Description

Technical Field

[0001] The utility model relates to the technical field of spindle detection, in particular to a spindle machining omission detection device. Background Art

[0002] The spindle is the shaft that receives power from the engine or motor and transmits it to other parts. After the spindle is processed, it needs to be tested by testing equipment for parameters such as diameter, length, angle, roundness and length. This can ensure the quality of the spindle and detect whether there is a spindle that has been missed. When testing the spindle, it is necessary to clamp the spindle with a clamping mechanism and then drive the spindle to rotate. At this time, it can be tested by a detector. However, during the clamping process, two conical clamps are needed to drill the holes at both ends of the spindle. In order to clamp the spindle, it is necessary to spend time to align the pointed cone-shaped clamp with the hole at the end of the spindle during the placement process. In the process of clamping the spindle, most of the detection devices in the prior art need to accurately align the pointed cone-shaped clamp with the hole at the end of the spindle. Therefore, there may be alignment difficulties during the clamping process, and it takes more time and effort to ensure the accurate docking of the clamp with the hole. If the clamp is not completely aligned with the hole at the end of the spindle, it will lead to unstable clamping, which will cause the spindle to shake or deviate during rotation, thereby affecting the accuracy of detection.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention.

[0027] Example 1

[0028] Reference Figure 1-Figure 5 , which is the first embodiment of the utility model, and provides a spindle machining omission detection device. The spindle machining omission detection device includes a main body component 100 and a positioning component 200, and the spindle can be quickly clamped by the positioning component 200.

[0029] Specifically, the main component 100 includes a body 101, a detection mechanism 102, an upper clamp 103, a rotating shaft 104 and a lower clamp 105. The detection mechanism 102 is located in the body 101, the upper clamp 103 is arranged on the inner side of the body 101, the rotating shaft 104 is located in the body 101, and the lower clamp 105 is fixed to the top of the rotating shaft 104.

[0030] The detection mechanism 102 can move up and down in the body 101. The ends of the lower clamp 105 and the upper clamp 103 are both cone-shaped. By clamping the ends of the main shaft, the main shaft can be completely exposed to the outside, and then the main shaft can be comprehensively detected. The rotating shaft 104 is used to drive the lower clamp 105 to rotate, and the upper clamp 103 can be telescopically moved up and down. The main shaft is placed between the lower clamp 105 and the upper clamp 103, and then the detection mechanism 102 is used to detect the parameters such as the diameter, length, angle, roundness and length of the main shaft, so as to ensure the quality of the main shaft. At the same time, it can detect whether there is a main shaft that has been missed for processing. This is a prior art and this solution will not be elaborated in detail. Those skilled in the art can clearly understand the working principle.

[0031] Specifically, the positioning assembly 200 is disposed outside the lower clamp 105, and includes a positioning member 201, a rotating member 202 and a trigger member 203. The positioning member 201 is located outside the lower clamp 105, the rotating member 202 is disposed outside the positioning member 201, and the trigger member 203 is located inside the rotating member 202.

[0032] By setting the positioning piece 201, the spindle to be inspected is positioned so that when the spindle is placed on the top of the lower fixture 105, the end of the lower fixture 105 can be directly aligned with the hole at the bottom of the spindle, and the spindle can be in a vertical state. At this time, the upper fixture 103 can be directly aligned with the hole at the top of the spindle when moving downward, so as to facilitate the clamping of the spindle and avoid unstable clamping of the spindle, which may cause the spindle to shake or deviate during rotation.

[0033] When the main shaft rotates, the trigger member 203 drives the rotating member 202 to rotate, and the rotating member 202 drives the positioning member 201 to move downward, so that the positioning member 201 can be separated from the outside of the main shaft and the main shaft is completely exposed to the outside, thereby avoiding obstruction of the main shaft during the detection process, thereby affecting the accuracy of the main shaft detection.

