Abstract
The invention discloses a clamp for machining inside diameters and outer diameters of fixed ball races. The clamp can simultaneously machine the inside diameters and the outer diameters of a plurality of fixed ball races; and the processed fixed ball races have good concentricity, high processing work efficiency and stable processing size. An underpan, connecting blocks and a briquette of the clamp are all circular; the connecting blocks and the underpan are concentric; the inside diameters of the connecting blocks are smaller than the inside diameter of the underpan; a part of connecting blocks are connected with the pan surface of the underpan; the other part of connecting blocks are respectively provided with two or more screw holes and two or more positioning pin mounting holes; the briquette is provided with two or more bolt connecting holes and two or more positioning pin connecting holes; one end of each positioning pin is tightly matched and connected with a corresponding positioning pin mounting hole; and the other end of each positioning pin is arranged in the corresponding positioning pin connecting hole; and each connecting bolt penetrates through a corresponding bolt connecting hole and is in threaded connection with a corresponding thread hole.
Description
Technical field
The present invention relates to a kind of aid of deciding Zhu Quan of processing, relate in particular to the anchor clamps that a kind of Che Dingzhu of being used for encloses inside and outside footpath.
Background technology
Thin thickness, the overall dimensions of deciding Zhu Quan are big, if adopt the single-piece Vehicle Processing being prone to cause its distortion when decide pearl circle clamping, and the inside and outside footpath of car need carry out twice clamping, thereby causes concentricity poor, and work efficiency is low, the size instability of processing.
Summary of the invention
Technical problem to be solved by this invention provides the anchor clamps that a kind of Che Dingzhu of being used for encloses inside and outside footpath; Use these anchor clamps to carry out the Vehicle Processing of inside and outside footpath to a plurality of Zhu Quan of deciding simultaneously; And the pearl of deciding of processing is enclosed good concentricity, the work efficiency height of processing, the dimensionally stable of processing.
The present invention includes chassis, contiguous block, briquetting, two or two above alignment pins and two or two above connecting bolts; It is circular that said chassis, contiguous block and briquetting all are; The internal diameter of contiguous block and contiguous block concentric with the chassis is less than the internal diameter on chassis; Part contiguous block is connected on the card on chassis; Two or more screwed holes and two or more alignment pin installing holes are set on another part contiguous block; On briquetting, be provided with and mutual two or more the corresponding bolt connecting holes of said two or more screwed holes, on briquetting, be provided with and mutual two or more the corresponding alignment pin connecting holes of said two or more alignment pin installing holes; One end of above-mentioned every alignment pin is installed in the corresponding alignment pin installing hole, and the other end places corresponding alignment pin connecting hole; Every connecting bolt passes corresponding bolt connecting hole respectively and is threaded with corresponding screwed hole.
When using the anchor clamps among the present invention, the chassis is connected on the headstock of lathe; Back out bolt; Briquetting is dismantled; Again a plurality of Ding Zhuquan to be processed are installed on the alignment pin, promptly through deciding deciding the hole of bead and will deciding the pearl snare on alignment pin of Zhu Quan; Through the alignment pin connecting hole on the briquetting briquetting is connected on the alignment pin then; Last connecting bolt passes the bolt connecting hole on the briquetting, passes the hole of bead of deciding of deciding Zhu Quan again, is threaded with screwed hole on the contiguous block of chassis.Use these anchor clamps to carry out the Vehicle Processing of inside and outside footpath to a plurality of Zhu Quan of deciding simultaneously, and processing decide pearl circle good concentricity, processing to decide the Zhu Quan distortion little, processing dimension is stable, uses these anchor clamps also to improve the work efficiency of processing.
Preferably, said screwed hole and alignment pin installing hole are respectively two; The line of centres of above-mentioned two screwed holes is through the center of contiguous block, and the line of centres of above-mentioned two alignment pin installing holes is through the center of contiguous block, and the line of centres of two screwed holes is vertical each other with the line of centres of two alignment pin installing holes.
Preferably, equally distributed bolt connecting hole more than three or three is being set on the chassis.
The bolt connecting hole that is provided with on the chassis can be convenient to the headstock of chassis through bolt and lathe and interconnect, thereby makes things convenient for anchor clamps to safeguard.
Figure of description
Fig. 1 is the structural representation of anchor clamps;
Fig. 2 is the cutaway view of A-A line among Fig. 1;
Fig. 3 is the cutaway view of B-B line among Fig. 1.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, the anchor clamps in this embodiment comprise chassis 1, contiguous block 2, briquetting 3, two alignment pins 4 and two connecting bolts 5; Said chassis 1, contiguous block 2 and briquetting 3 all are circular.
The internal diameter of the concentric and contiguous block 2 in contiguous block 2 and chassis 1 is less than the internal diameter on chassis 1.Part contiguous block 2 is connected on the card on chassis 1.Two screwed hole 2-1 and two alignment pin installing hole 2-2 are set on another part contiguous block 2.The line of centres of said two screwed hole 2-1 is through the center of contiguous block 2; The line of centres of said two alignment pin installing hole 2-2 is through the center of contiguous block 2, and the line of centres of two screwed hole 2-1 is vertical each other with the line of centres of two alignment pin installing hole 2-2.
Mutual two corresponding bolt connecting hole 3-1 with said two screwed hole 2-1 are set on briquetting 3, on briquetting 3, are provided with and mutual two the corresponding alignment pin connecting hole 3-2 of said two alignment pin installing hole 2-2.
One end of above-mentioned every alignment pin 4 is installed among the corresponding alignment pin installing hole 2-2, and the other end places corresponding alignment pin connecting hole 3-2.Every connecting bolt 5 passes corresponding bolt connecting hole 3-1 respectively and is threaded with corresponding screwed hole 2-1.
In addition, 1 four equally distributed bolt connecting hole 1-1 are set on the chassis.
