Description

Technical Field

[0001] This utility model relates to the field of car audio manufacturing, specifically a gas pipe shell fixing clamp positioning and pressing device. Background Technology

[0002] The gas pipe housing is a crucial component of car audio systems. For certain models, its installation requires a specially shaped clamp structure, comprising an upper conical portion, a middle circular portion, and a lower square portion. Currently, the clamp is typically manually inserted into a slot on one side of the gas pipe housing's flange. However, this method is inefficient and prone to incorrect installation. Ideally, the circular portion should be on the upper side of the flange slot, and the square portion on the lower side. However, workers are often unaware of subsequent procedures, leading to a situation where the circular portion is below the flange slot and the square portion is above. This discrepancy is difficult to detect until the final assembly, at which point the gas pipe housing must be reworked, impacting production schedules. Utility Model Content

[0003] The purpose of this utility model is to provide a gas pipeline shell fixing clamp positioning and pressing device, which can avoid the fixing clamp being installed backwards and can realize the automatic pressing of the fixing clamp.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A gas pipeline shell fixing clamp positioning and pressing device includes a mounting plate and a pressing mechanism disposed on the mounting plate. The mounting plate is provided with a positioning component for positioning the gas pipeline shell, and the pressing mechanism is disposed on one side of the positioning component. The pressing mechanism includes a pressing cylinder, a guide seat, and a pressing positioning seat. The guide seat is provided with a guide groove, and the fixing clamp is disposed in the guide groove. A push rod is provided at the front end of the pressing cylinder and inserted into the guide groove. The fixing clamp is driven to move by the push rod. A first wing plate of the gas pipeline shell to be installed is disposed on the pressing positioning seat, and a wing plate slot for the fixing clamp to be inserted is provided on one side of the first wing plate. The wing plate slot is correspondingly connected to the guide groove. The fixing clamp includes a conical part, a disc part, and a square disc part arranged sequentially from top to bottom. The guide groove has a guide inclined surface and a first limiting groove on both sides of the groove wall. The lower side of the disc part contacts the guide inclined surface, and the square disc part is disposed in the first limiting groove.

[0006] The guide groove has a first limiting protrusion, a second limiting protrusion, and a second limiting groove arranged sequentially from top to bottom on both sides of the groove wall. The first limiting groove is formed between the first limiting protrusion and the second limiting protrusion. The push rod has an upper guide protrusion and a lower guide protrusion on both sides. When the push rod moves, the upper guide protrusion slides along the upper surface of the corresponding first limiting protrusion, and the lower guide protrusion moves along the corresponding second limiting groove.

[0007] The push rod has an upper pushing part and a lower pushing part at its front end, and a receiving recess is formed between the upper pushing part and the lower pushing part. When it is fixed and clamped, the upper pushing part contacts the tapered part, the lower pushing part contacts the square disk part, and the disk part is placed in the receiving recess.

[0008] The pressing mechanism is mounted on a bracket, and one end of the bracket is provided with a hinge seat and a rotating receiving recess for the cylinder body of the pressing cylinder to rotate into. The front end of the cylinder body of the pressing cylinder is mounted on the hinge seat. The front end of the cylinder rod of the pressing cylinder is provided with a connecting seat, and the rear end of the push rod is provided with a connecting block. The connecting block is fixedly connected to the connecting seat by bolts.

[0009] The press-fit positioning seat has a positioning platform in the middle and a transition surface on the side of the press-fit positioning seat near the guide seat. The height of the first limiting groove and the height of the positioning platform are both higher than the transition surface.

[0010] The pressing mechanism includes a positioning and pressing device and a positioning column. The first wing plate is provided with a wing plate through hole, and the lower end of the positioning column passes through the wing plate through hole and contacts the pressing and positioning seat. The upper end of the positioning column is pressed and fixed by the positioning and pressing device.

[0011] The positioning components on the mounting plate include an end positioning block A, a height positioning block, an outer positioning block, an end positioning block B, an inner positioning block, and a second wing plate positioning seat. The end positioning block A and the end positioning block B are respectively located at both ends of the mounting plate, the outer positioning block is located on one side of the mounting plate, and the inner positioning block and the second wing plate positioning seat are both located in the middle of the mounting plate and on one side of the pressing mechanism. One end of the gas pipe shell is positioned by the end positioning block A, and the other end is positioned by the end positioning block B. One side of the gas pipe shell has a protrusion, and the other side has a straight edge. The protrusion is positioned by the outer positioning block, and the straight edge is positioned by the inner positioning block. The gas pipe shell has a second wing plate at the end away from the first wing plate, and the second wing plate is positioned by the second wing plate positioning seat. The lower surface of the gas pipe shell is supported and positioned by the various height positioning blocks.

