Description

Technical Field

[0001] The utility model relates to the field of eccentric shaft detection, in particular to a quick detection fixture for position detection. Background Art

[0002] Eccentric shaft products are a common mechanical part. In mechanical transmission, rotary motion is converted into reciprocating linear motion or reciprocating linear motion is converted into rotary motion. The eccentric shaft is generally fixed on the rotating shaft of the motor through an eccentric hole. When the motor starts, it performs cam motion. Therefore, it is widely used in automobiles, engines, pumps, etc. The processing of this product is also a common mechanical processing. With the development of production technology, the requirements for product precision are getting higher and higher. There are position requirements for the structural elements of important parts of eccentric shaft products. At present, most of the position is measured by three-coordinate detection. When measuring, the benchmark is taken first. It takes a long time to take the benchmark point. It takes several minutes to measure the position of one place. The detection time is long. Due to the limitation of the detection equipment, it can only be inspected for the first time and sampled, and not all inspections. There are certain quality risks. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", and "connected" should be understood in a broad sense; for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, or an electrical connection, a direct connection, or an indirect connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] See also Figure 1-5 A quick inspection tool for position detection includes a spline gauge base 1 and a caliper 2. A caliper placement groove 6 is provided at the central position of the top of the spline gauge base 1. A caliper 2 is movably provided on the caliper placement groove 6. When working, the central shaft end, the spline on the central shaft end and the intermediate shaft wheel of the eccentric shaft 3 to be measured are inspected through the spline gauge base 1. The eccentric outer circle end of one side of the eccentric shaft 3 to be measured is conveniently and promptly inspected through the caliper 2, thereby improving the detection effect and efficiency, increasing safety and facilitating the use of the device.

[0022] A central through hole 4 is provided at the center position inside the spline gauge base 1, and a spline gauge 5 is provided on the central through hole 4. An eccentric shaft wheel placement groove 7 is provided inside the spline gauge base 1, and the eccentric shaft wheel placement groove 7 is coaxially connected with the central through hole 4. When working, the central shaft end of the eccentric shaft 3 to be tested is inserted into the spline gauge base 1. When the central through hole 4, the spline gauge 5, the central shaft end of the eccentric shaft 3 to be tested, and the splines on the central shaft end are all consistent, the central shaft end of the eccentric shaft 3 to be tested is qualified; at the same time, the eccentric shaft wheel placement groove 7 and the intermediate shaft wheel of the eccentric shaft 3 to be tested are detected. Whether they match, if they match, the intermediate shaft wheel of the eccentric shaft 3 to be tested meets the requirements; place the caliper 2 on the top of the spline gauge base 1, insert the eccentric shaft end on one side of the eccentric shaft 3 to be tested into the caliper 2, slide the caliper 2 back and forth on the top of the spline gauge base 1 to detect whether the eccentric shaft end of the eccentric shaft 3 to be tested meets the requirements, if there is no obstruction when sliding, it means that the eccentric shaft end of the eccentric shaft 3 to be tested is qualified; if the tests at three places are all qualified, it means that the part of the eccentric shaft 3 to be tested is qualified, if there is one unqualified side, it means that the part of the eccentric shaft 3 to be tested is unqualified.

[0023] The eccentric shaft wheel placement groove 7 is arranged close to the caliper placement groove 6 to facilitate subsequent detection and ensure safety.

[0024] The shape of the caliper 2 is a rounded rectangle, and a through slot is provided in the middle of the caliper 2, and the width of the through slot is equal to the outer diameter of the eccentric shaft end of the eccentric shaft 3 to be measured.

[0025] There are three groups of spline gauges 5, and the splines on the eccentric shaft 3 to be tested are tested by the three groups of spline gauges 5, so as to improve the effect and efficiency of the test, ensure safety, and facilitate the use of the device.

[0026] The utility model first designs a through gauge based on the keyways at three locations of the eccentric shaft, and processes an end face groove on one side of the through gauge axis, and strictly controls the relative positions of the through gauge and the end face groove; secondly, designs a caliper gauge based on the eccentric outer diameter of the eccentric shaft, and simultaneously matches the side distances of two planes on the periphery of the caliper gauge with the end face groove of the keyway through gauge; finally, aligns the keyways at three locations of the eccentric shaft with the key teeth of the through gauge, and after inserting, assembles the caliper gauge along the end face groove of the through gauge; if the caliper gauge can be inserted and can freely move along the end face groove (to control the clearance), it is qualified, otherwise it is unqualified.

[0027] The utility model is simple and convenient to use, can monitor the online products in real time and can easily realize full inspection to ensure product quality. The eccentric shaft has a special structure, with 3 normal ground outer circles and 1 eccentric ground outer circle. Among the 3 normal ground outer circles, the largest outer circle has 3 equally divided keyways. The keyway and the large ground outer circle, the smallest ground outer circle and the eccentric ground outer circle have a position accuracy requirement of 0.1. During processing, only the first piece can be subjected to three-coordinate detection and process (4 hours) sampling inspection. During measurement, it cannot be measured in time and the measurement time is long, which is time-consuming and labor-intensive, and has a serious impact on processing. If the spline gauge base can be smoothly inserted into the eccentric ground outer circle and slide freely along the end face groove, the position accuracy is qualified. If the spline gauge base cannot be smoothly inserted into the eccentric ground outer circle, the position accuracy is out of tolerance. The inspection using this inspection fixture is convenient, fast, efficient, and can realize full inspection. The quality inspection results are verified by three-coordinate verification, meet the requirements of the drawings, and are qualified. The quick inspection fixture can be used online with confidence.