[0034] Example 2

[0035] Reference Figure 1-Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0036] Specifically, the positioning member 201 includes a positioning sleeve 201 a , and the positioning sleeve 201 a is sleeved on the outer side of the lower fixture 105 .

[0037] The positioning sleeve 201a is movably connected to the outer side of the lower clamp 105 and is higher than the top of the lower clamp 105. When the spindle needs to be placed on the top of the lower clamp 105, it only needs to be inserted into the positioning sleeve 201a and positioned by the positioning sleeve 201a so that it is in a vertical state. In this way, the end of the lower clamp 105 can be directly aligned with the hole at the bottom end of the spindle. At this time, the upper clamp 103 can be directly aligned with the hole at the top end of the spindle when moving downward, so that the spindle can be clamped easily and unstable clamping of the spindle can be avoided, which may cause the spindle to shake or deviate during rotation.

[0038] Specifically, the positioning member 201 further includes a positioning plate 201b and a positioning column 201c. One side of the positioning plate 201b is fixed to the positioning sleeve 201a, and the positioning column 201c is inserted into the positioning plate 201b.

[0039] The bottom end of the positioning column 201c is fixed to the inner platform of the body 101, and is used to position the positioning sleeve 201a through the cooperation of the positioning plate 201b and the positioning column 201c to prevent the positioning sleeve 201a from rotating when moving up and down.

[0040] Specifically, the rotating member 202 includes a rotating frame 202a, a rotating sleeve 202b and a fixed shaft 202c. The rotating frame 202a is located outside the rotating shaft 104, the rotating sleeve 202b is fixed to the top of the rotating frame 202a, and the fixed shaft 202c is arranged on the inner side of the rotating frame 202a. A spiral groove 201a-1 is opened on the positioning sleeve 201a, and the fixed shaft 202c slides in the spiral groove 201a-1.

[0041] The rotating frame 202a is rotatably connected to the inner platform of the body 101 through a bearing. When the rotating frame 202a rotates, it will drive the rotating sleeve 202b to rotate, and the rotating sleeve 202b will drive the fixed shaft 202c to slide in the spiral groove 201a-1. The cooperation between the two will drive the positioning sleeve 201a to move downward, so that the positioning sleeve 201a can be separated from the outer side of the main shaft and the main shaft can be completely exposed to the outside.

[0042] Specifically, the rotating member 202 further includes a first spring 202d, and two ends of the first spring 202d are respectively fixed to the inner wall of the positioning sleeve 201a and the rotating sleeve 202b.

[0043] When the rotating sleeve 202b stops rotating, the first spring 202d applies an upward thrust to the positioning sleeve 201a, so that the positioning sleeve 201a moves upward to the initial position, thereby positioning the next spindle to be inspected.

[0044] Specifically, the rotating member 202 also includes an annular block 202e and a positioning shaft 202f. An annular groove 202b-1 is opened in the rotating sleeve 202b. The annular block 202e slides in the annular groove 202b-1. The positioning shaft 202f is located in the annular block 202e. A positioning hole 202b-2 is opened in the rotating sleeve 202b. The positioning shaft 202f is engaged with the positioning hole 202b-2.

[0045] There are multiple positioning holes 202b-2, which are evenly distributed in a ring shape on the inner bottom wall of the annular groove 202b-1. The bottom end of the positioning shaft 202f is arc-shaped. One end of the fixed shaft 202c is fixed to the inner wall of the annular block 202e. A chamber is opened in the annular block 202e, and the positioning shaft 202f is located in the chamber.

[0046] When the positioning shaft 202f is engaged with the positioning hole 202b-2, the annular block 202e is connected to the rotating sleeve 202b through the cooperation of the two, so that when the rotating sleeve 202b rotates, it can drive the annular block 202e to rotate, so that the annular block 202e can drive the fixed shaft 202c to slide in the spiral groove 201a-1. When the fixed shaft 202c contacts the end of the inner wall of the spiral groove 201a-1 and cannot move further, the positioning shaft 202f will be separated from the positioning hole 202b-2, and the annular block 202e will stop rotating. By setting a plurality of positioning holes 202b-2, the positioning shaft 202f can be engaged with the positioning hole 202b-2 at any position.