[0012] The end positioning block A, the outer positioning block, the end positioning block B, and the inner positioning block are all provided with positioning grooves that match the shape of the gas pipe shell. The straight edge of the gas pipe shell is provided with multiple protrusions, and each protrusion is embedded in the corresponding positioning groove on the inner positioning block.

[0013] The gas pipeline shell has a connecting protrusion at the middle of its outer edge, and the connecting protrusion is supported by the upper surface of the end positioning block A, the upper surface of the outer positioning block, the upper surface of the end positioning block B, and the upper surface of the inner positioning block. The height positioning block has a fine-adjustment bolt in the middle.

[0014] The mounting plate is equipped with a control box, and the control box has a flip-open cover. The mounting plate has a handle on its edge, and each corner of the mounting plate has a support foot.

[0015] The advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model utilizes the guide groove structure on the guide seat in the press-fitting mechanism to limit the insertion of the fixing clamp to a position where the conical part faces upward, thereby avoiding the fixing clamp being installed backwards. Then, the push rod in the press-fitting mechanism automatically completes the pressing of the fixing clamp, improving production efficiency and installation quality.

[0017] 2. This utility model positions the main body of the gas pipeline shell using the positioning components on the mounting plate. The first wing plate of the gas pipeline shell to be installed is placed on the pressing positioning seat in the pressing mechanism and further limited by the positioning column, thereby ensuring that the first wing plate will not move during the pressing of the fixing clamp, thus ensuring the installation quality of the fixing clamp.

[0018] 3. The push rod of this utility model can be replaced as needed, and when the push rod is separated from the pressing cylinder, the front end of the pressing cylinder can be rotated upward to leave enough space for the push rod to retract and separate from the guide seat. This can shorten the overall length of the bracket used to support the pressing cylinder, guide seat and other components, thereby facilitating the integration of the pressing mechanism, control box and other components onto the mounting plate.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] like Figures 1-13 As shown, this utility model includes an installation plate 1 and a pressing mechanism 3 disposed on the installation plate 1. The installation plate 1 is provided with a positioning component for positioning a gas pipeline shell 4, and the pressing mechanism 3 is disposed on one side of the positioning component. The pressing mechanism 3 includes a pressing cylinder 301, a guide seat 304, and a pressing positioning seat 305 arranged in a straight line in sequence. The guide seat 304 is provided with a guide groove, and a fixing clamp 5 is disposed in the guide groove. The front end of the pressing cylinder 301 is provided with a push rod 303 that is inserted into the guide groove, and the fixing clamp 5 is driven to move by the push rod 303. The first wing plate 401 of the gas pipeline shell 4 to be installed is disposed on the pressing positioning seat 305, and as shown... Figure 6 As shown, the first wing plate 401 has a wing plate slot 4011 on one side for the insertion of the fixing clip 5, as shown. Figure 5 As shown, the wing plate slot 4011 is correspondingly connected to the guide groove, as... Figure 8 As shown, the fixing clip 5 includes a tapered portion 501, a disc portion 502, and a square disc portion 503 arranged sequentially from top to bottom, and as... Figure 10As shown, the guide groove has guide slopes 3044 and first limiting grooves 3043 on both sides of the groove wall. The lower side of the disc portion 502 of the fixing clip 5 contacts the guide slope 3044, and the square disc portion 503 of the fixing clip 5 is disposed in the first limiting groove 3043. When the present invention is working, the guide groove structure limits the fixing clip 5 to be inserted only with the conical portion 501 facing upward, thereby avoiding the fixing clip 5 being installed backward. Then, the pressing cylinder 301 is activated and the push rod 303 presses the fixing clip 5 in the guide groove into the wing plate slot 4011 on the first wing plate 401.

[0035] like Figures 9-10 As shown, in this embodiment, the guide groove has a first limiting protrusion 3042, a second limiting protrusion 3041, and a second limiting groove 3045 arranged sequentially from top to bottom on both sides of the groove wall. The first limiting protrusion 3042 and the second limiting protrusion 3041 form the first limiting groove 3043. The push rod 303 has an upper guide protrusion 3034 and a lower guide protrusion 3035 on both sides. When the push rod 303 moves, the upper guide protrusion 3034 slides along the upper surface of the corresponding side first limiting protrusion 3042, and the lower guide protrusion 3035 moves along the corresponding side second limiting groove 3045, thereby ensuring that the push rod 303 moves linearly to complete the accurate pressing of the fixing clamp 5.

[0036] like Figures 9-10 As shown, in this embodiment, the front end of the push rod 303 is provided with an upper pushing part 3032 and a lower pushing part 3033, and an accommodating recess is formed between the upper pushing part 3032 and the lower pushing part 3033. When the fixing clamp 5 is pressed in, the upper pushing part 3032 contacts the conical part 501 of the fixing clamp 5, the lower pushing part 3033 contacts the square disc part 503 of the fixing clamp 5, and the disc part 502 of the fixing clamp 5 is placed in the accommodating recess.

