At present, in order to ensure that the product quality is completely qualified, a high-precision measuring instrument three-coordinate detector is adopted for detection, the equipment can realize detection aiming at the phi 19.981 size, but the product cost is increased due to the adoption of three-coordinate detection, and a field assembly line cannot be configured with the three-coordinate detection equipment for flow line operation, so that the product processing efficiency is low, and the production line operation is not easy to realize.
The utility model has the following contents:
the utility model discloses be exactly in order to overcome not enough among the prior art, provide a detection device of balancing weight.
The application provides the following technical scheme:
the utility model provides a detection apparatus for balancing weight, it includes the workstation, sets up bracing piece, its characterized in that on the workstation: be equipped with the portion of bending in bracing piece one side, be connected with the bottom plate in the portion of bending, be connected with the fixed plate on the bottom plate, be connected with a set of gauge stand and a set of fixing base on the fixed plate, correspond the distribution at every gauge stand and every fixing base, equal swing joint has the detection piece on every fixing base, all be connected with the amesdial on every gauge stand, the tip of the pilot pin of amesdial passes the fixing base and detects the piece contact, the positioning seat that is connected with on the fixed plate, be connected with the correction block on the positioning seat, appearance and qualified balancing weight size at the correction block are the same, it corresponds the cooperation with correction block one end tip to detect the piece.
On the basis of the technical scheme, the following further technical scheme can be provided:
the bending included angle between the bending part and the supporting seat is an obtuse angle.
Positioning holes are correspondingly distributed on the positioning seat and the correction block, and positioning pins which are correspondingly matched are arranged in the positioning holes.
The three gauge seats are distributed in three directions of one end of the correcting block, so that the dial gauges on the gauge seats can detect one end of the correcting block from the three directions, and detection points in two directions are symmetrically distributed.
The detection device is characterized in that the fixed seat is connected with a pair of guide posts, the detection block is arranged on the guide posts in a penetrating mode and can move along the guide posts, and springs correspondingly matched with the detection block and the fixed seat are arranged on the guide posts in a penetrating mode.
Utility model advantage:
the utility model discloses simple structure, convenient to use, detection accuracy have improved the efficiency of production line, have reduced product cost.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a front view of the present invention.
The specific implementation mode is as follows:
as shown in fig. 1 and 2, a detection device for a balancing weight comprises a workbench 1, wherein support rods 2 which are vertically distributed are fixedly mounted on the workbench 1, a bending part 2a extends from one side of each support rod 2, and an acute included angle is formed between an extension line of the bending part 2a and the workbench 1. A set of height-adjusting bolts 1a is attached to the table 1.
The bending part 2a is connected with a bottom plate 3, and one end of the bottom plate 3 is lapped on the workbench 1 and forms an acute included angle with the workbench. Be connected with fixed plate 8 on bottom plate 3, be connected with a set of table seat 4 and a set of fixing base 9 on fixed plate 8, correspond the distribution at every table seat 4 and every fixing base 9. The fixing plate 8 is also connected with a positioning seat 6.
A pair of guide posts 9c are fixedly connected to the upper end of each fixed seat 9, a movable T-shaped detection block 9a is arranged on each guide post 9c in a penetrating manner, and a spring 9b is further sleeved on each guide post 9c between the fixed seat 9 and the detection block 9 a. A limit cap head 9d correspondingly matched with the detection block 9a extends from one end of each guide post 9 c.
Each gauge stand 4 is connected with a dial indicator 5, and the end part of a positioning needle 5a of the dial indicator 5 penetrates through the fixed seat 9 to be in contact with the detection block 9a so as to detect the condition that the detection block 9a moves on the guide post 9 c. A correction block 7 with the same shape and the same size as the qualified balancing weight is arranged. Positioning holes 7a which are distributed correspondingly are arranged on the positioning seat 6 and the correction block 7, and positioning pins 7b which are matched correspondingly are arranged in the positioning holes 7 a.
The three gauge seats 4 are distributed in three directions of one end of the correcting block 7, so that the three dial gauges 5 can detect one end of the correcting block 7 from three directions, wherein the two direction detection points are symmetrically distributed. So as to obtain accurate phi size data of the excircle three-coordinate detection of the end part and record the phi size data.
The using process comprises the following steps:
the manual promotion of staff detects a section distance of backward movement, then will detect on the balancing weight is placed the positioning seat and then fix the two through the locating pin, it resets under the effect of spring to detect the piece simultaneously, thereby three direction contact balancing weight one end tip (this end is the installation end tip of balancing weight and rotor installation in the subsequent handling), then obtain the excircle three-dimensional coordinate of this tip simultaneously and detect accurate phi dimensional data, then with preceding correction block one end tip detect the data record and compare, if in the tolerance range, then this balancing weight is the qualified piece.
