DETAILED DESCRIPTION

[0033] The specific embodiments of the utility model will be described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0034] Please refer to the drawings Figure 1 to the drawings Figure 2 It is shown that the embodiment provides a kind of auxiliary tool 10 of seat cushion framework assembly, including rack 100, left side plate clamping unit, right side plate clamping unit, front cross bar clamping unit 300, rear cross bar clamping unit 200, lower mounting rod clamping unit and control panel.

[0035] In the embodiment, left side plate clamping unit, front cross bar clamping unit 300, lower mounting rod clamping unit, right side plate clamping unit and rear cross bar clamping unit 200 are sequentially installed on rack 100 along the length direction of rack 100, by so setting each clamping unit, according to the assembly order of each component unit on automobile seat cushion framework when assembling, so that worker is not easy to place each component unit or take each component unit after welding and take each component unit.

[0036] Control panel is respectively connected with left side plate clamping unit, right side plate clamping unit, front cross bar clamping unit 300, rear cross bar clamping unit 200 and lower mounting rod clamping unit control, for controlling each clamping unit to carry out clamping or loosening action.

[0037] By setting multiple auxiliary toolings for welding and clamping each component unit constituting the seat cushion framework on the same rack 100, all component units of the seat cushion framework can be completed on the same rack 100 during assembly, so that a reserved space for workers to stand and move between the periphery of the two adjacent auxiliary toolings is not needed, which solves the problem of occupying a large amount of factory space caused by positioning and assembling with multiple welding fixtures. Since the component units constituting the seat cushion framework are completed in the same batch on the same rack 100, the component units constituting the seat cushion framework are taken in the same batch, which solves the problem that workers are prone to take the wrong components during the process of taking the multiple components constituting the complete automobile seat framework.

[0038] Referring to the accompanying drawings Figure 1 to the accompanying drawings Figure 5 In the present embodiment, the rear cross rod clamping unit 200 includes a rear cross rod middle support tooling 230, a first rear cross rod end support tooling 210, a second rear cross rod end support tooling 220, and a pair of rear cross rod side clamping support toolings. The first rear cross rod end support tooling 210 and the second rear cross rod end support tooling 220 are symmetrically arranged at the left and right ends of the rack 100. The first rear cross rod end support tooling 210 and the second rear cross rod end support tooling 220 are used to clamp the opposite ends of the rear cross rod 20, i.e., the opposite ends of the rear cross rod 20 are axially supported and clamped by the first rear cross rod end support tooling 210 and the second rear cross rod end support tooling 220.

[0039] At the same time, since the rear cross rod 20 is an axle type part, which is usually long in axial length, in order to prevent the middle part of the rear cross rod 20 from deforming during welding and clamping, the rear cross rod middle support tooling 230 is installed on the rack 100 at the position corresponding to the middle part of the rear cross rod 20 when it is placed, i.e., the rear cross rod middle support tooling 230 is arranged between the first rear cross rod end support tooling 210 and the second rear cross rod end support tooling 220. The rear cross rod middle support tooling 230 is used to clamp the middle part of the rear cross rod. A pair of rear cross rod side clamping support toolings are respectively arranged adjacent to the inner sides of the first rear cross rod end support tooling 210 and the second rear cross rod end support tooling 220, and are used to position and clamp other connecting members at the opposite ends of the rear cross rod at the two ends of the rear cross rod. It can be understood that different models of automobile seat cushion frameworks differ, and the connecting members configured at the two ends of the rear cross rod also differ in shape, which results in different shapes of the connecting members. Therefore, the corresponding welding and clamping tooling can be selected according to the specific shape of the connecting member.

[0040] Referring to the accompanying drawings Figure 2 and the accompanying drawings Figure 3As shown, specifically, the first rear cross bar end portion supporting tool 210 comprises a first rear cross bar supporting cylinder 2101, a push rod 2102 and a first V-shaped supporting block 2103. The first rear cross bar supporting cylinder 2101 is fixed on one side of the rack 100. The piston rod of the first rear cross bar supporting cylinder 2101 is connected with the push rod 2102, for driving the push rod 2102 to move close to or away from one side of the second rear cross bar end portion supporting tool 220. The first V-shaped supporting block 2103 is arranged close to the inner side of the first rear cross bar supporting cylinder 2101. The first V-shaped supporting block 2103 is used for supporting and limiting one end of the rear cross bar, for preventing the rear cross bar from shaking left and right.

