Referring to fig. 1 and 2, a front mat board seat 20 and a rear mat board seat, that is, a front mat board seat and a rear mat board seat, are respectively disposed at two ends of a center sill 10 of a railway wagon, the center sill 10 needs to be provided with a plurality of mounting holes for mounting the front mat board seat and the rear mat board seat, the front mat board and the rear mat board need to be provided with a plurality of mounting holes, and the mounting holes for mounting the front mat board seat and the rear mat board seat at two ends of the center sill 10 need to be in one-to-one correspondence and ensure concentricity, so that the center sill 10 and the front mat board seat and the rear mat board seat need to be drilled synchronously. However, since the two ends of the center sill 10 are provided with a plurality of mounting holes for mounting the front and rear mat board seats and a plurality of mounting holes for mounting the front and rear mat board seats, positioning in a scribing positioning manner easily causes inaccuracy of relative positions between the plurality of mounting holes, which leads to inaccuracy of drilling and further influences mounting and fixing of the front and rear mat board seats on the center sill 10, and further may cause potential safety hazards.
As shown in fig. 1 to 4, in this embodiment, the center sill 10 has a side wall 11 and an upper edge plate 12 and a lower edge plate 13 provided in the longitudinal direction (up-down direction in the drawing) of the side wall 11 and protruding outward with respect to the side wall 11, and the inner sides of the side walls 11 at both ends (left-right direction in the drawing) of the center sill 10 are provided with a front mat plate holder 20 and a rear mat plate holder; the front mat base 20 and the rear slave base 30 have lateral end faces (left-right direction in the drawing), respectively. The drill jig for synchronously drilling the front and rear clump plate seats and the middle beam 10 is arranged on the outer side of the side wall 11 of the middle beam 10 to position and drill the mounting holes of the front and rear clump plate seats, ensures that the mounting holes for the front and rear clump plate seats on the middle beam 10 are accurately positioned, guides the drill jig through the drill bushing during drilling, and ensures that the side wall 11 of the drill hole perpendicular to the middle beam 10 is derived from the front and rear clump plate seats on the inner side of the side wall 11 of the middle beam 10. In the drill jig for synchronously drilling the front and rear clump plate seats and the middle beam 10, the drill plate 100 of the drill jig is provided with positioning holes 110 corresponding to mounting holes for mounting the front and rear clump plate seats at two ends of the middle beam 10, and the length of the drill plate 100 is matched with the mounting positions of the front and rear clump plates at two ends of the middle beam 10. When the drilling template 100 is attached to the side surface of the center sill 10, the position of the drilling template 100 relative to the center sill 10 is adjusted, so that the longitudinal positioning assembly 200 abuts against the longitudinal end surface of the center sill 10, namely the upper edge plate 12 or the lower edge plate 13; the lateral positioning assembly 300 is brought into abutment against the lateral end face of the front mat base 20 or the rear panel. In particular, in the present embodiment, the longitudinal positioning assembly 200 is abutted on the lower edge plate 13, so that the jig plate 100 is positioned relative to the center sill 10 in the longitudinal direction; the lateral positioning assembly 300 is abutted on the lateral end face of the rear mat seat, thereby positioning the jig plate 100 in the lateral direction with respect to the center sill 10. In other embodiments, the positioning positions of the longitudinal positioning assembly 200 and the transverse positioning assembly 300 on the jig plate 100 can be changed from the present embodiment by changing the arrangement positions of the longitudinal positioning assembly 200 and the transverse positioning assembly 300 on the jig plate 100, for example, the longitudinal positioning assembly 200 abuts on the upper edge plate 12, thereby positioning the jig plate 100 in the longitudinal direction with respect to the center sill 10; the lateral positioning assembly 300 is abutted against the lateral end face of the front mat nest 20, thereby positioning the jig plate 100 laterally with respect to the center sill 10.
As an alternative embodiment, the longitudinal positioning assembly 200 includes a positioning frame 210, and the positioning frame 210 includes: the connecting and fixing part 211 is used for being connected to the drill jig plate 100, and a screw hole for the positioning and fixing piece to penetrate through is formed in the connecting and fixing part 211; and a longitudinal positioning part 212 connected to the connecting part and forming a groove for accommodating a transverse end surface of the center sill 10 together with the connecting and fixing part 211. Accordingly, the positioning and fixing assembly 400 includes: the longitudinal fixing piece 410 is provided with an external thread matched with the screw hole and is used for penetrating into the screw hole to fix the longitudinal positioning assembly 200; and the transverse fixing member 420 is provided with a column part matched with the positioning hole 110 and is used for being arranged in an initial mounting hole drilled initially on the center sill 10 in a penetrating manner.
