Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of coating hangers, and in particular relates to a bumper on-vehicle electrophoresis tooling hanger and a use method thereof. Background Art
[0002] The car bumper is a safety device installed at the front and rear ends of the car to absorb and mitigate external impact and protect the front and rear parts of the car body. It not only has a decorative function, but more importantly, it has a safety protection function. The design of the three-section bumper has significant advantages in harsh working environments. In the event of a scratch, it does not need to be replaced as a whole, only the scratched section needs to be replaced. The three-section bumper is used on many truck models. When the three-section bumper is subjected to primer coating, the three sections of the bumper have different shapes, and the production efficiency is different when they are mounted on conventional primer hangers for separate electrophoresis. The shape of the middle section of the bumper is relatively straight, so a large number of parts can be mounted on a primer hanger, and the coating efficiency is relatively high; the left and right sections of the bumper have a large curvature, so the number of parts that can be mounted on the primer hanger at one time is small. In order to ensure the firmness of the mounting, the left and right sections of the bumper are tied and fixed on the primer hanger with wire, which results in a long time for mounting and disassembly before electrophoresis, which seriously wastes labor costs and is easy to scratch workers; electrophoresis of the left and right sections of the bumper will occupy production hanging points, making the coating efficiency low. Taking the Jiefang J7 as an example, the V3 car door electrophoresis hanger is currently used to mount the left and right sections of the bumper corresponding to the J7 bumper when the left and right sections are painted. Workers use wire to tie the bumper, and the hangers are loaded with a total of 8 parts. According to the timing, two workers working simultaneously need 25 minutes to complete the installation and hanging. After the electrophoresis is completed, it takes two people 20 minutes to dismantle all of them. Based on the daily production of 80 J7s, it takes two people 250 minutes to install and 200 minutes to dismantle. There is a serious waste of man-hours, and 10 production hanging points are occupied, affecting the electrophoresis capacity of the cab pre-treatment. Summary of the invention
[0003] The purpose of the present invention is to provide a bumper on-board electrophoresis tooling hanger and a method for using the same. The left section / right section of the bumper can be fixedly connected to the cab through a hook tooling and a bolt tooling of the on-board electrophoresis tooling, so that the left and right sections of the bumper are completely fitted on the front wall of the cab, and other parts do not interfere with the cab and deform, thereby ensuring the quality and firmness of the on-board electrophoresis. The on-board electrophoresis tooling has a simple structure, low cost, and is easy to load and unload. The hook tooling and the bolt tooling can be used in conjunction with an electric wrench, which greatly shortens the time for mounting and disassembling the bumper and saves labor costs. The on-board electrophoresis of the left and right sections of the bumper releases the pre-treatment electrophoresis hanging points occupied during separate electrophoresis, thereby improving the production capacity of the pre-treatment electrophoresis in the cab and reducing energy costs.
[0004] The specific contents of the plan are as follows:
[0005] A bumper on-vehicle electrophoresis tooling hanger includes a bumper on-vehicle fixing tooling, the bumper on-vehicle fixing tooling includes a bolt tooling and a hook tooling, the bolt tooling is adjacent to the top of the hook tooling, the hook tooling includes a hook movable connecting part and a bolt connecting part, and the bottom of the hook movable connecting part is limitedly slidably sleeved on the front of the bolt connecting part.