[0041] Referring to the accompanying drawings Figure 2 and the accompanying drawings Figure 4 As shown, specifically, the second rear cross bar end portion supporting tool 220 comprises a second rear cross bar supporting cylinder, a turnover arm 2201 and a supporting block 2202. The second rear cross bar supporting cylinder is fixedly installed on the other side of the rack 100. One end of the turnover arm 2201 is connected with the piston rod of the second rear cross bar supporting cylinder. The other end of the turnover arm 2201 is connected with the supporting block 2202. The supporting block 2202 cooperates with the push rod 2102, for clamping the opposite two ends of the rear cross bar.

[0042] When the operator clamps and installs the rear cross bar, the second rear cross bar supporting cylinder acts, drives the turnover wall to turn upward, so that the supporting block 2202 moves to the position of the opposite other end of the push rod. At this time, the operator places one end of the rear cross bar against the inner side surface of the supporting block 2202, and places the other end of the rear cross bar on the first V-shaped supporting block 2103. After the rear cross bar is placed in position, the first rear cross bar supporting cylinder 2101 acts, drives the push rod to move to one side of the second rear cross bar end portion supporting tool 220, applies an axial force to the rear cross bar, so as to axially compress the rear cross bar between the first rear cross bar end portion supporting tool 210 and the second rear cross bar end portion supporting tool 220.

[0043] Referring to the accompanying drawings Figure 2 and the accompanying drawings Figure 4 As shown, specifically, the rear cross bar middle portion supporting tool 230 comprises a rear cross bar middle portion supporting cylinder 2301, a rear cross bar middle portion pressing arm 2302, a rear cross bar middle portion fixing seat 2304 and a rear cross bar middle portion pressing block 2303. The rear cross bar middle portion supporting cylinder 2301 is fixedly installed on the rack 100. The rear cross bar middle portion fixing seat 2304 is fixedly installed on the upper end surface of the rack 100. One end of the rear cross bar middle portion pressing arm 2302 is connected with the piston rod of the rear cross bar middle portion supporting cylinder 2301. The rear cross bar middle portion pressing block 2303 is fixedly installed on the other end bottom end of the rear cross bar middle portion pressing arm 2302. The rear cross bar middle portion pressing block 2303 is used for applying downward pressure to the middle portion of the rear cross bar. The rear cross bar middle portion pressing arm 2302 is hingedly installed on the rear cross bar middle portion fixing seat 2304.

[0044] After the rear crossbar is axially clamped by the first rear crossbar end support fixture 210 and the second rear crossbar end support fixture 220, the rear crossbar intermediate support cylinder 2301 is activated, causing the rear crossbar intermediate pressure arm 2302 to flip downward. The rear crossbar intermediate pressure arm 2302 drives the rear crossbar intermediate pressure block 2303 to press down and press against the upper part of the rear crossbar, applying a downward force to the rear crossbar. At the same time, a support seat is correspondingly provided below the middle position of the rear crossbar, pressing and fixing the middle part of the rear crossbar onto the support seat to prevent the middle part of the rear crossbar from moving during subsequent welding operations.

[0045] See attached document Figure 1 and attached Figure 2 As shown, the front crossbar clamping unit 300 includes a first front crossbar end support fixture 310, a second front crossbar end support fixture 320, and a front crossbar middle clamping fixture 330. The first front crossbar end support fixture 310 and the second front crossbar end support fixture 320 are arranged opposite each other on the left and right sides of the frame 100. The front crossbar middle clamping fixture 330 is arranged between the first front crossbar end support fixture 310 and the second front crossbar end support fixture 320. The front crossbar middle clamping fixture 330 is used to apply a downward force to the middle part of the front crossbar.

[0046] By adopting the aforementioned front crossbar clamping unit 300 structure, the front crossbar 30 can be quickly installed and clamped for positioning. Furthermore, during the subsequent welding process, the front crossbar 30 is less likely to shift, which helps ensure welding quality.

[0047] It should be noted that the front crossbar 30 is shorter in axial length than the rear crossbar 20, meaning that the middle section of the front crossbar 30 is less prone to deformation during welding, and therefore does not require a support device for the middle section. However, a connecting piece is provided at the bottom of the middle section of the front crossbar 30 (see attached diagram). Figure 7 As shown, the connecting piece needs to be welded to the bottom of the middle position of the front crossbar 30. Therefore, during the welding process, a downward force needs to be applied to the middle position of the front crossbar 30 to ensure that the bottom of the front crossbar contacts the connecting piece below.

