Abstract
The utility model relates to a clamp of a horizontal milling machine for milling a 200*50 side bearing, which mainly solves the problems that in the prior art, a vertical milling cutter of a side bearing cannot process the 200*50 side bearing easily, the processing speed is slow, and the processing rejection ratio is high. The clamp is characterized in that the right side of a vertical plate (3) is fixedly connected with an upper pressing plate (5) and a lower pressing plate (11) at intervals in a vertical manner by an upper stud bolt (6) and a lower stud bolt (12), wherein the inverted L-shaped upper pressing plate is formed by the vertical connection of a cross plate at the upper part and a vertical plate at the lower part, the cross plate is fixed on the vertical plate, and the lower end of the vertical plate is suspended; the lower part of the upper stud bolt is fixedly connected with a jackscrew plate (7), two jackscrews B (9) are arranged at the right end of the jackscrew plate; the lower pressing plate is vertical and is connected at the right end of the lower stud bolt, and the vertical plate at the upper part of the lower stud bolt is connected with two positioning pins. The clamp of the horizontal milling machine for milling the 200*50 side bearing can be used for clamping and fixing rapidly and accurately and is high in production efficiency.
Description
Technical field
The utility model relates to a kind of rolling stock accessory that is used for and produces used positioning fixture, particularly a kind of 200*50 milling clamper for sleeping in that mills.
Background technology
Side bearing is the strength member in the railway goods train bogie, and it is installed in the bolster in every bogie, forms elastic side bearing with elastic side bearing body, side bearing wear plate, roller, Roller Shaft, adjustment backing plate and backing plate.Elastic side bearing plays interception when vehicle rollover and sideslip.The version of side bearing and performance are directly connected to the operation critical speed of crawling of vehicle, the important dynamics performance indications such as coefficient, wheel off-load rate, curving performance of derailing.Therefore whether reasonable its processing technology of side bearing traffic safety that directly influences the permutation lorry be closely related.Original processing mode adopts line earlier, the mode of back end mill processing.Process tool is the 63*50 cylindrical milling cutter, and operation is loaded down with trivial details, and process velocity is slow.200*50 dimensional requirement and symmetry require all higher being not easy to guarantee that percent defective is higher.
Summary of the invention
The utility model technical problem to be solved is to overcome the existing side bearing slotting cutter 200*50 dimensioned difficulty process velocity that exists in the background technology to reach the high problem of processing percent defective slowly; And a kind of 200*50 of milling is provided the milling clamper that crouches; This mill 200*50 crouch milling clamper can press from both sides quickly and accurately establish fixing; Production efficiency is high, and qualified products article rate is higher.
The utility model solves its problem and can reach through following technical scheme: this mills 200*50 milling clamper for sleeping in and comprises base plate; Described plate upper surface vertically is provided with a riser, is arranged with 2 alignment pins on the anterior vertical direction in riser right side, and rear portion, riser right side is provided with jackscrew A; Described jackscrew A is connected on the jackscrew plate; Described riser right side through last stud and down the stud perpendicular separation be fixedly connected with 2 block pressur plates, be respectively top board and lower platen, wherein the top board of " fall L " type vertically is formed by connecting a transverse slat on top and a riser of bottom; Transverse slat is fixed on the riser, dangles in the riser lower end; Last stud bottom is fixedly connected with the jackscrew plate, and jackscrew plate right-hand member is provided with 2 jackscrew B; Lower platen is a vertical plate, is connected down the right-hand member of stud, connects 2 alignment pins on the riser on following stud top.
The utility model and above-mentioned background compared with techniques can have following beneficial effect: this mills 200*50 and crouches milling clamper owing to adopt said structure, can the side bearing blank be pressed from both sides quickly and accurately to establish fixingly, and on the milling machine that crouches, processes the side bearing finished product.Saved the cutter expense and alleviated operator's work difficulty, guaranteed the quality of side bearing, production efficiency is high, is fit to produce in enormous quantities, and worker, anchor clamps are once invested little, have good and economic, produce a desired effect.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is right views of accompanying drawing 1;
Accompanying drawing 3 is structural representations of the utility model processing work side bearing.
Among the figure: 1-base plate, 2-jackscrew A, 3-riser, 4-gusset, 5-top board, the last stud of 6-, 7-jackscrew plate, 8-side bearing, 9-jackscrew B, 10-alignment pin, 11-lower platen, stud under the 12-.
The specific embodiment:
To be described further the utility model below in conjunction with accompanying drawing:
Accompanying drawing 1 combines shown in the accompanying drawing 2, and this mills 200*50 milling clamper for sleeping in and comprises base plate 1, and described base plate 1 upper surface vertically is provided with a riser 3; Described riser 3 left vertical are fixed with gusset 4, are arranged with 2 alignment pins 10 on the anterior vertical direction in riser 3 right sides, and rear portion, riser 3 right side is provided with jackscrew A2; Jackscrew A2 is connected on the jackscrew plate; Described riser 2 right sides through last stud 6 and down stud 12 perpendicular separations be fixedly connected with 2 block pressur plates, be respectively top board 5 and lower platen 11, wherein the top board 5 of " fall L " type vertically is formed by connecting a transverse slat on top and a riser of bottom; Transverse slat is fixed on the riser 3, dangles in the riser lower end; Last stud 6 bottoms are fixedly connected with jackscrew plate 7, and jackscrew plate 7 right-hand members are provided with 2 jackscrew B9; Lower platen 11 is a vertical plate, is connected down the right-hand member of stud 12, connects 2 alignment pins 10 on the riser 3 on following stud 12 tops.
It is as shown in Figure 3 that this mills the 200*50 workpiece side bearing 8 that milling clamper will fix that crouches.When the milling clamper that should crouch uses; Workpiece side bearing 8 bottom surfaces that will process are against on the riser 3; The side bearing front and back end is by alignment pin on the riser and jackscrew A2 location; Side bearing is fixed through jackscrew B9 and alignment pin on the jackscrew plate 7 up and down, and the side bearing left and right directions is by being located by top board 5 and lower platen 11.With work piece positioning tight after, process with gang tool.Reached riser and be not more than 0.02mm with respect to the perpendicularity of base plate, alignment pin is not more than 0.1mm with respect to the symmetry of base plate.
