Description

Technical Field

[0001] The present application relates to the technical field of track segment detection, and in particular to a track segment drop detection mechanism and a detection method. Background Art

[0002] The drop of the track segments is a key indicator in the machining and assembly process. If the drop is too small, it will easily cause the front and rear track segments to "bite" after press-fitting, and the track assembly cannot rotate normally. If the drop is too large, it will make the front and rear track segments difficult or impossible to press-fit. When the chain is in use, particles are easy to enter the gap, squeezing the sealing ring, causing oil leakage, and affecting the quality of the track assembly.

[0003] The bulldozer track segment needs to be tested for consistency of drop after forging and before machining. Due to the multi-curved shape of the track segment, existing testing methods such as vernier calipers, height gauges, and three-coordinate measuring tools are difficult to measure. Summary of the invention

[0004] In view of the deficiencies in the prior art, one of the purposes of the present application is to provide a track segment drop detection mechanism and a detection method, which have the advantage of being easy to detect the track segment.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0006] A chain track segment drop detection mechanism comprises a support seat, on which a fixing device and a positioning device are provided. The positioning device is used to position one end of the chain track segment, and the fixing device is used to fix the other end of the chain track segment. The positioning device comprises a positioning rod, and the support seat is provided with a positioning hole. The positioning rod is used to be inserted into the positioning hole.

[0007] By adopting the above technical solution, during use, the chain track section is supported by the positioning rod and the fixing device, so that the chain track section is suspended in the air, thereby facilitating the operator to detect the chain track section.

[0008] In a preferred example, the present application can be further configured as follows: the fixing device includes a clamping arm, a fixing arm and a fixing rod, the fixing rod is fixedly connected to the support seat, the clamping arm and the fixing rod are hinged, and the fixing arm is installed on the fixing rod to cooperate with one end of the clamping arm to clamp one end of the chain track segment.

[0009] By adopting the above technical solution, during use, since the clamping arm and the fixed rod are hinged, when one end of the chain track segment is placed on the clamping arm, the other end of the clamping arm is subjected to force, which can make one end of the supporting chain track segment rise until the chain track segment contacts the fixed rod, thereby realizing the positioning of the chain track segment.

[0010] In a preferred example, the present application can be further configured as follows: an adjusting member is provided on the fixed arm, the adjusting member can move relative to the fixed arm, and the adjusting member is used to cooperate with one end of the clamping arm to clamp one end of the chain track segment.

[0011] By adopting the above technical solution and the existence of the adjusting member, the purpose of fixing the chain track links of different specifications can be achieved by adjusting the relative position between the adjusting member and the fixed arm.

[0012] In a preferred example, the present application can be further configured as follows: the fixing device also includes a pressing member, the pressing member is arranged at an end of the clamping arm away from the fixing rod, and the relative position between the pressing member and the clamping arm is adjustable.

[0013] By adopting the above technical solution, the existence of the pressing member can apply pressure to the clamping arm, so that the other end of the clamping arm is tilted, thereby achieving a clamping effect on the track link.

[0014] The present application also discloses a method for detecting the drop of a track segment: it includes the above-mentioned detection mechanism, and also includes the following steps: a positioning step, inserting a positioning rod into a corresponding positioning hole according to the specifications of the track segment, a placement step, supporting one end of the track segment by the positioning rod and the other end by a fixing device, and a measuring step, detecting the drop of the track segment.

[0015] In a preferred example, the present application can be further configured as follows: in the placing step, a clamping step is included, in which one end of the track link is placed between the clamping arm and the fixed arm, and pressure is applied to the other end of the clamping arm to clamp the track link.

[0016] In a preferred example, the present application can be further configured as follows: before the placing step, an adjustment step is also included to adjust the relative positions of the adjusting member and the fixed arm according to the specifications of the chain track segment.

[0017] In a preferred example, the present application can be further configured as follows: it also includes a material picking step, and after the detection is completed, the relative positions of the pressing member and the clamping arm are adjusted so that the clamping arm cancels the clamping of the chain track link.
