Abstract

The utility model relates to a processing jig for a thimble type work piece, comprising a three jaw chuck, a handle, an equal-height supporting pillar, a positioning bolt, two fixed blocks, a guide pin, a lifting plate, a gripper base, a poisoning plate, a rivet, a connecting plate, a top block and a positioning block, wherein the three jaw chuck is fixed with the connecting plate; the equal-height supporting pillar passes through the lifting plate; the upper end of the equal-height supporting pillar is fixed with the connecting plate, and the lower end thereof is fixed with the gripper base; the lifting plate is matched with the positioning bolt to move up and down; the two fixed blocks are respectively arranged on the lifting plate; the guide pin is arranged in the fixed block; the handle is arranged in the top block through the other fixed block; the top block is movably connected with the handle by a dowel; the positioning block is arranged in a U-shaped groove on the lifting plate in a sliding manner; and the rivet passes through a center hole of the positioning plate and is fixed with the gripper base. The processing jig adopting the gripper reduces the adjusting time on a machine tool, improves the utilization of an automatic device, meets the processing needs of the machine tool, and simultaneously, avoids the precision influence of the work pieces processing due to the repeated adjustment of the gripper, thus guaranteeing the product quality and improving the production efficiency.

Description

Thimble class workpiece processing jig

Technical field

The utility model relates to the tool of holding workpiece, particularly a kind of thimble class workpiece processing jig that is applicable to the processing mobile phone plastic.

Background technology

General workpiece processing all on lathe, carrying out clamping location, because thimble class workpiece processing and loading clamp precision height, it is longer that the clamping adjustment makes the lathe stagnation stand-by period on lathe, and alignment jig causes the accuracy of workpiece processing easily repeatedly, so that influences product quality and production efficiency.

Summary of the invention

In view of above-mentioned prior art situation, the utility model is reduced in the time of adjustment on the lathe in order to improve the automatic equipment utilization rate, satisfies the machine tooling needs, designs a kind of thimble class workpiece processing jig especially.

The technical scheme that the utility model is taked for achieving the above object is: a kind of thimble class workpiece processing jig, it is characterized in that: comprise scroll chuck, handle, contour support column, alignment pin, two fixed blocks, pilot pin, lifter plate, clamp base, spacer, blind rivet, connecting plate, jacking block and locating piece, wherein, scroll chuck is fixedlyed connected with connecting plate, lifter plate is provided with three through holes and U type groove, three contour support columns pass three through holes on the lifter plate respectively, fixedly connected with connecting plate in its upper end, fixedly connected with clamp base in the lower end, lifter plate and alignment pin are engaged in shift position on three contour support columns, two fixed blocks are fixedly mounted on the lifter plate respectively, pilot pin is contained in the fixed block, handle passes another fixed block and packs in the jacking block, jacking block flexibly connects by pin and handle, locating piece is slidingly mounted in the U type groove that is provided with on the lifter plate, and centre bore and clamp base that blind rivet passes spacer are spirally connected fixing.

The beneficial effect that the utility model produced is: adopt these anchor clamps, reduced the time of adjustment on lathe, improved the automatic equipment utilization rate, satisfy the machine tooling needs, also avoided simultaneously because of the alignment jig precision influence that processing brings to workpiece repeatedly, thereby guaranteed product quality, improved production efficiency.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to Fig. 1,2,3,4, thimble class workpiece processing jig comprises scroll chuck 1, handle 2, contour support column 3, alignment pin 4, two

fixed blocks

5 and 7, pilot pin 6, lifter plate 8, clamp base 9, spacer 10, blind rivet 11, connecting plate 12, jacking block 13 and locating piece 14, wherein, scroll chuck 1 and connecting plate 12 are fixedlyed connected by screw, lifter plate 8 is provided with three through holes and U type groove, three contour support columns 3 pass three through holes on the lifter plate 8 respectively, fixedly connected by screw with connecting plate 12 in its upper end, lower end and clamp base 9 are fixedlyed connected by screw, lifter plate 8 is engaged in shift position on three contour support columns 3 with alignment pin 4, two

fixed blocks

5 and 7 are fixedly mounted on the lifter plate 8 by screw respectively, fixed block 5 is provided with tapped shoulder hole, be provided with screw and spring in the hole, pilot pin 6 is contained in the shoulder hole of fixed block 5, utilize the spring activity orientation, fixed block 7 is provided with tapped through hole, handle 2 is provided with thread and cannelure, jacking block 13 is provided with blind hole and locating hole, handle 2 passes fixed block 7 and packs in the blind hole of jacking block 13, jacking block 13 flexibly connects by pin 15 and handle 2, size according to workpiece, on a side of locating piece 14, be provided with a series of step surface, locating piece 14 is slidingly mounted in the U type groove that is provided with on the lifter plate 8, cooperate jacking block 13 finish to the workpiece bottom standstill face holding action, centre bore and clamp base 9 that blind rivet 11 passes spacer 10 are spirally connected fixing.

This tool is applicable to and is processed with the standstill face and do not have the thimble class workpiece of standstill face diameter less than 12mm, and clamping by scroll chuck and bottom hold assembly cooperate with the workpiece standstill face, realize the fastening clamp of thimble under the prerequisite that guarantees the clamping workpiece precision.

Tool workflow and principle: workpiece is contained on the tool, at first use less chucking power with piece-holder on scroll chuck 1, guarantee the height that workpiece exposes, by adjusting the height of lifter plate 8, to adapt to the length of workpiece.Hole on three contour support columns 3 cooperates the height that is used for determining lifter plate 8 with alignment pin 4.The bottom of workpiece is clamped between jacking block 13 and the locating piece 14, running fix piece 14 is fitted with the standstill face of thimble class workpiece, promoting jacking blocks 13 by handle 2 moves forward and backward and regulates jacking block 13 holding workpieces, guarantee that the workpiece standstill face after fastening is consistent with processing request, avoid the rotation in workpiece deformation and the process, thereby realized that workpiece is fastened on the purpose on the tool.Cooperate the Erowa machine to set device outward and carry out the outer preset operation of machine, after preset is finished, repeat to check for several times the perpendicularity of workpiece, detect and guarantee that specification error is lower than 0.005mm.
