[0064] A vertical locking mechanism 3, the vertical locking mechanism 3 is fixedly arranged on the bottom plate, and the vertical locking mechanism 3 is suitable for vertically pressing the main shaft 11 in the main shaft assembly 1 to lock the main shaft assembly 1 in the vertical direction;

[0065] At least one swing arm detection mechanism 4, the swing arm detection mechanism 4 is fixedly arranged on the bottom plate, and the swing arm detection mechanism 4 is suitable for detecting the welding angle of the swing arm 12 on the main shaft 11 in the main shaft assembly 1;

[0066] At least one tooth plate detection mechanism 5 is fixedly arranged on the bottom plate, and the tooth plate detection mechanism 5 is suitable for detecting the welding angle of the tooth plate 13 on the main shaft 11 in the main shaft assembly 1.

[0067] Specifically, as an optional implementation in this embodiment, Figure 3As shown, the horizontal locking mechanism 2 includes

[0068] A horizontal fixing seat 21, which is fixedly arranged on the bottom plate;

[0069] A horizontal clamping block 22 is slidably arranged on a horizontal fixing seat 21, a V-shaped clamping opening is formed at the front end of the horizontal clamping block 22, a fixing pin is arranged at the rear end of the horizontal clamping block 22, a first tension spring 23 is arranged between the fixing pin and the horizontal fixing seat, and the first tension spring 23 is suitable for moving the horizontal clamping block 22 forward so that the V-shaped clamping opening abuts against the pin shaft 121 on the swing arm 12.

[0070] The installation position of the horizontal locking mechanism 2 on the base plate is determined by the position of the pin 121 on the swing arm 12 in the actually detected spindle assembly 1. The moving direction of the horizontal clamp 22 is perpendicular to the direction of the spindle 11. The pin 121 on the swing arm 12 is parallel to the spindle 11. The horizontal clamp 22 vertically abuts against the pin 121 of the swing arm 12, thereby achieving horizontal clamping of the spindle 11.

[0071] In the horizontal locking mechanism 2 , the clamping force of the horizontal clamping block 22 depends on the tension of the first tension spring 23 . In this embodiment, the number of the first tension springs 23 is two.

[0072] Specifically, as an optional implementation in this embodiment, Figure 4 As shown, the vertical locking mechanism 3 includes

[0073] A vertical fixing seat 31, which is fixed on the bottom plate;

[0074] A slide seat 32, wherein the lower end of the slide seat 32 is slidably matched with the vertical fixed seat 31, and the upper end of the slide seat 32 is hinged to the vertical pressing block 33;

[0075] A vertical pressing block 33, whose rear end is hinged with the slide seat 32, and a second tension spring 35 is connected between the vertical pressing block 33 and the slide seat 32, and the second tension spring 35 is suitable for driving the front end of the vertical pressing block 33 to vertically press the main shaft 11;

[0076] A lever 34, the lower end of which is hinged to the vertical fixing seat 31 and the sliding seat 32;

[0077] When the lever 34 swings back and forth, it drives the slider to move back and forth.

[0078] In this embodiment, a dovetail slot is formed at the upper end of the vertical fixing seat 31 , and a dovetail slider is formed at the lower end of the slide seat 32 . The dovetail slider cooperates with the dovetail slot to enable the slide seat 32 to slide on the vertical fixing seat 31 .

[0079] In this embodiment, there are two second tension springs 35 located on both sides of the slide seat 32 .

[0080] In this embodiment, the lever 34 is a U-shaped structure, and its two sides are respectively hinged to the vertical fixing seat 31 . Long grooves are also provided on both sides of the lever 34 , and the pins pass through the long grooves and are connected to the sliding seat 32 .

[0081] A handle is provided on the lever 34, and the handle drives the lever 34 to rotate forward and backward, so that the lever 34 drives the slide 32 to move forward and backward. When the lever 34 drives the slide 32 to move to the front position, the front end of the vertical pressure block 33 is located at the upper end of the main shaft 11. Since the vertical pressure block 33 is always subjected to the tension of the second tension spring 35, the front end of the vertical pressure block 33 can vertically press the main shaft 11.