[0048] See attached document Figure 7As shown, specifically, the front crossbar middle pressing tool 330 includes a front crossbar middle cylinder 3301, a front crossbar middle pressing arm 3302, a front crossbar middle fixed seat 3304, and a front crossbar middle pressing block 3303. The front crossbar middle cylinder 3301 is fixedly installed on the rack 100. One end of the front crossbar middle pressing arm 3302 is fixedly connected with a piston rod of the front crossbar middle cylinder 3301. The front crossbar middle pressing block 3303 is fixedly installed on the other end of the front crossbar middle pressing arm 3302. The front crossbar middle pressing block 3303 is used to apply downward pressure to the middle part of the front crossbar. The front crossbar middle pressing arm 3302 is hingedly installed on the front crossbar middle fixed seat 3304.

[0049] After the front crossbar is axially pressed by the first front crossbar end support tool 310 and the second front crossbar end support tool 320, the front crossbar middle cylinder 3301 acts to drive the front crossbar middle pressing arm 3302 to overturn relative to the front crossbar middle fixed seat 3304, so that the front crossbar middle pressing block 3303 presses and tightens the upper end face at the middle position of the front crossbar, and applies downward force to the middle position of the front crossbar, so that the bottom end of the middle position of the front crossbar is attached to the connecting piece below.

[0050] Referring to Figs. 1 and 2, Figure 2 and Figs. 3 and 4, Figure 6 As shown, the first front crossbar end support tool 310 includes a front crossbar cylinder 3101, a front crossbar push rod 3103, and a first front crossbar V-shaped support seat 3102. The front crossbar cylinder 3101 is fixedly installed on one side of the rack 100. One end of the front crossbar push rod 3103 is fixedly connected with a piston rod of the front crossbar cylinder 3101. The front crossbar cylinder 3101 is used to drive the front crossbar push rod 3103 to move close to or away from the second front crossbar end support tool 320. The first front crossbar V-shaped support seat 3102 is arranged adjacent to the inner side of the front crossbar cylinder 3101.

[0051] Referring to Figs. 1 and 2, Figure 2 and Figs. 3 and 4, Figure 8 As shown, the second front crossbar end support tool 320 includes a front crossbar fixed seat 3201 and a second front crossbar V-shaped support seat 3202. The front crossbar fixed seat 3201 is fixedly installed on the other side of the rack 100 relative to the front crossbar cylinder 3101. The second front crossbar V-shaped support seat 3202 is arranged adjacent to the inner side of the front crossbar fixed seat 3201.

[0052] When the operator clamps the front cross bar for welding, the operator first places the opposite ends of the front cross bar horizontally on the first front cross bar V-shaped support seat 3102 and the second front cross bar V-shaped support seat 3202, and can place one end of the front cross bar against the inner end face of the front cross bar fixing seat 3201, then starts the front cross bar cylinder 3101, so that the front cross bar cylinder 3101 drives the front cross bar push rod 3103 to move to one side of the front cross bar fixing seat 3201, so that the front cross bar push rod 3103 exerts an axial force on the front cross bar, and the front cross bar is axially pressed and fixed between the first front cross bar end support tool 310 and the second front cross bar end support tool 320. Finally, the front cross bar middle cylinder 3301 acts, driving the front cross bar middle pressing arm 3302 to flip relative to the front cross bar middle fixing seat 3304, so that the front cross bar middle pressing block 3303 presses and tightens the upper end face at the middle position of the front cross bar, and exerts a downward force on the middle position of the front cross bar, so that the bottom end of the middle position of the front cross bar is attached to the lower connecting piece.

[0053] Finally, it should be pointed out that in the present embodiment, since the front cross bar and the lower mounting rod have substantially the same shape, the clamping and fixing tool for them is also the same as the clamping and fixing tool for the front cross bar, and therefore the clamping unit for the lower mounting rod will not be described here, i.e. the clamping unit for the lower mounting rod can directly use the structure design of the clamping unit for the front cross bar; at the same time, since the left side plate clamping unit and the right side plate clamping unit are used to clamp the left side plate and the right side plate of the automobile seat cushion framework, the left side plate and the right side plate are plate-shaped members, and the plate-shaped members corresponding to different automobile models are different, and the clamping tool for the left side plate and the right side plate on the automobile seat cushion framework already exists in the prior art, and therefore it will not be described repeatedly in the present embodiment.

[0054] In addition, since the front cross bar clamping unit and the rear cross bar clamping unit 200 in the present embodiment both use a cylinder as a power source, the control device can directly use the existing cylinder gas source control structure, and therefore will not be described here.
