Detailed Description
The utility model discloses a frock clamp is used in production in batches of high accuracy PETS part and speculum part, as shown in fig. 1, including chuck 1, base 2 and the tight cap of clamp 3, the upper portion of base is work piece installation department 21, be equipped with work piece base mounting hole 211 on the top surface of work piece installation department, be equipped with the external screw thread on the outer cylinder of work piece installation department. The clamping cap is in a cover shape with internal threads, and the top surface of the clamping cap is provided with a through hole 31 which penetrates through the clamping cap from top to bottom. The depth of the workpiece base mounting hole is not larger than the height of a base of a workpiece to be mounted, so that the clamping cap can firmly press the base of the workpiece in the workpiece base mounting hole, and the workpiece is fixed in the height direction. In the mounting state, the clamp cap is fastened on the workpiece mounting portion 21 from top to bottom, the end face of the inner side of the clamp cap is pressed on the top face of the workpiece, and the clamp cap is fixedly connected with the workpiece mounting portion through the inner thread of the clamp cap. The contour of the through hole is positioned in the contour of the workpiece base mounting hole on the same horizontal projection plane or the contour of the through hole and the workpiece base mounting hole are partially intersected, the chuck is positioned at the lower part of the base, and the clamping jaws of the chuck clamp and fix the lower part 22 of the base.
As a preferred scheme, the through hole is vertically opposite to the center of the workpiece base mounting hole.
The horizontal contour of the workpiece base mounting hole is consistent with that of a base (generally a process base) to be clamped with a workpiece, the workpiece base mounting hole is generally polygonal so as to prevent circumferential rotation of the workpiece, and the workpiece base mounting hole is preferably rectangular and simpler in structure.
The horizontal linear dimension of the workpiece base mounting hole can be manufactured according to the unilateral matching tolerance of the workpiece base to be mounted in the corresponding direction, which is +0.02 mm. Of course, the machining precision of the workpiece is specifically determined by reference. The higher the requirement on the machining precision of the workpiece is, the smaller the fit clearance between the workpiece base mounting hole and the base of the workpiece is, and the assembly precision between the workpiece base mounting hole and the base of the workpiece is at least not lower than the required precision of the workpiece.
The shape of the base is not limited, and the base is preferably in a revolving body structure due to the requirement of structure simplification, so that the base is convenient to process.
The lower part of the base is mainly used for clamping and fixing the chuck, and the size is not limited. In the embodiment shown in the drawings, the base is preferably arranged in a stepped shaft structure with a large upper part and a small lower part, namely, the diameter of the upper part of the base is larger than that of the lower part of the base, when the chuck is used for clamping, the jaws are clamped on the outer cylindrical surface of the lower part of the base, and the top surfaces of the jaws are abutted on the step surface between the upper part and the lower part of the base. Of course, the diameter of the lower portion of the base can be larger than that of the upper portion, correspondingly, an inner hole with a downward opening can be formed in the lower portion of the base, and clamping jaw clamping can be achieved by using the cylindrical surface of the inner hole and the inner end face of the inner hole as positioning faces.
The workpiece mounting portion and the clamping cap may each have a radially extending pin bore 212 and 32, respectively, through which a locating pin 4 simultaneously passes and engages in the mounted state. The base is connected with the clamping cap through the radial pin, so that the base and the clamping cap can be effectively prevented from being loosened under the action of external force disturbance such as vibration in the machining process, and the clamping is more reliable.
The threaded connection between the base and the clamping cap preferably adopts a limiting threaded connection. The structure of the limiting threaded connection is specifically as follows: be equipped with radial concave point 213 in the external screw thread region of work piece installation department, be equipped with radial bump (not shown in the figure) on the internal thread region internal relative position of clamp cap, the in-process that the screw thread was screwed, the phenomenon takes place to interfere with the concave point in the bump embedding the angular limit function of screw thread is realized to the concave point, makes two pinhole alignment on work piece installation department and the clamp cap, the plug of the locating pin of being convenient for.
The depth of the concave point is about 0.2-0.3mm, and the periphery of the concave point is provided with rough edges.
During installation, a workpiece is firstly installed in the workpiece base installation hole in the base, then the clamping cap is screwed tightly on the base until a convex point arranged on the surface of an internal thread on the clamping cap is embedded into a concave point arranged on the surface of an external thread of the base, at the moment, the base is overlapped with the axis of a pin hole of the clamping cap, and finally the positioning pin is inserted into the two pin holes.
The utility model discloses can be used for the batch production of high accuracy, finding, help obviously improving production efficiency and machining precision.