[0047] Example 3

[0048] Reference Figure 1-Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0049] Specifically, the rotating member 202 further includes a second spring 202g, and one end of the second spring 202g is fixed to the positioning shaft 202f.

[0050] The second spring 202g applies a thrust to the positioning shaft 202f, so that the positioning shaft 202f and the positioning hole 202b-2 are more tightly engaged.

[0051] Specifically, the trigger member 203 includes a fixing sleeve 203a and a limiting column 203b. One end of the fixing sleeve 203a is fixed to the rotating shaft 104. The limiting column 203b is located in the fixing sleeve 203a. A limiting hole 202a-1 corresponding to the limiting column 203b is opened in the rotating frame 202a.

[0052] There are multiple limiting holes 202a-1, which are evenly distributed in a ring shape on the inner side of the rotating frame 202a. When the rotating shaft 104 rotates, it will drive the fixed sleeve 203a to rotate. At this time, the limiting column 203b will move outward and engage with the limiting hole 202a-1. At this time, the fixing sleeve 203a is connected to the rotating frame 202a through the two, so that the fixing sleeve 203a drives the rotating frame 202a to rotate.

[0053] Specifically, the trigger member 203 further includes a sensing ball 203c and a fixing plate 203d. The sensing ball 203c is located in the fixing sleeve 203a, and the fixing plate 203d is fixed to one end of the limiting column 203b.

[0054] When the fixing sleeve 203a rotates, the centrifugal force generated will cause the sensing ball 203c to move outward from the fixing sleeve 203a, and the sensing ball 203c will push the fixing plate 203d and the limiting column 203b to move, so that the limiting column 203b can be engaged with the limiting hole 202a-1.

[0055] Specifically, the trigger member 203 further includes a third spring 203e, and two ends of the third spring 203e are respectively fixed to the fixing plate 203d and the inner wall of the fixing sleeve 203a.

[0056] When the fixing sleeve 203a stops rotating, the third spring 203e applies a thrust to the fixing plate 203d, and the fixing plate 203d drives the limiting column 203b to move, so that the limiting hole 202a-1 of the limiting column 203b is separated.

[0057] During use, when inspecting the spindle, the upper clamp 103 is moved upward and then inserted into the positioning sleeve 201a. The positioning sleeve 201a is used to position it so that it is in a vertical state, so that the end of the lower clamp 105 can be directly aligned with the hole at the bottom end of the spindle. At this time, when the upper clamp 103 moves downward, it can be directly aligned with the hole at the top end of the spindle, which makes it easier to clamp the spindle and avoids unstable clamping of the spindle, which may cause the spindle to shake or deviate during rotation.

[0058] When the rotating shaft 104 rotates, it will drive the fixed sleeve 203a to rotate. When the fixed sleeve 203a rotates, the centrifugal force generated will cause the sensing ball 203c to move to the outside of the fixed sleeve 203a, and the sensing ball 203c will push the fixed plate 203d and the limiting column 203b to move, so that the limiting column 203b can be engaged with the limiting hole 202a-1, and the fixed sleeve 203a is connected to the rotating frame 202a through the two, so that the fixed sleeve 203a drives the rotating frame 202a to rotate.

[0059] When the rotating frame 202a rotates, it will drive the rotating sleeve 202b to rotate, and the rotating sleeve 202b will drive the fixed shaft 202c to slide in the spiral groove 201a-1. The cooperation between the two will drive the positioning sleeve 201a to move downward, so that the positioning sleeve 201a can be separated from the outside of the main shaft and the main shaft is completely exposed to the outside, thereby avoiding the positioning sleeve 201a from blocking the main shaft and affecting the accuracy of the main shaft detection.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