[0082] In this embodiment, a pair of bearings for abutting the main shaft 11 are arranged at the front end of the vertical pressing block 33. The abutment of the main shaft 11 by the bearings can facilitate the circumferential position adjustment of the main shaft 11.

[0083] Specifically, as an optional implementation in this embodiment, Figure 5 Figure 6 As shown, the swing arm detection mechanism 4 includes

[0084] A first positioning block 41, which is fixedly arranged on the bottom plate;

[0085] A measuring block 42 is fixedly mounted on the upper end of the first positioning block 41, and a measuring hole 421 is formed on the measuring block 42 for cooperating with the pin 121 on the swing arm 12;

[0086] A pair of baffles 43 , both baffles 43 are fixed on the left and right sides of the first positioning block 41 , and the baffles 43 are suitable for limiting the measurement block 42 from moving out of the first positioning block 41 .

[0087] In this embodiment, the number of the swing arm detection mechanisms 4 is consistent with the number of the swing arms 12 on the main shaft 11 .

[0088] The installation position of the swing arm detection mechanism 4 on the base plate is selected according to the position of the pin 121 on the swing arm 12. The first positioning block 41 is locked on the base plate with bolts. The measuring block 42 slides on the first positioning block 41. The lower end of the measuring block 42 and the upper end of the first positioning block 41 form a guide rail and a guide groove respectively, so as to guide the measuring block 42 to translate. The measuring block 42 moves on the base plate along the length direction of the main shaft 11. If the installation position of the swing arm 12 on the main shaft 11 is qualified, then the pin 121 on the swing arm 12 can be inserted into the measuring hole 421 of the measuring block 42.

If it can pass easily, it means that the part size is qualified. If it cannot pass or passes with some difficulty during this process, it means that the corresponding size is unqualified.

[0090] Specifically, as an optional implementation in this embodiment, Figure 7 As shown, the tooth plate detection mechanism 5 includes

[0091] A second positioning block 51, wherein the second positioning block 51 is fixedly arranged on the bottom plate;

[0092] A first round bolt 52 is passed through the second positioning block 51. A first gauge 53 is disposed at the front end of the first round bolt 52. A spring 56 is disposed between the first round bolt 52 and the second positioning block 51. The first gauge 53 is suitable for detecting the tooth opening 131 on the tooth plate 13.

[0093] The second round bolt 54 is passed through the second positioning block 51 . A second gauge 55 is arranged at the front end of the second round bolt 54 . A spring 56 is arranged between the second round bolt 54 and the second positioning block 51 . The second gauge 55 is suitable for detecting the pin hole 132 on the tooth plate 13 .

[0094] The number of the toothed plate detection mechanisms 5 is consistent with the number of the toothed plates 13 on the main shaft 11 .

[0095] The installation position of the second positioning block 51 on the bottom plate is selected according to the position of the tooth plate 13 .

[0096] Working principle of the tooth plate detection mechanism 5: the first round bolt 52 and the second round bolt 54 are pushed open by the spring 56 when static, and the first gauge 53 and the second gauge 55 are both fitted on the first positioning block 41. When detection is required, the first round bolt 52 and the second round bolt 54 are manually pressed to make the first gauge 53 and the second gauge 55 respectively inserted into the tooth mouth 131 and the pin hole 132 on the tooth plate 13. If both gauges can be inserted, it means that the installation position of the tooth plate 13 on the main shaft 11 is qualified, otherwise it means that the installation of the tooth plate 13 is unqualified.

[0097] In this embodiment, the cylindrical body of the round bolt includes a smooth cylindrical body section and a threaded section. The threaded section is located at the front end. The threaded section is connected to the gauge, and the smooth cylindrical body section is used for sliding cooperation with the positioning block.

[0098] Specifically, as an optional implementation in this embodiment, Figure 8 As shown, the support seat assembly 6 includes

[0099] A guide rail seat 61, which is fixedly arranged on the bottom plate, and at least one supporting position is arranged on the guide rail seat 61;

[0100] The support seat 62 has a support groove at its upper end for cooperating with the main shaft 11 and a lower end thereof for slidingly cooperating with the guide rail seat 61;

[0101] When the support seat 62 moves to the support position of the guide rail seat 61 , the positioning pin 63 passes through the support seat 62 and the guide rail seat 61 to limit the support seat 62 to the support position of the guide rail seat 61 .

