[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] A casing detection tool is used for detecting casings of nail magazines, and the casings of the nail magazines are set as casings to be measured.

[0028] like Figure 1 As shown, the sleeve to be measured includes a sleeve body 100, which is a circular tube structure with both ends open, and also includes a waist-shaped incision 400 opened at one end of the sleeve body 100 and two arc-shaped incisions 300 symmetrically arranged up and down, and a waist-shaped hole 200 opened on one side of the tube wall near the other end of the sleeve, wherein the waist-shaped incision 400 is located between the two arc-shaped incisions 300.

[0029] like Figure 2-4 As shown, the casing detection tooling includes a measuring base 1, a first measuring bracket 2, a second measuring bracket 3, a pushing block 4, a waist-shaped hole go and no-go gauge 5, and a cut three-way go and no-go gauge 6.

[0030] The measuring base 1 is preferably a plate-shaped structure.

[0031] The first measuring bracket 2 and the second measuring bracket 3 are fixed in sequence along the axial direction of the measuring base 1. The first measuring bracket 2 and the second measuring bracket 3 are respectively provided with a first sleeve mounting hole 8 and a second sleeve mounting hole 9 along the axial direction of the measuring base 1, and the first sleeve mounting hole 8 and the second sleeve mounting hole 9 are in a corresponding relationship in the axial direction of the measuring base 1, and the central axes of the two are parallel to the axis of the measuring base 1.

[0032] In addition, the second measuring bracket 3 is also fixed with a contour-limiting reference pin 7 in a direction perpendicular to the axial direction of the measuring base 1. The side wall shape of the contour-limiting reference pin 7 matches the two arc-shaped cutouts 300 on the sleeve to be measured, so that the end of the sleeve to be measured can be limited.

[0033] The pushing block 4 is located on a side of the first measuring bracket 2 away from the second measuring bracket 3 and is used to push against the sleeve to be measured.

[0034] The first measuring bracket 2 is provided with a first go / no-go gauge mounting hole 10, and the inner diameter of the first go / no-go gauge mounting hole 10 is adapted to the outer diameter of the waist-shaped hole go / no-go gauge 5; the second measuring bracket 3 is provided with a second go / no-go gauge mounting hole 11, and the inner diameter of the second go / no-go gauge mounting hole 11 is matched to the outer diameter of the cut three-way go / no-go gauge 6.

[0035] When measuring the product, the end of the sleeve to be measured with the cutout passes through the first measuring bracket 2 through the first sleeve mounting hole 8 along the axial direction of the measuring base 1, until it enters the second measuring bracket 3 through the second sleeve mounting hole 9, and the arc-shaped cutout 300 on it matches with the contoured limit reference pin 7 to achieve limit, and the other end of the sleeve is pressed by the pushing block 4; at this time, the waist-shaped hole 200 on the sleeve to be measured after limit corresponds to the position of the first go / no-go gauge mounting hole 10, and the waist-shaped cutout 400 on the sleeve to be measured corresponds to the position of the second go / no-go gauge mounting hole 11, combined with Figure 5 The waist-shaped hole go / no-go gauge 5 passes through the first go / no-go gauge mounting hole 10, penetrates the first measuring bracket 2 and passes through the waist-shaped hole 200 of the wall of the casing to be measured to measure the size and relative position of the waist-shaped hole 200, and the incision three-way go / no-go gauge 6 passes through the second measuring bracket 3 and passes through the incision at the end of the casing to be measured to measure the size and relative position of the incision, thereby realizing the measurement of the size and relative position of the entire casing to be measured.

[0036] More specifically:

[0037] Back to Figure 2The first sleeve installation hole 8 and the second sleeve installation hole 9 are both through holes with circular cross-sections, and the central axes of the two installation holes are consistent to adapt to the insertion of the sleeve to be measured; and the inner diameter of the first sleeve installation hole 8 and the second sleeve installation hole 9 matches the outer diameter of the sleeve to be measured, so that the sleeve to be detected will not move radially when entering the first sleeve installation hole 8 and the second sleeve installation hole 9. And preferably, the first sleeve installation hole 8 and the second sleeve installation hole 9 are located at the center of the bracket to ensure measurement stability.

