Description

Technical field:

[0002] The invention relates to the field of production and processing of multi-station seats, and mainly to a multi-station seat welding workstation. Background technology:

[0004] The car seat is composed of a seat plate and a back plate, which are mostly formed directly from plates and then assembled by welding. The existing technology often uses manual lap welding, which has many problems: 1. Low efficiency and low production capacity; 2. Unstable quality of welds, leaking welds, inaccurate welding dimensions, insufficient weld height and strength, etc.; 3. High labor intensity of workers. In addition, the existing production and processing are mostly production line flow operations. In order to ensure the normal operation of the production line and to improve welding efficiency, it usually takes six people to complete the welding of the seat back plate and the seat plate. The welding strength is high and the welding stability is poor, which affects the product quality. Summary of the invention:

[0006] The purpose of the present invention is to make up for the defects of the existing technology and provide a multi-station chair welding workstation to ensure the continuity of work. The work that originally required six people can be completed by one person, thereby improving work efficiency and saving labor costs.

[0007] The present invention is achieved through the following technical solutions:

[0008] 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said adjusting base has two limit switches, and said two limit switches are connected along said cam path to each other, and said two limit switches are connected along said cam path to each other, and said two limit switches are connected along said cam path to each other, and said two limit switches are connected along said cam path to each other, and said two limit switches are connected along said cam path to each other

[0009] A base plate 1 for clamping and positioning the side support plate is also provided on the bottom plate 1 of the outer seat plate mold of the clamp assembly. The outer side of the base plate 1 and the outer side of the clamp assembly are respectively installed with quick clamps for pressing the support plate in the concave cavity and the cardboard formed with the seat plate.

[0010] The support plate comprises two vertical plates arranged at intervals, and a horizontal plate is arranged on the vertical plates, and the specification of the horizontal plate matches the inner cavity of the seat plate.

[0011] The card plate assembly includes two card plates, one and two arranged in parallel. The card plate one is located on the inner side, and its upper end cooperates with the bottom ends of the bent edges on both sides of the seat plate. The card plate two is located on the outer side of the card plate one, and is provided with a card groove and an arc surface that cooperate with the support plate. The positions of the card plate one and the card plate two corresponding to the card grooves are provided with slots.

[0012] A flippable pressing plate is respectively arranged above the first and second clamping plates, and a clamping groove is arranged at the bottom end of the pressing plate, and the clamping groove is buckled with the upper end of the side support plate, and the flipping of the pressing plate is driven by a quick clamp.

[0013] A second clamping plate for clamping the side support plates on both sides of the seat plate is provided on the outer side of the back plate clamping position on the upper end surface of the back plate mold, and quick clamps are respectively installed on the two sides and rear end of the second clamping plate and the back plate clamping position.

[0014] The quick clamp includes a seat plate, on which mounting and fixing holes are distributed, a guide sleeve is provided at the front end of the seat plate, a support ear is provided at the rear end of the seat plate, a driving handle is hinged on the support ear, a connecting plate is installed at the front end of the driving handle, a guide rod that cooperates with the guide sleeve is installed at the front end of the connecting plate, and a fixing pin is installed at the end of the guide rod.

[0015] A storage box is installed on the bottom end surface of the rotating workbench corresponding to the workstations where the seat plate mold and the back plate mold are located.

[0016] The storage box is composed of a plurality of storage compartments arranged in parallel, and the storage box is arranged to be inclined downward.

[0017] The principle is: since the positioner is a special welding auxiliary equipment, it is suitable for welding position shifting in rotary work to obtain the ideal processing position and welding speed. It can be used in conjunction with the operator and welding machine to form an automatic welding center, and can also be used for workpiece position shifting during manual operation. The worktable rotation adopts variable frequency drive stepless speed regulation with high speed regulation accuracy. The remote control box can realize remote operation of the worktable, and can also be connected with the operator and welding machine control system to realize linkage operation. The welding positioner is generally composed of a worktable rotation mechanism and a flipping mechanism. Through the lifting, flipping and rotation of the worktable, the workpiece fixed on the worktable can reach the required welding and assembly angle. The worktable rotation is variable frequency stepless speed regulation, which can obtain a satisfactory welding speed.

[0018] The present application can be used to support the installation, rotation and flipping of the rotary workbench through the structure of positioner 1 and positioner 2 at both ends of the working base plate. The two workstations on the rotary workbench are designed to form four workstations. In conjunction with the rotation of the positioner, the four workstations are used to work together to ensure that the manipulator does not stop. Single-person single-station operation maximizes equipment utilization, which can not only ensure the original six-person operating capacity, but also ensure the stability of seat welding and its welding quality. The two workstations on the same rotary workbench are separated by a partition to avoid splashing during welding. The four workstations are grouped in twos. When one group is welding, the other can be assembled, thereby ensuring the continuity of work. The work that was originally completed by six people can be completed by one person, which improves work efficiency, saves labor costs, is convenient to operate, and has high product welding quality.

[0019] The advantages of the present invention are:

[0020] The present invention has a reasonable structural design. The four workstations are grouped in pairs. When one group is welding, the other can be assembled, thereby ensuring the continuity of work. The work that originally required six people to cooperate can be completed by one person, which improves work efficiency, saves labor costs, is convenient to operate, and has high product welding quality.

Specific implementation method:

[0032] See attached picture.

