Description

Technical Field

[0001] The utility model relates to the technical field of symmetry detection devices, in particular to a symmetry detection device for a pickaxe drill sleeve special-shaped part. Background Art

[0002] Symmetry mainly controls the geometric tolerance of the symmetry error of surface features. The tolerance zone is a symmetry plane centered on a reference plane or line. The spacing of the symmetry planes is the size of the tolerance zone. The midpoint of the surface feature controlled by symmetry must fall within the tolerance zone, that is, it must fall within the spacing of the symmetric planes. Symmetry is mainly applied to features that are symmetrical to the center, and the detection of the keyway symmetry of the pick and drill sleeve special-shaped parts requires the use of a keyway symmetry gauge.

[0003] When the existing symmetry detection device is used, the corresponding workpiece keyway fixing frame is customized according to the size of the workpiece keyway, the workpiece keyway of the pick drill sleeve special-shaped part is engaged with the workpiece keyway fixing frame, and the workpiece keyway fixing frame with the pick drill sleeve special-shaped part is placed in the gauge slot, and the probe position is manually adjusted obliquely so that the probe of the test caliper is located on one side of the pick drill sleeve special-shaped part, and the data on one side of the pick drill sleeve special-shaped part is tested by the test caliper, and then the workpiece keyway fixing frame with the pick drill sleeve special-shaped part is rotated 180° and placed in the gauge slot, and the data on the other side of the pick drill sleeve special-shaped part is tested by the test caliper, and the two sets of data are compared to obtain the contrast data of the workpiece keyway of the pick drill sleeve special-shaped part. Since the contrast testing device needs to manually adjust the probe position and can only be adjusted obliquely, the test caliper has a small application range and is difficult to detect the workpiece keyways in pick drill sleeve special-shaped parts of different diameters. Summary of the invention

[0004] The utility model aims to provide a device for detecting symmetry of special-shaped parts of a pickaxe drill sleeve, so as to solve the problem that the device for detecting symmetry of special-shaped parts of a pickaxe drill sleeve on the market currently has a small application range as proposed by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for detecting the symmetry of pick drill sleeve special-shaped parts, comprising a base, a fixing plate and a support frame, a fixing plate is welded to the top end of one side of the base, and a support frame is welded to the outer side of the base.

[0006] Preferably, an axle seat is welded to the inner wall of the top of the fixed plate, the inner side of the axle seat is connected to an electric push rod via a rotating shaft, the output end of the electric push rod is connected to a connecting frame via a rotating shaft, and the end of the connecting frame away from the electric push rod is connected to a connecting seat via a rotating shaft.

[0007] Preferably, a gauge slot frame is welded to one end of the connecting seat away from the connecting frame, a sliding block is welded to the bottom end of the gauge slot frame, and a guide slot is provided at the top end of the base located on the outside of the sliding block.

[0008] Preferably, a scale is provided inside the base.

[0009] Preferably, a lifting frame is sleeved on the outer side of the support frame, a test caliper is installed on the top of the lifting frame, a one-way threaded rod extending to the outside of the bottom end is arranged on the inner side of the lifting frame, and the one-way threaded rod passes through the interior of the support frame, and a rotating block is welded to the bottom end of the one-way threaded rod.

[0010] Preferably, a workpiece keyway fixing frame is provided on the inner side of the gauge slot frame, two groups of movable plates extending to the outer side of the top end are provided on the inner side of the workpiece keyway fixing frame, anti-slip pads are provided on the outer sides of the two groups of movable plates, and a bidirectional threaded rod passing through the two groups of movable plates is provided inside the workpiece keyway fixing frame, and a hexagonal groove is provided at one end of the bidirectional threaded rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the symmetry detection device needs to detect pick drill sleeve special-shaped parts with different diameters, the output end of the electric push rod pushes the top of the connecting frame to descend, so that the bottom end of the connecting frame pushes the connecting seat, the gauge slot frame and the sliding block to move through the rotating shaft. The movement of the gauge slot frame drives the workpiece keyway fixing frame and the pick drill sleeve special-shaped part to move, so that the position of the workpiece keyway fixing frame of the symmetry detection device can be automatically adjusted, which is convenient for the symmetry detection device to detect pick drill sleeve special-shaped parts with different diameters, thereby expanding the application scope of the symmetry detection device.

[0013] 2. When the symmetry detection device needs to use a workpiece keyway fixing frame to fix the pick drill sleeve special-shaped part, two sets of movable plates and anti-skid gaskets are inserted into the workpiece keyway of the pick drill sleeve special-shaped part, and an external hexagonal wrench is used to drive the hexagonal slot and the bidirectional threaded rod to rotate forward. The forward rotation of the bidirectional threaded rod drives the two sets of movable plates to move, and the distance between the two sets of movable plates gradually increases. The two sets of movable plates push the two sets of anti-skid gaskets to support the inside of the workpiece keyway of the pick drill sleeve special-shaped part. The movable plates and anti-skid gaskets limit the workpiece keyway of the pick drill sleeve special-shaped part, and the pick drill sleeve special-shaped part is fixed to the top of the workpiece keyway fixing frame, so that the workpiece keyway fixing frame of the symmetry detection device does not need to be customized according to different pick drill sleeve special-shaped parts, which provides convenience for operators and reduces material loss and waste.
