block 2 and the press-fitting cover plate 4 through the buffer member 21, so that the pressing block 2 is not easy to damage the press-fitting cover plate 4.

[0031] Preferably, the driving device 3 can be a hydraulic rotary cylinder. The piston rod 31 of the hydraulic rotary cylinder can rotate while descending and drive the pressing block 2 to rotate to directly above the press-fitting cover plate 4, so as to be able to abut the press-fitting cover plate 4 between the pressing block 2 and the plate surface of the support plate 14. While the piston rod 31 of the hydraulic rotary cylinder rises, it can rotate and drive the pressing block 2 to rotate away from directly above the press-fitting cover plate 4, so that the user can directly take away the press-fitting cover plate 4 from the gap vacated by the pressing block 2, thus facilitating the user to take away the press-fitting cover plate 4.

[0032] Figure 3 Yes Figure 2 is a schematic enlarged view of area A therein, showing the snap member. Refer to Figure 1 and Figure 3 , the slag baffle 5 includes a soft slag baffle strip 51 and a snap member 52. The soft slag baffle strip 51 can be a rubber strip, and the snap member 52 is a mother-and-son buckle 522. The mother-and-son buckle 522 includes a son buckle 521 and a mother buckle 522. The son buckle 521 is provided at one end of the soft slag baffle strip 51, and the mother buckle 522 is provided at the other end of the soft slag baffle strip 51, so that the two ends of the soft slag baffle strip 51 can be snapped through the snap member 52 to form an annular member, and the annular member can be sleeved on the piston rod 31 of the driving device 3.

[0033] It should be noted that during the welding and pressing of the pressing cover plate 4, some metal debris will fall from the installation through hole to the gap between the cylinder block 32 and the piston rod 31 of the driving device 3. Then, when the piston rod 31 expands and contracts, these metal debris will scratch the rod body of the piston rod 31 or be brought into the interior of the cylinder block 32 of the driving device 3, resulting in damage to the driving device 3. The user can determine how many layers of annular members need to be sleeved on the piston rod 31 of the driving device 3 according to the length of the piston rod 31 of the driving device 3 extending out of the cylinder block 32 when the pressing cover plate 4 is abutted between the pressing block 2 and the support disk 14. For example, when the thickness of the annular member is 1 cm and the length of the piston rod 31 of the driving device 3 extending out of the cylinder block 32 is 2.9 cm, the user can sleeve three layers of annular members on the piston rod 31, so that when the pressing block 2 presses the pressing cover plate 4, the three layers of annular members will be abutted between the pressing block 2 and the cylinder block 32 of the driving device 3 and undergo slight deformation, so that the three layers of annular members can well block the gap between the cylinder block 32 and the piston rod 31 of the driving device 3 and protect the driving device 3.

[0034] The usage steps of a welding tooling for a pressing cover plate of the present application are as follows:

[0035] The user can first place the pressing cover plate 4 on the support disk 14 and adjust the position of the pressing cover plate 4 so that both vertical rods 41 are placed in corresponding vertical positioning grooves 111, and the convex structures on the two transverse plates 42 at both ends of the pressing cover plate 4 are also inserted into corresponding transverse positioning grooves 112. Then, start each driving device 3 to drive the pressing block 2 close to the support seat 1, so as to fix the pressing cover plate 4 on the support seat 1 through the pressing block 2, thereby realizing rapid and accurate positioning of the pressing cover plate 4; since the positioning function of the positioning groove 11 will not fail after long-term use, the welding tooling for the pressing cover plate can also have a good positioning effect after long-term use, so that the welding effect of the pressing cover plate 4 will not be affected by inaccurate positioning, ensuring that the pressing cover plate 4 will not be unable to be used to press electrical components due to inaccurate positioning during the welding process.

[0036] The working principle of a welding tooling for press-fitting a cover plate during use of the present application is specifically as follows:

[0037] The user can first place the press-fitting cover plate 4 on the support plate 14 and adjust the position of the press-fitting cover plate 4 so that both vertical rods 41 are placed in corresponding vertical positioning grooves 111, and the convex structures on the two transverse plates 42 at both ends of the press-fitting cover plate 4 are also inserted into corresponding transverse positioning grooves 112. Then, start each driving device 3 to drive the pressing block 2 close to the support base 1, so as to be able to fix the press-fitting cover plate 4 on the support base 1 through the pressing block 2, thereby enabling rapid and accurate positioning of the press-fitting cover plate 4; since the positioning function of the positioning groove 11 will not fail after long-term use, the welding tooling for the press-fitting cover plate can also have a good positioning effect after long-term use, so that the welding effect of the press-fitting cover plate 4 will not be affected by inaccurate positioning, ensuring that the press-fitting cover plate 4 will not be unable to be used for press-fitting electrical components due to inaccurate positioning during welding processing.