[0102] In this embodiment, a pair of bearings for supporting the main shaft 11 are arranged in the support groove. The support seat 62 supports the main shaft 11 through two bearings, so that the main shaft 11 can be easily adjusted in the circumferential direction.

[0103] As a preferred implementation in this embodiment, two support positions are provided on the guide rail seat 61 , and the two support positions are respectively located at both ends of the guide rail seat 61 . The user determines at which support position the support seat 62 is installed according to the actual length of the main shaft 11 .

[0104] Figure 8 In the support seat assembly 6, the positioning pin 63 is vertically elastically arranged on the guide rail seat 61, and a guide rail seat 61 is installed on a guide rail seat 61. When the support seat 62 is installed to the predetermined target position, the support seat 62 can be moved by pressing the positioning pin 63 at the corresponding position. After the support seat 62 moves into place, the positioning pin 63 bounces into the support seat 62 to fix the position of the support seat 62.

[0105] In this embodiment, handles are provided at both left and right ends of the base, and workers can use the handles to conveniently carry the clamp.

[0106] like Figure 1 The spindle assembly 1 shown includes a spindle 11, four swing arms 12 and two tooth plates 13. The swing arms 12 and the tooth plates 13 are mounted on the spindle. A pin 121 is provided on the swing arm 12, and a pin hole 132 and a plurality of tooth openings 131 are provided on the tooth plate 13.

[0107] like Fig. 9 Fig.10 As shown, the spindle assembly 1 is installed on the detection fixture, the number of swing arms 12 on the detection fixture is three, the number of swing arm detection mechanisms 4 is four, the number of tooth plate detection mechanisms 5 is three, the horizontal locking mechanism 2 is one, the vertical locking mechanism 3 is one, and the support seat 62 in the support seat assembly 6 is installed on the outer end of the guide rail seat 61.

[0108] The method of using the spindle assembly detection fixture is as follows:

[0109] First, place the spindle assembly 1 on the left and right support seats 62. The spindle 11 is matched with the bearings in the support groove. Steps are formed at both ends of the spindle 11. When assembling the spindle 11, the left support seat 62 is used as a reference to make the spindle 11 as close to the left axial direction as possible.

[0110] The horizontal locking mechanism 2 locks the spindle assembly 1 in the horizontal direction, and pulls open the horizontal clamping block 22, so that the V-shaped clamping opening of the horizontal clamping block 22 abuts against the pin 121 on one of the swing arms 12. At this time, the horizontal clamping block 22 restricts the spindle assembly 1 from axial rotation;

[0111] The vertical locking mechanism 3 vertically locks the spindle assembly 1. Fig.11 As shown, by rotating the lever 34 forward, the lever 34 moves forward with the slide 32, so that the front end of the vertical pressing block 33 moves to the upper end of the main shaft 11, and the vertical pressing block 33 vertically presses the main shaft 11 under the action of the second tension spring 35;

[0112] After the spindle assembly 1 has completed circumferential and vertical locking, it can then be inspected;

[0113] First, the pin 121 on the swing arm 12 is inspected. By moving the measuring block 42, it is observed whether the pin 121 can be inserted into the measuring hole 421 of the measuring block 42. If it can be inserted, it means that the swing arm 12 is installed properly, otherwise it means that it is unqualified.

[0114] Then, the tooth opening 131 and the pin hole 132 on the tooth plate 13 are inspected. By pressing the first round bolt 52, it is observed whether the first gauge 53 can be inserted into the tooth opening 131. By pressing the second round bolt 54, it is observed whether the second gauge 55 can be inserted into the pin hole 132. If it can be inserted, it means that the tooth plate 13 is installed qualified on the main shaft 11. If any gauge cannot be inserted into the tooth opening 131 or the pin hole 132, it means that the tooth plate 13 is unqualified.