[0038] like Figure 6 As shown, the profiling limit reference pin 7 vertically penetrates the second sleeve installation hole 9, and the profiling limit reference pin 7 is exactly located on the diameter line of the second sleeve installation hole 9 perpendicular to the axial direction of the measuring base 1 to divide the second sleeve installation hole 9 equally. Preferably, the profiling limit entry pin adopts a cylindrical pin structure. Since the two arc-shaped cutouts 300 on the sleeve to be measured are arranged symmetrically with respect to the cross-sectional diameter thereof, such an arrangement can ensure that the arc-shaped cutout 300 of the sleeve to be measured can be exactly matched with the profiling limit reference pin 7, thereby achieving limit.

[0039] It should also be noted that the contoured limit reference pin 7 can also be configured as a pin-shaped structure having only an arc surface matching the arc-shaped cutout 300 on the side of the casing to be measured, and other equivalent structures that can limit the casing to be measured should also be considered as the protection scope of this application.

[0040] Furthermore, in order to achieve the purpose that the waist-shaped hole 200 and the waist-shaped incision 400 on the measuring sleeve can be measured by the waist-shaped hole go and no-go gauge 5 and the incision three-way go and no-go gauge 6 after being limited by the contour-limiting reference pin 7, in this embodiment, the first go and no-go gauge mounting hole 10 is connected with the first sleeve mounting hole 8, and the hole end position of the first go and no-go gauge mounting hole 10 corresponds to the position of the waist-shaped hole 200 on the sleeve to be measured after installation and limiting; the second go and no-go gauge mounting hole 11 is connected with the second sleeve mounting hole 9, and the end position of the second go and no-go gauge mounting hole 11 corresponds to the position of the waist-shaped incision 400 on the sleeve to be measured after installation and limiting.

[0041] In addition, the first go / no-go gauge mounting hole 10 is arranged obliquely to the vertical surface of the measuring base 1. The second go / no-go gauge mounting hole 11 is arranged obliquely to the horizontal surface of the measuring base 1. There are two second go / no-go gauge mounting holes 11, which are respectively located on both sides of the second sleeve mounting hole 9, and the two second go / no-go gauge mounting holes 11 are on the same inclined straight line to meet the double-side measurement.

[0042] like Figure 7As shown, the push block 4 has a pushing portion with left and right sides inclined to the vertical surface of the measuring base 1, and also has a pressing surface, which is parallel to the vertical surface of the measuring base 1 and is used to contact the end of the sleeve to be measured. Correspondingly, a pressing hole 12 is provided on the measuring base 1, and the pressing hole 12 matches the pushing portion, that is, the pressing hole 12 is also inclined. When the push block 4 is working, the pushing portion is inserted into the pushing hole 12, and as the pushing portion pushes downward, the pressing surface gradually contacts the end of the sleeve to be measured and slowly presses, until the push block 4 completely presses against the sleeve to be measured until the arc-shaped cutout 300 at the other end of the sleeve is completely matched with the contoured limit reference pin 7 to limit, thereby completing the compression of the sleeve to be measured.

[0043] like Figure 7 As shown, the first measuring bracket 2 and the second measuring bracket 3 are both fixed to the measuring base 1 by means of a clamping connection. Specifically, the measuring bracket is provided with a first mounting hole 13 and a second mounting hole 14 along its axial direction, respectively. The first measuring bracket 2 is clamped to the measuring bracket via the first mounting hole 13, and the second measuring bracket 3 is clamped to the measuring bracket via the second mounting hole 14. In addition, the first measuring bracket 2 and the second measuring bracket 3 are also protruded outwardly along their axial direction to form a convex portion (not shown in the figure). During installation, whether the convex portion contacts the surface of the measuring base 1 is used to determine whether the two measuring brackets are installed in place.

[0044] The specific implementation principle of the utility model is: when measuring the product, first put the product into the detection fixture through the first sleeve installation hole 8 and the second sleeve installation hole 9, then install the pushing block 4 to push the product to the contour limit reference pin 7 for limiting, and finally use the waist hole go and no-go gauge 5 and the incision three-way go and no-go gauge 6 to detect the product size and relative position respectively.

[0045] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