[0006] This bumper electrophoresis tooling hanger is used for the left and right sections of the three-section truck bumper to be mounted on the front wall of the truck cab respectively. Two sets of bolt tooling and hook tooling are used to fix the left and right sections of the bumper horizontally on the corresponding positions on the front face of the cab front wall panel using two-point fixing. The left and right sections of the bumper are both curved surfaces. The gap between the bumper and the cab is mainly guaranteed by the bumper shape. There is no surface contact. When the left and right sections of the bumper are mounted on the cab, there will be no fit and shielding between the bumper and the cab to affect the electrophoresis effect. The first bolt head of the bolt tooling is welded to the top of the first optical axis, and the first limit plate is sleeved on the first optical axis and welded and fixed to the rear end face of the first bolt head. The outer diameter of the first limit plate is slightly larger than the bumper mounting hole to ensure that the bumper can be clamped and the outer surface of the bumper is not blocked as much as possible to avoid affecting the electrophoresis effect. The length between the rear end face of the first limit plate and the rear end face of the first optical axis depends on the distance between the threaded hole of the cab front panel at the first fixed point and the bumper installation hole, so as to ensure that the bolt tool can thread and fix the left / right section of the bumper to the corresponding position of the cab front panel. The bottom limit sliding sleeve of the movable connection part of the hook tool is connected to the front of the bolt connection part, and the movable connection part of the hook can slide in the front of the bolt connection part, so as to solve the problem that the distance between the holes on the cab and the bumper is far and difficult to fix. Two sets of hook tools and bolt tools jointly hang the left and right sections of the bumper on the cab front panel, so that the left and right sections of the bumper can be electrophoresed on the vehicle. The length and angle of the hook of the hook tool can be changed according to actual needs to meet the needs of fixing the left and right sections of the three-section bumper of different models. The versatility of the bumper electrophoresis tool hanger is higher than that of the traditional hanger. Both the bolt fixture and the hook fixture are equipped with a hexagonal structure connected to the electric wrench drive, so that workers can quickly install and disassemble. Compared with the installation method of the bumper electrophoresis alone using wire binding, the bolt fixture and the hook fixture greatly save labor time and reduce labor costs; the left and right sections of the bumper are installed on the cab and electrophoresed on the vehicle, which frees up the hanging points occupied by the left and right sections of the bumper when they are electrophoresed separately, and improves the production capacity of the electrophoresis line. Taking the Jiefang J7 as an example, the on-vehicle electrophoresis fixture breaks through the traditional idea that metal bumpers can only be produced by electrophoresis alone with a hanger, and solves the following technical problems:
[0007] 1. Reduce the installation time of employees. The installation time of a single bumper is reduced from 168s / unit to 37s / unit.
[0008] 2. Reduce employees' disassembly work time. The installation time of a single bumper is reduced from 150s / unit to 33s / unit.
[0009] 3. Release the production capacity of the pre-treatment electrophoresis line. Based on the daily production of 80 J7s, 10 pre-treatment electrophoresis points will be released every day.
[0010] Expected benefits:
[0011] After the new tooling is put into use, the production capacity will be increased and the energy cost will be reduced. According to the statistics in the table below, the average hourly production consumption is 137 kWh and 102 m 3 Calculated by natural gas, when 50,000 J7s are produced that year, the pre-treatment electrophoresis cycle is 1.78 min / hang, 6250 hangs are saved, 185 hours of production are saved, and 25,345 kWh of electricity and 18,870 m3 are saved annually. 3 natural gas.
[0012]
[0013]
[0014] It can be seen from this that although the hanger of the present invention has a simple structure, it can achieve surprising beneficial effects in actual production applications.
[0015] Furthermore, the bolt tooling includes a first connecting part and a second connecting part, the first connecting part includes a first bolt head, a first limit plate and a first optical axis, the first bolt head is welded to the top end of the first optical axis, the first limit plate is an annular gasket that is matched and sleeved on the front part of the first optical axis, and the front end face of the first limit plate is welded and fixed to the rear end face of the first bolt head, the second connecting part is a stud structure, the second connecting part is coaxially welded to the rear end face of the first optical axis, and the maximum outer diameter of the second connecting part is smaller than the diameter of the first optical axis.
[0016] The first bolt head of the bolt fixture is welded to the top of the first optical axis. The first limit plate is an annular gasket sleeved on the first optical axis. The front end face of the first limit plate is welded and fixed to the rear end face of the first bolt head. The outer diameter of the first limit plate is slightly larger than the diameter of the bumper mounting hole, so that it can not only clamp the bumper mounting hole, but also will not block too much around the bumper mounting hole due to its large area and affect the electrophoresis effect of the bumper. The second connecting part is threadedly fixed to the threaded hole of the cab front panel. The bolt fixture is installed at the first fixed point. The present invention takes Jiefang J7 as an example. Before the left and right sections of the bumper are fixed to the cab, the left and right sections of the bumper are rotated 90 degrees from the normal installation position to the center position of the bumper and placed horizontally on the cab front panel. A bolt fixture and a hook fixture are used to fix the two fixed points in the middle and bottom of the left / right section of the bumper, and ensure that there is no interference point between the cab and the bumper.
[0017] Furthermore, the bent hook movable connection part includes a hook body and a tubular connection part. The hook body is an approximately L-shaped structure, and a bent hook is provided at one end of the hook body. The tubular connection part is a short circular tube, and the other end of the hook body is welded to the outer circumferential surface of the tubular connection part. The tubular connection part is limitedly slidably sleeved on the front of the bolt connection part.
[0018] The hook body of the hook movable connection is an approximately L-shaped structure, and the bending arc root of the hook at the top of the hook body and the length of the hook body are designed according to actual usage; a tubular connection part is welded to the bottom of the hook body, and the tubular connection part is limitedly slidably sleeved on the front part of the bolt connection part, so that the tubular connection part can slide freely on the front part of the bolt connection part or rotate circumferentially around the bolt connection part with the hook body, so as to ensure that the bumper mounting hole at the second fixed point and the threaded hole of the cab front panel can be fixedly connected by the hook tooling.
