Abstract
The utility model relates to a tooling for detecting the dimension of a holder, especially relates to a detection tooling used for the internal and external diameters of an engineering plastic holder. The detection tooling used for the internal and external diameters of the engineering plastic holder belongs to the plastic product detection device field, and is characterized in that two holder positioning grooves and claw positioning grooves are arranged in the contacted end face peripheral direction of a positioning table and the holder, and the claw positioning grooves are evenly distributed on a circumference between the two holder positioning grooves; a caliper contact surface is arranged on the contacted end face of the positioning table and a main scale of the caliper, and the two sides of the positioning table are equipped with holder contact surfaces. By using the detection tooling, the measurement positions of the internal and external diameter dimensions of the holder are positioned, the problem is eliminated that an inspector does not control the measurement positions accurately, so that the detection result accuracy is very low, at the same time, the parallelism of the main scale of the caliper and an end ring of the holder is guaranteed, and a measurement deviation caused by the parallelism is eliminated.
Description
Technical field
The utility model relates to a kind of detection retainer size frock, specifically relates to the detection frock that a kind of cylinder roller bearing is used the engineering plastics cage inside/outside diameter size, and it belongs to the pick-up unit field of plastic products.
Background technology
Plastic products are after the demoulding is cooling, and meeting generation drawdown deformation in various degree is also like this for engineering plastics cage.Because engineering plastics cage is the very high plastic products of quality requirements, so the degree of accuracy of the testing result of its size is very crucial.After the cooling contraction of the demoulding, each position inside/outside diameter size on the circumferencial direction in each waits subdivision is neither identical with engineering plastics cage for cylinder roller bearing; Each position inside/outside diameter size on frame end circle axial direction is not identical yet keeping.Therefore, want to measure numerical value accurately, very large difficulty is arranged.At present, the inside/outside diameter size of retainer detects and all directly measures with slide calliper rule, and the measuring position is difficult to control, and its testing result accuracy is very low.In addition, because main scale and the depth of parallelism that keeps the frame end circle of slide calliper rule are only controlled by both hands are very difficult, therefore testing result is also had a significant impact.
Summary of the invention
Problem in view of the prior art existence, the purpose of this utility model is that a kind of detection frock for the engineering plastics cage internal-and external diameter will be provided, solving because the measuring position is difficult to control, main scale and the depth of parallelism that keeps the frame end circle of slide calliper rule are difficult to control, and the very low problem of size detection result precision that produces.
For achieving the above object, the technical scheme that the utility model adopts is a kind of detection frock for the engineering plastics cage internal-and external diameter, it is characterized in that the end face circumferencial direction that contacts with retainer at positioning table is provided with retainer locating slot and claw locating slot, described retainer locating slot is two; Described claw locating slot is evenly distributed on two circumference between the retainer locating slot; Be provided with the slide calliper rule surface of contact on positioning table and end face that the slide calliper rule main scale contacts, be provided with the retainer surface of contact in the both sides of positioning table.
When measuring the retainer internal-and external diameter, positioning table lies in and keeps on the frame end circle, the retainer surface of contact contacts with keeping the frame end circle, the retainer locating slot coordinates with retainer window beam, with product orientation, simultaneously the measuring position is located, the slide calliper rule main scale lies on positioning table, contact with the slide calliper rule surface of contact, claw enters the claw locating slot, draws to push away vernier and measure.
The utility model has the advantage of: by detecting the use of frock, the measuring position of the inside/outside diameter size of retainer is located, and eliminates the overlooker and controls the inaccurate very low problem of testing result accuracy that produces because of the measuring position.Simultaneously, detect frock and guaranteed slide calliper rule main scale and the depth of parallelism that keeps the frame end circle, eliminate therefore and the measured deviation that produces.

Embodiment
Should to detect frock with the engineering plastics cage inside/outside diameter size for cylinder roller bearing in order further understanding, 1-4 to be elaborated by reference to the accompanying drawings:
A kind of detection frock for the engineering plastics cage internal-and external diameter, the end face circumferencial direction that contacts with retainer at positioning table is provided with retainer locating slot 1 and claw locating slot 2, and described retainer locating slot 1 is two; Described claw locating slot 2 is evenly distributed on two circumference between retainer locating slot 1; Be provided with slide calliper rule surface of contact 3 on positioning table and end face that the slide calliper rule main scale contacts, be provided with retainer surface of contact 4 in the both sides of positioning table.
When measuring the retainer internal-and external diameter, positioning table lies in and keeps on the frame end circle, retainer surface of contact 4 contacts with keeping the frame end circle, retainer locating slot 1 coordinates with retainer window beam, with product orientation, simultaneously the measuring position is located, the slide calliper rule main scale lies on positioning table, contact with slide calliper rule surface of contact 3, claw enters claw locating slot 2, draws to push away vernier and measure.
