Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Refer to Fig. 1, subframe 201 of the prior art comprises crossbeam 202 and longeron 203, when making, first the two ends of two longerons 203 being welded by crossbeam 202, again subframe 201 being put afterwards and to subframe making frock, remaining crossbeam 202 being welded between two longerons 203.After subframe 201 being placed in prior art in subframe making frock, needing to be clamped subframe 201 by other clamping device, then carry out welding job.
Refer to Fig. 2-Fig. 6, subframe that the utility model first embodiment provides makes tooling clamping mechanism and comprises pedestal 101, pedestal 101 comprise up and down each two longer longitudinal axis, on vertical plane, connect the column of each longitudinal axis and connect the shorter transverse axis of each longitudinal axis in the horizontal plane.
The longitudinal axis of the end face of pedestal 101 is provided with 7 gripper shoes 102, and the both sides of each gripper shoe 102 are provided with location-plate 103, and gripper shoe 102 and location-plate 103 form positioner.Stiffener is provided with, to improve the intensity of location-plate 103 between location-plate 103 and gripper shoe 102.Subframe 201 can be placed on the working face of gripper shoe 102 formation, and two longerons of subframe 201 are positioned between the location-plate 103 of each gripper shoe 102 both sides.
Every two adjacent gripper shoes 102 are provided with a pair clamping cylinder 110 in opposite directions, by these clamping cylinders 110, subframe 201 can be clamped, facilitate follow-up welding job.
Certainly, also can establish a pair clamping cylinder 110 in each gripper shoe 102, the design provided in this design and the present embodiment, the quantity of clamping cylinder 110 adds one times, cost up, but clamping effect is better, therefore cuts both ways.
Clamping cylinder 110 is driven by hydraulic system and electric-control system, and this clamping cylinder also can be replaced with other retractor devices, such as cylinder or electric cylinder, and cylinder is driven by baric systerm and electric-control system, and electric cylinder is driven by motor and control system.
Clamping cylinder 110 may cause scuffing to subframe 201 when being clamped by subframe 201, subframe 201 is even made to be out of shape, in the present embodiment, the working face of each clamping cylinder 110 is provided with a cushion block, to increase the contact area of clamping cylinder 110 and subframe 201, reduce the pressure of clamping cylinder 110 pairs of subframes 201 during work according to this, reduce scuffing and the distortion of subframe 201.
The subframe of automobile is provided with numerous precise part, and these parts require higher to installation dimension, therefore need to keep its high accuracy at making subframe; And more difficult the size of control subframe in the manufacturing process of subframe at present, when welding subframe, often cause the distortion of subframe, and cause subframe dimensional accuracy lower.
Subframe, when welding, needs the clamping force that suitable, firmly not enough, subframe can be caused unstable, easily produce and rock during welding; Overexert, then subframe can be caused to scratch or distortion, and at present when subframe is clamped, often according to the micro-judgment of master worker, subframe clamps by hydraulic control system and electric-control system, and the experience of master worker not necessarily accurately, and therefore the precision of subframe is difficult to control.
In order to address this problem, in the present embodiment, the working face of clamping cylinder 110 is provided with a pressure sensor, and pressure sensor is connected with A/D converter, processor, display in turn.After clamping cylinder 110 touches subframe 201, pressure sensor can sense variable, this variable is passed to A/D converter, A/D converter changes this variable into numerical value passes to processor, display passed to by processor, by the display of this numerical value over the display, user can see the clamping force between clamping cylinder 110 and subframe 201 clearly; In the process clamped by subframe 201, this clamping force is in continuous change, and relative to each subframe, have the scope of a suitable power, by display, user sees that clamping force drops within this scope, namely stops continuing clamping.By such design, namely guarantee subframe to clamp, can ensure that again subframe can not produce distortion because of this clamping force, preferably resolve the problems referred to above.
After subframe 201 has welded, clamping cylinder 110 is unclamped, now needed that subframe 201 is moved to next station and process.Subframe that the present embodiment provides makes tooling clamping mechanism and also comprises a travel mechanism, uses the movement that this travel mechanism can realize subframe 201.
Travel mechanism comprises push rod 105 that the telescopic oil cylinder 104 be connected on pedestal 101 column is connected with telescopic oil cylinder 104, is located at the turning device be connected between every two gripper shoes 102 and with push rod 105; Each turning device comprises two ends and is rotationally connected with the rotating shaft 106 of pedestal 101 both sides, the connecting plate 107 be fixed in rotating shaft 106, is rotationally connected with carrying roller 108 between two connecting plates 107; Push rod 105 is rotatably connected to driver plate 109, driver plate 109 is fixedly connected with the rotating shaft 106 of each turning device.All carrying rollers 108 are in same plane.
After subframe 201 completes welding job in this frock, control telescopic oil cylinder 104 to stretch out, promote push rod 105, push rod 105 drives driver plate 109 to rotate, because driver plate 109 is fixedly connected with rotating shaft 106, therefore driver plate 109 drives rotating shaft 106 to rotate, and drives carrying roller 108 to overturn, is lifted by subframe 201 and move horizontally.It is simple that this subframe makes tool structure, is convenient to manufacture, and can realize easily locating when subframe 201 makes, and smoothly subframe 201 is moved to next station.
Because the width of subframe 201 is generally at more than 800mm, and this subframe makes in frock, the length of carrying roller 108 is consistent with the width of subframe 201, if the length of a carrying roller 108 is more than 800mm, then be difficult to ensure its precision, there is the problem that axiality is lower.Therefore, preferably, in the present embodiment, the rotating shaft 106 of each turning device is connected with two carrying rollers 108, and these two carrying rollers 108 are arranged side by side and are synchronized with the movement, and are connected with rotating shaft 106 respectively by connecting plate 107.Adopt above-mentioned design, required carrying roller 108 length is between 350mm-450mm, and the carrying roller 108 of this specification makes comparatively simple, and axiality easily ensures.
In the present embodiment, rotating shaft 106 with the mode that is rotationally connected of pedestal 101 is: pedestal 101 both sides are provided with bearing block 111, are provided with bearing 112 in bearing block 111, and the two ends of rotating shaft 106 are fixed in the inner ring of bearing 112.This connected mode is comparatively firm, and noise is lower, and easy access and replacing.
In the present embodiment, each parts of pedestal 101: the longitudinal axis, column, transverse axis all adopt angle steel to make, each tie point welding, can guarantee the firm of pedestal 101, also make the cost of this pedestal 101 lower.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