[0019] Furthermore, the bolt connection part includes a second bolt head, a second optical axis, a second limit plate, a third limit plate and a threaded part, the second bolt head is welded to the top end of the second optical axis, the second limit plate and the third limit plate are both annular gaskets, the second limit plate and the third limit plate are fixed on the second optical axis with an interval sleeve, and the front end face of the second limit plate is welded and fixed to the rear end face of the second bolt head, the tubular connection part is limited and slid between the second limit plate and the third limit plate, the threaded part is a stud structure, the threaded part is coaxially welded to the rear end face of the second optical axis, and its maximum outer diameter is smaller than the diameter of the second optical axis.
[0020] The second bolt head of the bolt connection part is welded to the top of the second optical axis. The second limiting plate and the third limiting plate are both annular gaskets, which are used to limit the tubular connection part of the hook fixture so that it can only slide between the second limiting plate and the third limiting plate and will not fall out of the second optical axis. The threaded part is used to be threadedly fixedly connected with the threaded hole of the cab front panel at the second fixed point.
[0021] Furthermore, the overall bending direction of the hook of the hook body is consistent with the direction of the front end of the second bolt head, and the hook tip of the hook is inclined downward.
[0022] The overall bending direction of the hook at the top of the hook body is consistent with the direction of the front end of the second bolt head, that is, the hook is hooked on the bumper mounting hole after passing out from the inner wall of the bumper mounting hole; the hook tip is tilted downward to ensure that the hook tooling is not easy to fall off from the bumper mounting hole. The threaded part of the bolt connection part is then threadedly fixed to the threaded hole of the cab front panel to finally achieve the fixation of the second fixing point. The bolt tooling and the hook tooling fix the left / right section of the bumper on the cab front panel.
[0023] Furthermore, the first bolt head and the second bolt head are both external hexagonal structures and have the same size.
[0024] The first bolt head and the second bolt head have the same shape and size, both of which are external hexagonal shapes, and are used to connect with the socket adapter of the electric wrench. The matching use of the electric wrench can further improve production efficiency and shorten the speed of installing or removing the bumper.
[0025] Furthermore, it also includes a bumper, which includes a left bumper section, a middle bumper section and a right bumper section. The left bumper section and the right bumper section are symmetrically arranged at the left and right ends of the middle bumper section. The middle and bottom of the left bumper section / the right bumper section are provided with multiple mounting holes. The bolt tooling is passed through the corresponding mounting holes in the middle of the left bumper section / the right bumper section. The hook of the hook tooling hooks the corresponding mounting holes at the bottom of the left bumper section / the right bumper section and the hook tip passes from the inner wall of the bumper to the outer wall.
[0026] The left and right sections of the three-section bumper are provided with multiple mounting holes in the middle and bottom. When the left and right sections of the bumper are mounted on the front panel of the cab, the left and right sections of the bumper are rotated 90 degrees from the normal mounting position to the middle position of the bumper, so that the left and right sections of the bumper remain in a horizontal position during mounting. The left and right sections of the bumper are provided with multiple mounting holes in the middle and bottom. The bumper is compared with the front panel of the cab in the 3D design software, and the suitable first and second fixing points are found in the middle and bottom of the left / right section of the bumper. The bolt tool is inserted into the mounting hole in the middle of the left / right section of the bumper and the threaded hole of the front panel of the cab for threaded fixing, completing the fixing at the first fixing point; the hook of the hook tool is hooked into the suitable mounting hole at the bottom of the left / right section of the bumper, and the hook tip is passed from the inner wall of the left / right section of the bumper to the outer wall. The threaded part of the hook tool is threadedly fixed to the threaded hole at the bottom of the cab outer panel, completing the fixing at the second fixing point. The first fixing point and the second fixing point jointly fix the left section / right section of the bumper to the outer panel of the cab, so that it can be electrophoresed with the vehicle.
