Description
Technical Field
The utility model belongs to the machining technology relates to an inclined plane location hold-down mechanism.
Background
The pressing is a necessary key step in the part machining process, and the actual pressing effect often determines the part machining quality. In practical application, the pressing direction of a non-horizontal plane is often needed, and meanwhile, the pressing surface is small and the periphery of the pressing surface needs to be machined.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: there is a need for a positioning and pressing integrated mechanism that can achieve the purpose of pressing while achieving positioning through a positioning hole.
The technical scheme of the utility model is that:
in a first aspect, a bevel positioning and pressing mechanism is provided, which includes: the fixture comprises a fixture body, a thread positioning bush, a conical washer, a hexagonal nut with a shoulder, a spherical washer and a positioning bolt;
the thread positioning bush is arranged at the upper end of the step positioning hole of the fixture body through tight fit, so that the end surface of the thread end of the thread positioning bush is attached to the bottom surface of the step positioning hole; the end surface of the other end of the thread positioning bush is lower than the positioning surface of the clamp body; the conical surface of the conical washer is matched with the spherical surface of the spherical washer, the plane of the conical washer is attached to the substitute processing part, and the plane of the spherical washer is attached to the hexagonal nut with the shoulder; a screw rod of the positioning bolt sequentially passes through the hexagonal nut with the shoulder, the spherical washer, the conical washer and the center hole for replacing a machined part to the threaded positioning bush; and the positioning bolt is fastened so that the hexagonal nut with the shoulder compresses the spherical washer and the spherical washer compresses the conical washer, and the conical washer compresses the machined part to the clamp body.
Further, the mechanism further comprises: a cylindrical pin;
the cylindrical pin sequentially penetrates through the clamp body, the thread positioning bush and the positioning bolt, and is limited when penetrating through the clamp body, the thread positioning bush and the positioning bolt.
Further, the outer diameter of the thread on the screw is smaller than the diameter of the positioning part.
Furthermore, the positioning hole is a step hole with three steps and upward steps; the hole of the first step is an avoiding hole, and the depth and the size of the avoiding hole are determined by the shape of the part to be processed; a threaded positioning bushing is arranged and positioned in the hole of the second step; the diameter of the third step is larger than the external diameter of the screw thread.
Furthermore, the nut of the positioning bolt is an outer hexagon nut.
Further, the inclination of the positioning hole is determined by the inclination of the part.
The utility model has the advantages that: the problem that parts are easy to twist and deform when the parts on the inclined plane are compressed by a common pressing plate is successfully solved, meanwhile, the parts are successfully compressed and positioned at the same time, the operation process is simplified, the requirement of rapid positioning and clamping of the parts is met, the problem that the parts are inconvenient to compress due to the fact that the compressing surface of the parts is too small is solved, the overall structure of the tool is simplified, and a novel compressing and positioning mode is provided for achieving positioning and compressing of the parts on the inclined plane.
Drawings
Fig. 1 is a schematic structural view of an inclined plane positioning and pressing mechanism provided by the present invention.
Detailed Description
The present invention will be described in further detail below.
As shown in fig. 1, the utility model provides a structural schematic diagram of an inclined plane positioning and pressing mechanism.
The mechanism comprises: the fixture comprises a fixture body 1, a threaded positioning bush 2, a cylindrical pin 3, a conical washer 4, a hexagonal nut with shoulder 5, a spherical washer 6, a machining part 7 and a positioning bolt 8.
The utility model discloses an installation as follows:
the thread positioning bush 2 is installed at the upper end of the step positioning hole in the clamp body 1 through tight fit, so that the plane of one end of the thread positioning bush is attached to the bottom surface of the step hole;
then inserting the positioning bolt 8 into the positioning hole of the threaded positioning bush 2 to ensure that the positioning surface of the positioning bolt 8 is attached to the bottom surface of the positioning end of the threaded positioning bush 2, then drilling a through hole with the diameter of 30 percent or less of the positioning bolt from the side surface through the axis of the positioning bolt 8 and the position vertical to the axis of the positioning bolt 8, and installing a cylindrical pin 3 in the through hole to prevent the positioning bolt from rotating or loosening;
penetrating a positioning hole of the part 7 through one end of the positioning bolt extending out, and attaching the positioning hole to a positioning surface of the fixture body;
then, a central hole of the conical washer 4 penetrates through an extending end of the positioning bolt 8, one planar surface of the conical washer 4 is enabled to be attached to a pressing surface of the part 7, a central hole of the spherical washer 6 penetrates through the extending end of the positioning bolt 8, and at the moment, one spherical end of the spherical washer 6 is attached to the conical surface of the conical washer 4;
then, the hexagonal nut with the shoulder 5 is installed into the extending end of the positioning bolt 8 through thread matching, and the hexagonal nut with the shoulder 5 is screwed clockwise to press the spherical washer 6 tightly so as to press the part tightly, and then the machining process is started;
after the machining is finished, the hexagonal nut with the shoulder 5 is rotated anticlockwise to be loosened until the hexagonal nut with the shoulder 5 is taken out, then the spherical washer 6 and the conical washer 4 are taken out in sequence, and then the part is taken out to finish the integral machining process;
after the completion, the conical washer 4, the spherical washer 6 and the hexagonal nut with shoulder 5 are sequentially arranged so as to be convenient for the storage and the preservation of the mechanism.
