Description
Technical Field
The invention belongs to the technical field of belt pulley detection, and particularly relates to a high-precision belt pulley runout detection tool.
Background
After key processes of the existing belt pulley, such as stamping, spinning and other processes, the contact surface part of the belt pulley and the belt has a jumping size requirement relative to the inner hole of the bearing, and the detection reference of the belt pulley is the central axis of the bearing. When the jumping size is measured conventionally, the measuring can be completed by using the taper core rod to be in contact fit with the taper line of the bearing hole and combining with a jumping measuring instrument with larger occupied area. Firstly, the measurement adaptability is relatively low due to high requirement on space occupation, namely the device cannot be used in a production field with small space; secondly, a belt pulley bearing hole reference shaft is simulated through taper fit, the reference is greatly influenced by the taper size of the taper core rod and clamping, the repeatability of a jumping result is poor, when the dimensional tolerance of an inner hole of the belt pulley is large, the measurement accuracy can be guaranteed only by matching the taper core rods with different specifications, and the checking fixture is high in cost, management cost and detection cost.

The invention has the advantages that:
1) the workpiece mounting block is rotatably mounted on the mounting seat, and during measurement, the inner wall of a bearing hole of a workpiece is sleeved on the workpiece mounting block; then, screwing the sleeve locking part to effectively enable the rubber pressing sleeve to move inwards so as to form axial compression on the expansion silica gel ring, and along with the axial compression of the expansion silica gel ring, the radial direction of the expansion silica gel ring can form adaptive outward convex deformation, so that the abutting ball positioned at the bottom of the fixing hole is effectively driven to move upwards in an inclined manner, the abutting ball positioned at the upper part of the fixing hole is further driven to vertically move upwards and abut against the inner wall of the bearing hole of the workpiece, and the workpiece is effectively fixed; then, a measuring head of the dial indicator is abutted against the outer wall of the workpiece, the workpiece is driven to rotate through the rotation of the workpiece mounting block, and the jumping size of the workpiece can be measured through the dial indicator. The device has the advantages of simple structure, small occupied space, convenience in measurement operation, high measurement result precision, high detection efficiency and low detection cost.
2) In the process that the expansion silica gel ring generates radial deformation to push out the abutting piece, the two abutting balls in the same fixing hole abut against the expansion silica gel ring and the inner wall of the bearing hole of the workpiece respectively, and along with the increase of the abutting force, the expansion silica gel ring can form buffering deformation at the connecting part of the expansion silica gel ring and the abutting balls so as to prevent the excessive mechanical damage to the inner wall of the bearing hole of the workpiece caused by the overlarge abutting force.
And deformation through silica gel is in order to drive the butt joint ball and form radial butt joint to the work piece, and it can change the benchmark diameter in a relatively large scale, and the band pulley that can adapt to different dimensional tolerance measures and beats, and is more general in the broad adaptability, can effectively practice thrift the measurement cost.
3) According to the invention, each group of fixing holes are two, the bottoms of the fixing holes are arranged in an inward inclined manner, the upper parts of the fixing holes are arranged vertically upwards, two corresponding abutting balls are movably arranged in the fixing holes respectively, and the two abutting balls are arranged at the bottoms and the upper parts of the fixing holes respectively. Two fixing holes are formed in each group, so that double-point abutting support can be effectively formed on the same part of the workpiece, and the mounting stability of the workpiece is ensured. However, if the width of the silicone rubber ring is too large, the difficulty in controlling the radial expansion of the silicone rubber ring through axial compression is greatly increased, so that the width of the silicone rubber ring must be controlled within a small range, and accordingly, the distance between the abutting points of the abutting mechanism between the two fixing holes on the workpiece is naturally small, so that the installation stability caused by double-point abutting is limited.
Therefore, the bottom of the fixing hole is arranged in an inward inclined mode, the upper portion of the fixing hole is arranged in an upward vertical mode, and two abutting balls are arranged in the fixing hole. Therefore, the butt spacing of the butt joint balls in the same group of fixing holes can be effectively improved on the premise of not increasing the width of the expansion silica gel ring, so that the installation stability of the workpiece can be effectively improved on the premise of conveniently controlling the radial expansion of the silica gel.
4. In the axial compression (radial expansion) process of the expansion silica gel ring, the contact point between the expansion silica gel ring and the abutting ball changes, so that larger friction can be formed between the abutting ball and the expansion silica gel ring, and the expansion silica gel ring is easy to damage. According to the invention, through the matched arrangement of the two abutting balls, the inclined arrangement of the bottom of the fixing hole can be effectively adapted, and the rolling type abutting support with the expansion silica gel ring can be effectively realized, so that the damage of friction to the expansion silica gel ring is reduced, and the practical effect of the invention is effectively improved.
5. A corresponding O-shaped fixing ring is sleeved on the outer side of the workpiece mounting block, the O-shaped fixing ring is arranged between each two fixing holes and limits the abutting ball positioned at the upper part of the fixing hole, and the cross section of the O-shaped fixing ring is in an elliptical shape. Under the action of the O-shaped fixing ring, the abutting ball is effectively prevented from being separated from the fixing hole, so that the practical effect of the invention is effectively further ensured.
6. One end of the positioning sleeve, which is connected with the workpiece mounting block, is provided with a corresponding fixed convex edge, the fixed convex edge is positioned on the front side of the mounting vertical plate, the rear side of the workpiece mounting block is integrally formed and is outwards provided with a circle of corresponding mounting platform, and the rear end surface of the mounting platform abuts against the fixed convex edge of the positioning sleeve. The installation platform can effectively facilitate workpiece installation, and can effectively ensure the workpiece installation block and the fixed convex edge, namely effectively ensure the connection stability of the workpiece installation block and the positioning sleeve, and effectively ensure that the rotation of the workpiece installation block cannot form any interference with the installation vertical plate, thereby effectively further ensuring the practical effect of the invention.
In the measurement process of the jumping size, sometimes only the inner hole is used as a reference, but sometimes the drawing requires the inner hole to be used as a first reference, and meanwhile, the spoke face is used as a second reference, and the two modes are switched to control whether the cavity-shaped end face of the workpiece is attached to the mounting platform or not so as to realize conversion, so that the jumping size measuring method is convenient and fast.