[0027] A method for using a bumper electrophoresis tooling hanger includes the following steps:
[0028] S10. In the 3D design software, the left and right sections of the bumper are rotated 90 degrees from the normal installation position to the center of the bumper and placed horizontally on the front panel of the cab, and compared with the front panel of the cab in the digital model, and two fixing points of the left and right sections of the bumper are selected respectively by bolt fixtures and hook fixtures, and it is ensured that there is no interference point between the cab and the bumper;
[0029] S11. When fixing and hanging, rotate the left section of the bumper 90 degrees from the normal installation position to the center of the bumper and place it horizontally on the front panel of the cab, ensuring that the bumper installation surface fits the front panel of the cab and does not exceed the linear body passability, and other parts do not interfere with the cab and deform;
[0030] S12. Fixing the first fixed point of the left section of the bumper: According to the first fixed point selected by the three-dimensional design software, by moving the left section of the bumper in a small range, a bumper mounting hole directly opposite to the selected cab front wall panel threaded hole is found in the middle of the left section of the bumper, and a bolt tool is inserted into the bumper mounting hole and the cab front wall panel threaded hole in sequence, so that the first bolt head and the first limit plate limiter are exposed outside the bumper mounting hole, and the second connection part of the bolt tool is threadedly fixedly connected with the cab front wall panel threaded hole, thereby completing the fixing of the first fixed point of the left section of the bumper;
[0031] S13. Fixing the second fixing point of the left section of the bumper: According to the second fixing point selected by the 3D design software, the threaded hole of the cab front panel at this point is not blocked by the bumper. Find a bumper mounting hole adjacent to and matching the threaded hole of the cab front panel at the bottom of the left section of the bumper, hook the hook of the hook tool into the bumper mounting hole first, and then insert the threaded part of the hook tool into the threaded hole of the cab front panel for fixed connection, ensuring that the hook tool will not fall off from the bumper mounting hole, and complete the fixing of the second fixing point of the left section of the bumper;
[0032] S14. When fixing and hanging, rotate the right section of the bumper 90 degrees from the normal installation position to the center of the bumper and place it horizontally on the front panel of the cab, ensuring that the bumper installation surface fits the front panel of the cab and does not exceed the linear body passability, and other parts do not interfere with the cab and deform;
[0033] S15. Fixing the first fixed point of the right section of the bumper: according to the first fixed point selected by the three-dimensional design software, by moving the right section of the bumper in a small range, find a bumper mounting hole in the middle of the right section of the bumper that is directly opposite to the selected threaded hole of the cab front wall panel, insert the bolt tool into the bumper mounting hole and the threaded hole of the cab front wall panel in sequence, so that the first bolt head and the first limit plate limit are exposed outside the bumper mounting hole, and the second connection part of the bolt tool is threadedly fixedly connected with the threaded hole of the cab front wall panel, thereby completing the fixing of the first fixed point of the right section of the bumper;
[0034] S16. Fixing the second fixed point of the right section of the bumper: According to the second fixed point selected by the 3D design software, the threaded hole of the cab front panel at this point is not blocked by the bumper. Find the bumper mounting hole adjacent to and matching the threaded hole of the cab front panel at the bottom of the right section of the bumper, hook the hook of the hook tool into the bumper mounting hole first, and then insert the threaded part of the hook tool into the threaded hole of the cab front panel to fix the connection, ensure that the hook tool will not fall off from the bumper mounting hole, and complete the fixing of the second fixed point of the right section of the bumper.
[0035] Furthermore, the second fixing point has a bumper mounting hole and a cab front panel threaded hole that are directly opposite to the hole position, and the second fixing point can be directly fixedly connected using another bolt tooling pair.
[0036] If you find the bumper mounting hole and the cab front panel threaded hole facing the hole position when selecting the second fixing point, you can directly use another bolt tool to fix the connection without having to use the hook tool for fixing. You should choose the appropriate tool for fixing according to the actual situation.
[0037] Furthermore, the outer diameter of the first limiting plate is 2-3 mm larger than the diameter of the bumper mounting hole.
[0038] The first limit plate can be stuck on the bumper mounting hole at the first fixed point, so that the bumper mounting hole will not fall out from the first limit plate and the first bolt head. The outer diameter of the first limit plate should be larger than the diameter of the bumper mounting hole, but in order to avoid the first limit plate being too large to block the bumper and affect the electrophoresis effect, the outer diameter of the first limit plate is 2-3mm larger than the diameter of the bumper mounting hole.
[0039] Compared with the prior art, the present invention has the following beneficial effects:
[0040] 1. The hook fixture and bolt fixture of the present invention break through the traditional idea that metal bumpers can only be produced by electrophoresis alone. The on-board electrophoresis fixture connects the left and right sections of the bumper to the cab respectively. The left and right sections of the bumper are completely fitted to the front wall of the cab, and other parts do not interfere with the cab and deform, ensuring the quality of the on-board electrophoresis of the left and right sections of the bumper;
[0041] 2. The hook fixture and bolt fixture of the present invention have simple structure, low cost, can be used in conjunction with an electric wrench, are easy to use, greatly shorten the time for mounting and disassembling the left and right sections of the bumper, and save labor costs;