[0037] like Figure 1 , Figure 5 and Figures 12-13 As shown, in this embodiment, the pressing mechanism 3 is mounted on a bracket 6. One end of the bracket 6 is provided with a hinge seat 309 and a rotating receiving recess 601 for the cylinder body of the pressing cylinder 301 to rotate into. The front end of the cylinder body of the pressing cylinder 301 is mounted on the hinge seat 309. The front end of the cylinder rod of the pressing cylinder 301 is provided with a connecting seat 302. The rear end of the push rod 303 is provided with a connecting block 3031, which is fixedly connected to the connecting seat 302 by bolts. This structure facilitates the installation and replacement of the push rod 303, and also reduces the length of the bracket 6, thereby facilitating the overall transfer of the pressing mechanism 3 and its integration onto the mounting plate 1. When the push rod 303 is replaced, such as... Figures 12-13As shown, the operator first disassembles the connecting block 3031 at the rear end of the push rod 303 from the connecting seat 302, then rotates the front end of the pressing cylinder 301 upward to leave enough space for the push rod 303 to retract and separate from the guide seat 304. At this time, the cylinder body of the pressing cylinder 301 can rotate into the rotating receiving recess 601. Then, the operator removes the original push rod 303 and sends the new push rod 303 into the lower side of the front end of the pressing cylinder 301. Then, the operator inserts the new push rod 303 into the guide seat 304. Finally, the front end of the pressing cylinder 301 is restored to horizontal, and the connecting block 3031 at the rear end of the new push rod 303 is fixed to the connecting seat 302 to complete the replacement. The push rods 303 of different specifications have the same length. The main difference is that the upper push part 3032, the lower push part 3033, the receiving notch and other structures at the front end need to be matched with the fixing clamps of different specifications in five directions. The connecting seat 302 can also be equipped with a pressure sensor as needed to detect in real time whether the pressing force of the push rod 303 meets the requirements. The pressure sensor is a technology known in the art and is a commercially available product.

[0038] like Figure 9 and Figure 11 As shown, in this embodiment, the press-fit positioning seat 305 has a positioning platform 3052 in the middle, and a transition surface 3051 is provided on the side of the press-fit positioning seat 305 near the guide seat 304. The height of the first limiting groove 3043 and the height of the positioning platform 3052 are both higher than the transition surface 3051. The first limiting groove 3043 is higher than the transition surface 3051, so the fixing clip 5 can be inserted from the end of the guide seat 304 away from the press-fit cylinder 301. The first wing plate 401 is provided on the positioning platform 3052, and the height of the positioning platform 3052 is higher than the transition surface 3051. This way, when the fixing clip 5 moves along the wing plate slot 4011, the lower end will not contact the transition surface 3051, thereby avoiding frictional obstruction. In addition, the height of the positioning platform 3052 must ensure that the fixing clip 5 can accurately enter the wing plate slot 4011.

[0039] like Figure 1 , Figure 5 , Figure 6 and Figure 11 As shown, in this embodiment, the pressing mechanism 3 includes a positioning and pressing device 306 and a positioning post 307. The first wing plate 401 is provided with a wing plate through hole 4012, and the lower end of the positioning post 307 passes through the wing plate through hole 4012 and contacts the positioning table 3052. The upper end of the positioning post 307 is pressed and fixed by the positioning and pressing device 306. When this utility model is used, as... Figure 2As shown, the main body of the gas pipeline shell 4 is positioned by the positioning component on the mounting plate 1, while the first wing plate 401 to be installed is further positioned by the positioning post 307, thereby ensuring that the first wing plate 401 will not move when the fixing clamp 5 is pressed in.

[0040] like Figure 5 As shown, in this embodiment, the positioning and pressing device 306 includes a lifting cylinder, a pressing block 3061 and a pressing head 3062, wherein the pressing block 3061 is driven to lift and lower by the lifting cylinder, the pressing head 3062 is located at the front end of the pressing block 3061, and the upper end of the positioning column 307 is pressed by the pressing head 3062.

[0041] like Figure 5 and Figure 11 As shown, in this embodiment, the pressing positioning seat 305 is provided with a marking device 308 on the side away from the guide seat 304 for marking the first wing plate 401 after installation. The marking device 308 is a technology known in the art and is a commercially available product.

