Abstract
New-type axle type part alignment frock has two "V" shaped iron (2), its characterized in that: two V-shaped irons are welded on a flat plate (1), V-shaped grooves of the two V-shaped irons (2) are longitudinally arranged on the same axis, arc surfaces matched with corresponding excircles of the shaft parts are respectively machined on V-shaped groove inclined planes of the two V-shaped irons (2), and a clearance groove (3) lower than the maximum positive work difference size of the excircles of the shaft parts is formed in the bottom of the V-shaped groove of the V-shaped iron. The shaft can be aligned by placing the shaft on the tool, or only a copper sheet is padded between the corresponding excircle of the shaft part and the arc surface. The processing efficiency and the product quality are improved in production.
Description
The technical field is as follows:
the utility model relates to a be used for 600 tons of crane axle class part keyway processing frocks.
Background art:
the transmission shaft of the upper wheel of the crane has higher precision requirement of the shaft and strict requirement on the position of key groove machining, so that the requirement on the alignment precision of a workpiece before machining is correspondingly improved. Because the workpiece is a stepped shaft, the existing alignment tool is provided with two V-shaped irons, the two V-shaped irons are needed to be padded at the two ends of the shaft in the alignment and fixing process, the horizontal alignment of the workpiece is adjusted by using a gasket and a copper sheet, and the linear alignment of the workpiece is adjusted by moving the position of the V-shaped iron.
The invention content is as follows:
the utility model discloses to above-mentioned alignment time overlength, provide a simple structure and need not the newfashioned axle type part alignment frock of many times alignment before processing, make into monolithic stationary with two "V" shaped iron.
The utility model discloses new-type axle type part alignment frock (see the attached), there are two "V" shaped iron (2), its characterized in that: two V-shaped irons are welded on a flat plate (1), V grooves of the two V-shaped irons (2) are longitudinally arranged on the same axis, arc surfaces matched with corresponding excircles of shaft parts are respectively machined on V groove inclined surfaces of the two V-shaped irons (2), and a clearance groove (3) with the size lower than the maximum positive working difference of the excircles of the shaft parts is arranged at the bottom of the V groove of the V-shaped irons. Therefore, when the alignment is right, only the copper sheet is needed to be padded between the corresponding excircle of the shaft part and the arc surface. The first shaft is just needed to be found, the straight line of the rear shaft is basically not changed, and only the copper sheet is padded between the corresponding excircle of the shaft part and the arc surface. Generally, the tolerance change is only a few times, and the adjustment can be realized only by using a copper sheet.
The utility model discloses further technical solution is: firstly, two pieces of V-shaped iron are welded and fixed on a whole plate, then the inclined planes of the two pieces of V-shaped iron are processed into the shape of an arc surface with the same size as the shaft diameter, the circumferential length of the arc surface is about one fourth of the whole circle, a clearance groove is processed at 1/2 length of the bottom of the arc surface, and the height is about 0.2mm.
The utility model discloses newfashioned axle type part alignment frock puts the axle just can the alignment on the frock, perhaps only needs axle type part to correspond and has filled up the copper sheet between excircle and the arc surface. The processing efficiency and the product quality are improved in production.
Description of the drawings:
FIG. 1 is a schematic diagram of a front view of the structure of the present invention; fig. 2 is a schematic diagram of a right side view of the present invention.
FIG. 3 is a schematic view of the front view of the utility model in use; fig. 4 is a right side view of the usage state of the present invention.
The specific implementation mode is as follows:
the embodiments of the present invention will be further explained with reference to the drawings.
This kind is as shown in the figure the utility model discloses new-type axle type part alignment frock (see attached 1, 2), there are two "V" shaped iron 2, its characterized in that: two pieces of V-shaped iron are welded on a flat plate 1, V grooves of the two pieces of V-shaped iron 2 are longitudinally arranged on the same axis, arc surfaces matched with corresponding excircles of shaft parts are respectively processed on the inclined surfaces of the V grooves of the two pieces of V-shaped iron 2, and a clearance groove 3 with the maximum positive work difference size lower than the excircles of the shaft parts is arranged at the bottom of the V groove of the V-shaped iron. Therefore, when the alignment line is processed, a novel shaft part alignment tool is used, as shown in fig. 2. Before processing, a first stepped shaft is placed on the V-shaped iron, the straight line alignment is found according to the side edge of the bottom plate of the V-shaped iron, and the horizontal alignment is found according to the excircle of the top end of the stepped shaft. Firstly, two V-shaped irons are welded and fixed on a whole plate and fixed on a workbench of a machining center, then inclined planes of the two V-shaped irons are machined to be in the shape of an arc surface with the same size as the shaft diameter, the circumferential length of the arc surface is about one fourth of the whole circle, a hollow cutter groove is machined in the length of 1/2 of the bottom of the arc surface, and the height of the hollow cutter groove is about 0.2mm. The straight line of the shaft of the same batch of stepped shafts processed later basically does not change, and only the corresponding excircle and the arc surface of the shaft parts of the same batch and the same specification are padded with copper sheets. Generally, the tolerance change is only a few times, and the adjustment can be realized only by using a copper sheet. Therefore, the time for subsequent processing alignment is greatly shortened, the efficiency is improved, and the quality of processing form and position tolerance can be effectively ensured.
