Abstract

The invention discloses a fixture for machining workpiece holes, and the fixture comprises a base, a positioning column, a stand column and a positioning mechanism, wherein the positioning column is arranged in the rear of the top of the base and used for positioning one end of a workpiece, the stand column is arranged in the center of the top of the base and used for supporting the machined end of the workpiece, and the positioning mechanism is used for tightly compressing the workpiece, the positioning mechanism comprises a compression block, a screw, a locknut, a bolt and a threaded hole, the compression block is horizontally arranged above the stand column, the screw vertically passes through one end of the compression block, the locknut is arranged below the compression block and screwed on the screw, the bolt vertically penetrates through the middle part of the compression block, the threaded hole is formed at the top of the base and matched with the bolt, the other end of the compression block is horizontally sunken inwards so as to form a groove, the groove is provided with an arc-shaped inner wall matched with the shape of the inner circular surface of a hole to be machined, the height of the workpiece is adjusted through the cooperation of the screw and the locknut, and the end part of the groove of the compression block directly tightly compresses the workpiece, so that in the process of machining, the deviation of the workpiece is effectively controlled, and thus the machining accuracy is high.

Description

A kind of anchor clamps for the processing work hole
Technical field
The present invention relates to a kind of anchor clamps for the processing work hole
Background technology
The processing in the hole of existing workpiece, employing is fixed the mode of non-processing place, by the not processed place of compact heap workpiece pressing, lathe moves downward from the top in the end processing of workpiece and portals, like this in the process of processing, the processed end of workpiece is subject to the displacement on the easy occurred level face of larger power, and then has affected machining accuracy
Summary of the invention
The purpose of this invention is to provide the directly anchor clamps that are used for processing work hole fixation workpiece processing end, that machining accuracy is high.
For achieving the above object, the invention provides a kind of anchor clamps for the processing work hole, one end of described workpiece is annulus, the other end is circular block, described anchor clamps comprise base, be arranged on the column that supports described workpiece at the center of described base top, the rear that is arranged on the top of described base is used for locating the locating dowel of described annulus position, be used for compressing the detent mechanism of described circular block, described detent mechanism comprises the compact heap that is horizontally set on described column top, vertically pass the screw rod of described compact heap one end, be positioned at the locking nut on the described screw rod of being spun on of described compact heap below, vertically pass the bolt at described compact heap middle part, the other end along continuous straight runs of the described compact heap formation groove that caves inward, the circular arc that the inwall of described groove is complementary for the inner peripheral surface shape with the hole to be processed of described workpiece, offer screwed hole at described base, described screwed hole and described bolt are complementary.
Preferably, offer vertical inner chamber at the top of described column, described inner chamber is connected with the outside by circular open.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect: the column with the inner chamber that is connected with the outside by circular open is set at the center of base top, in the base upper horizontal compact heap is set, the screw rod that vertically passes compact heap one end is set, the locking nut that is spun on the screw rod is being set below the compact heap, the bolt that vertically passes the compact heap middle part is set, the screwed hole that is complementary with bolt is set at base, offer the groove of level at the other end of compact heap, groove has the circular arc inwall that the inner headed face with the hole to be processed of workpiece is complementary, during processing work, can regulate by locking nut the height of compact heap, be bolted compact heap, by the displacement on the horizontal plane of indentation limitations workpiece, machining accuracy is high like this.
Description of drawings:
Accompanying drawing 1 is looked schematic diagram for master of the present invention;
Accompanying drawing 2 is schematic top plan view of the present invention.
The specific embodiment:
Referring to shown in Figure 1, rear at base 1 top arranges locating dowel 2, during processing work, the annulus of workpiece one end is set on the locating dowel 2, top center at base 1 arranges column 3, during processing work, column 3 supports the processed circular block of the workpiece other end, but the compact heap 4 at column 3 upper horizontal setting workpiece pressings, the screw rod 5 of an end that vertically passes compact heap 4 is set, the bottom of screw rod 5 is against the top of base 1, the locking nut 6 that is spun on the screw rod 5 is being set below the compact heap 4, screw rod 5, locking nut 6 cooperatively interacts and can regulate, the height of piece 4 is fixed and clamped, when needing to regulate the height of compact heap 4, locking nut 6 is unscrewed, and rotary screw 5 makes the height of compact heap 4 rise or descend, in the time of need to being fixed and clamped piece 4, screw locking nut 6, make it to be adjacent to the bottom of compact heap 4, the height of compact heap 4 is fixed, the bolt 7 that vertically passes compact heap 4 middle parts is set, be opened in the screwed hole at base 1 top, bolt 7 is complementary with screwed hole, and compact heap 4 can be the fulcrum rotation by bolt 7, after circular block one end of workpiece is put column 3 tops, rotate compact heap 4 to column 3 tops, reduce the height of compact heap 3, so that workpiece pressing.
Referring to shown in Figure 2, offer groove 8 at column 3 tops, groove 8 is connected with the outside by circular open, the diameter of circular open is not less than the internal diameter in hole to be processed, reserved so the lower row space that cutter penetrates machining hole, in the descending machining hole of cutter, can not contact with column 3 and damage, but offer the groove that caves inward 9 of horizontal direction at the other end of the workpiece pressing of compact heap 4, groove 9 has the circular arc inwall that the inner headed face with workpiece hole to be processed is complementary, contact with compact heap 4 when this has been avoided the descending machining hole of cutter equally and damage, compact heap 4 directly is pressed on workpiece end to be processed, fixed effect to workpiece is better, and machining accuracy is high

Claims (2)