[0042] like Figures 1-4 As shown, in this embodiment, the positioning components on the mounting plate 1 include an end positioning block A101, a height positioning block 102, an outer positioning block 103, an end positioning block B104, an inner positioning block 105, and a second wing plate positioning seat 108. The end positioning blocks A101 and B104 are respectively located at both ends of the mounting plate 1, the outer positioning block 103 is located on one side of the mounting plate 1, and the inner positioning block 105 and the second wing plate positioning seat 108 are both located in the middle of the mounting plate 1 and on one side of the pressing mechanism 3. (Gas pipe) One end of the gas pipe shell 4 is positioned by an end positioning block A101, and the other end is positioned by an end positioning block B104. One side of the gas pipe shell 4 has a protrusion, and the other side has a straight edge. The protrusion is positioned by an outer positioning block 103, and the straight edge is positioned by an inner positioning block 105. The gas pipe shell 4 has a second wing plate 402 at the end away from the first wing plate 401, and the second wing plate 402 is positioned by a second wing plate positioning seat 108. The lower surface of the gas pipe shell 4 is supported and positioned by various height positioning blocks 102.

[0043] like Figures 1-2 As shown in this embodiment, the end positioning block A101, the outer positioning block 103, the end positioning block B104 and the inner positioning block 105 are all provided with positioning grooves that match the shape of the gas pipe shell 4. The straight edge of the gas pipe shell 4 is provided with multiple protrusions, and each protrusion is embedded in the corresponding positioning groove on the inner positioning block 105 to achieve positioning.

[0044] like Figures 1-4As shown, in this embodiment, the gas pipe shell 4 is assembled from two upper and lower half-shells. Thus, a connecting protrusion 403 is formed at the junction of the middle of the outer edge of the gas pipe shell 4. The connecting protrusion 403 is supported and its height is limited by the upper surfaces of the end positioning block A101, the outer positioning block 103, the end positioning block B104, and the inner positioning block 105. Simultaneously, each height positioning block 102 supports the lower surface of the gas pipe shell 4 to prevent it from being suspended in mid-air. Figure 1 As shown, the height positioning block 102 is provided with a fine-tuning bolt 1021 in the middle. Tightening the fine-tuning bolt 1021 can change its height to ensure support for the gas pipeline shell 4 and avoid the situation where the height positioning block 102 is suspended in the air.

[0045] like Figure 1 As shown, in this embodiment, the second wing plate positioning seat 108 is provided with a mounting plate 1081, and as... Figure 2 As shown, the second wing plate 402 of the gas pipeline shell 4 is fixed to the mounting support plate 1081 by a positioning pin or bolt.

[0046] This invention ensures the positioning of the main body of the gas pipeline shell 4 through the positioning component, thereby preventing the main body of the gas pipeline shell 4 from shifting during the pressing of the fixing clamp 4.

[0047] like Figure 1 As shown, in this embodiment, the mounting plate 1 is provided with a control box 2, and the control box 2 is provided with a control module. The front panel of the control box 2 is provided with a control indicator element 203, which is a well-known technology in the art. The control indicator element 203 can be made of suitable components, such as control knobs, indicator lights, displays, etc. In addition, the upper side of the control box 2 is provided with a flip-open cover 201 to facilitate maintenance and wiring connection. The rear side of the cover 201 is hinged to the control box 2 by a hinge 202.

[0048] like Figure 1 As shown, in this embodiment, the mounting plate 1 is provided with a handle 106 to facilitate the operator to hold and transfer it, and each corner of the lower side of the mounting plate 1 is provided with a support foot 107.

[0049] The working principle of this utility model is as follows:

[0050] The present invention includes the following steps in operation:

[0051] Step 1: Insert the fixing clamp 5 into the guide groove from the side of the guide seat 304 away from the pressing cylinder 301. At this time, as follows... Figure 10As shown, the lower side of the disc portion 502 of the fixing clip 5 contacts the guide slope 3044, and the square disc portion 503 of the fixing clip 5 is disposed in the first limiting groove 3043, so the fixing clip 5 will not be installed backwards.

[0052] Step 2: Place the gas pipe housing 4 onto the mounting plate 1, where... Figure 2 As shown, the main body of the gas pipeline shell 4 is positioned by the positioning component on the mounting plate 1, and the first wing plate 401 of the gas pipeline shell 4 to be installed is placed on the pressing positioning seat 305 in the pressing mechanism 3.

[0053] Step 3: Insert the positioning pin 307 in the pressing mechanism 3 into the wing plate through hole 4012 on the first wing plate 401, and then activate the positioning and pressing device 306 to press and fix the positioning pin 307, thereby ensuring that the first wing plate 401 will not move when the fixing clamp 5 is pressed.

[0054] Step 4: The press-fit cylinder 301 is activated to drive the push rod 303 to move forward, thereby pressing the fixing clip 5 in the guide groove on the guide seat 304 into the wing plate slot 4011 on one side of the first wing plate 401.

[0055] Other examples Figures 12-13 As shown, before step one above, the present invention can also replace the appropriate push rod 303 as needed. The push rods 303 of different specifications have the same length. The main difference is that the upper pushing part 3032, the lower pushing part 3033, the receiving notch and other structures at the front end need to be matched with the fixing clamps of different specifications.