[0033] A multi-station seat welding workstation includes a station base 1, a positioner 2 and a positioner 3 are respectively mounted at both ends of the station base 1, a rotary worktable 4 is respectively installed on the positioner 2 and the positioner 3, two symmetrical stations are respectively arranged on the rotary worktable 4, and the stations are separated by a partition 5, and a seat plate mold 6 for clamping a seat plate and a side support plate is respectively installed on the two stations of the positioner 2, and the seat plate mold 6 includes a bottom plate 6-1, and a support plate for supporting a seat plate body is installed in the middle of the bottom plate 6-1. The support plate 6-2 has two symmetrically arranged clamping plate assemblies 6-3 installed on the outer side of the support plate 6-2 for clamping the side support plates on both sides of the positioning seat plate. The two stations of the positioner 2 3 are respectively installed with a back plate mold 7 for clamping and fixing the back plate. The back plate mold 7 includes a bottom plate 2 7-1. The bottom plate 2 7-1 is provided with a fixed ear bracket 7-2 for fixing one side of the backrest plate corresponding to the adjustment bracket. A welding robot 8 for welding the product on the station is installed in the middle of the station base 1. The rotation of the rotating workbench 4 is driven by the motor underneath it.

[0034] Furthermore, a base plate 1 is provided on the bottom plate 1 of the seat plate mold 6 outside the card assembly 6-3 for clamping and positioning the side support plate. The outside of the base plate 1 and the outside of the card assembly are respectively provided with a quick clamp 10 for clamping the support plate in the cavity and the paperboard formed with the seat plate. Since two side support plates are provided on both sides of the seat plate, the side support plates need to be welded with corresponding fixing parts before being assembled with the seat plate. The structure of the base plate 1 is used to clamp and fix the side support plates. The quick clamp facilitates the operation and improves the clamping and assembly efficiency.

[0035] Furthermore, the support plate 6-2 includes two vertical plates 11 arranged at intervals, and a horizontal plate 12 is arranged on the vertical plate 11, and the specification of the horizontal plate 12 matches the inner cavity of the seat plate. Through the cooperation between the vertical plate and the horizontal plate, the inner cavity of the seat plate is exactly matched, and when the seat plate is clamped, it can be directly buckled on the horizontal plate to achieve assembly and positioning.

[0036] Furthermore, the card assembly 6-3 includes two card plates 13 and 14 arranged in parallel. The card plate 13 is located on the inner side, and its upper end portion cooperates with the bottom ends of the bent edges on both sides of the seat plate. The card plate 2 14 is located on the outer side of the card plate 13, and is provided with a card groove 15 and an arc surface 16 that cooperate with the support plate. The position of the card plate 13 and the card plate 2 14 corresponding to the card groove 15 is provided with a slot 17; through the matching structure of the card plate 1 and the card plate 2, on the one hand, the top of the card plate 1 realizes the enhanced support and positioning of the seat plate body, and on the other hand, the card plate 2 can realize the card installation and positioning of the side support plate, and the positioning of the side support plate can be achieved by the quick clamp. A flippable pressing plate 18 is respectively mounted above the clamping plate 13 and the clamping plate 2 14, and a clamping groove is provided at the bottom end of the pressing plate 18, which is engaged with the upper end of the side support plate, and the flipping of the pressing plate 18 is driven by the quick clamp 10; because the side support plate is a separate structure from the seat plate before welding, and the side support plate is relatively small, in order to ensure the stability of the side support plate clamping and the gap on both sides of the seat plate, the upper end of the side support plate is pressed by the pressing plate, thereby ensuring the stability of the side support plate before welding and improving the quality of automatic welding of the robot.

[0037] Furthermore, a second clamping plate 19 for clamping the side support plates on both sides of the seat plate is provided on the outer side of the back plate clamping position on the upper end surface of the back plate mold 7, and quick clamps 10 are respectively installed on the two sides and rear ends of the second clamping plate 19 and the back plate clamping position. Due to the synchronous assembly of the four stations, when the seat plate is welded with the side support plates on both sides, one seat plate requires two side support plates, which will invert the welding station requirements of the side support plates, and two stations require four side support plates. There are two side support plate clamping concave cavities on the seat plate mold, so the second clamping plate is set at the redundant position on the back plate mold, which can reasonably utilize the space and is also conducive to the welding operation of the welding manipulator.

[0038] Further, the quick clamp 10 includes a seat plate 10-1, on which mounting holes are distributed, a guide sleeve 10-2 is provided at the front end of the seat plate 10-1, a support ear 10-3 is provided at the rear end of the seat plate 10-1, a driving handle 10-4 is hinged on the support ear 10-3, a connecting plate 10-5 is installed at the front end of the driving handle 10-4, a guide rod 10-6 that cooperates with the guide sleeve is installed at the front end of the connecting plate 10-5, and a fixing pin is installed at the end of the guide rod 10-6. By welding corresponding fixing pins for connecting corresponding holes on the basis of the existing quick clamp structure, quick insertion and positioning can be achieved.

[0039] Furthermore, a storage box 20 is installed on the bottom end surface of the rotating workbench 4 corresponding to the workstations where the seat plate mold 6 and the back plate mold 7 are located. Through the structure of the storage box, the parts to be assembled can be stored conveniently and taken out conveniently; the storage box 20 is composed of a plurality of storage compartments arranged in parallel, and the storage box is tilted downward. Through the structure of the storage box tilted downward, its tilted setting facilitates manual operation.