In the above embodiment, as shown in fig. 3 and 4, the transverse end surface, i.e., the lower edge plate 13, of the center sill 10 is located in the groove formed by the connecting fixing portion 211 and the longitudinal fixing portion, the longitudinal fixing member 410 of the positioning and fixing assembly 400 is placed in the screw hole and is gradually screwed down and abutted on the lower edge plate 13 of the center sill 10 through the screw thread in the screw hole, and at the same time, the longitudinal positioning portion 212 is abutted on the lower edge plate 13 of the center sill 10 from below, and the lower edge plate 13 of the center sill 10 is clamped in the groove through the longitudinal positioning portion 212 and the longitudinal fixing member 410, so that the longitudinal positioning and fixing of the drill jig are realized.
In the above embodiment, preferably, the longitudinal positioning portion 212 is provided with a protrusion 213 at a position corresponding to the screw hole of the connection fixing portion 211, and the longitudinal positioning portion 212 abuts against the lower edge plate 13 of the center sill 10 through the protrusion 213, so as to avoid the problem of inaccurate positioning caused by an excessively large abutting surface.
As an alternative embodiment, as shown in fig. 3 and 4, the positioning frame 210 further includes a positioning reinforcing plate provided on the jig plate 100, and the connection fixing portion 211 is connected to the jig plate 100 through the positioning reinforcing plate. Through the positioning reinforcing plate, the connection strength between the connection fixing part 211 and the drilling jig plate 100 can be enhanced, and the connection fixing part 211 and the drilling jig plate 100 can be ensured to be vertically connected.
As an alternative, as shown in fig. 3 and 4, the depth of the groove formed by the longitudinal positioning portion 212 and the connecting fixing portion 211 matches the width of the transverse end surface of the center sill 10, so that the free end of the longitudinal positioning portion 212 extends to the inner side of the center sill 10. In this embodiment, by extending the free end of the longitudinal positioning portion 212 to the inner side of the center sill 10, the lateral positioning assembly 300 can be disposed at the free end of the longitudinal positioning portion 212, so that the lateral positioning assembly 300 can be positioned laterally by the front and rear mat holders.
As an alternative embodiment, the lateral positioning assembly 300 is rotatably disposed on the drilling template 100 or the longitudinal positioning assembly 200, so that the lateral positioning assembly 300 rotates relative to the drilling template 100 or the longitudinal positioning assembly 200.
In this embodiment, by rotating the lateral positioning assembly 300 relative to the jig plate 100 or the longitudinal positioning assembly 200, the lateral positioning assembly 300 can be compactly disposed on the jig plate 100 or the longitudinal positioning assembly 200 and can pass around the upper edge plate 12 or the lower edge plate 13 of the center sill 10 so as to be able to abut on the lateral end surfaces of the front and rear mat plate holders located inside the center sill 10. In this embodiment, the transverse positioning assembly 300 may be disposed on both the drilling template 100 and the longitudinal positioning assembly 200, specifically, the transverse positioning assembly 300 may be determined by positioning the transverse positioning assembly 300 by means of the front mat base 20 or the rear mat base 30, for example, when the transverse positioning assembly 300 is transversely positioned by means of the front mat base 20, the transverse positioning assembly 300 may be disposed at a position of the drilling template 100 adjacent to the front mat base 20, such as a position near the left end of the center sill 10 in fig. 3; for another example, when the lateral positioning assembly 300 is laterally positioned by means of a rear mat board mount, the lateral positioning assembly 300 may be disposed at a position of the jig plate 100 adjacent to the rear mat board mount, such as a position near the right end of the center sill 10 in fig. 3. In this embodiment, the lateral positioning assembly 300 is rotatably disposed on the jig plate 100 and can be laterally positioned by means of the front and rear mat boards by rotating relative to the jig plate 100 to the inner side of the side wall 11 of the center sill 10.
Preferably in this embodiment, as shown in fig. 3 and 4, the transverse positioning assembly 300 is rotatably provided on the longitudinal positioning assembly 200 and is positioned transversely by means of the front and rear mat boards by rotating to the inner side of the side wall 11 of the center sill 10 with respect to the longitudinal positioning assembly 200. Meanwhile, if the lateral positioning assembly 300 is rotatably disposed on the longitudinal positioning assembly 200, the disposition position of the longitudinal positioning assembly 200 on the jig plate 100 should also be adaptively adjusted so that the lateral positioning assembly 300 is as close as possible to the front mat plate holder 20 or the rear mat plate holder for positioning by means thereof, thereby making the entire structure of the jig more compact and facilitating the adjustment of the position. Since the longitudinal direction positioning assembly 200 is extended more toward the inner side of the side plate of the center sill 10 with respect to the jig plate 100, disposing the lateral direction positioning assembly 300 on the longitudinal direction positioning assembly 200 enables the structure of the lateral direction positioning assembly 300 to be more compact and facilitates the rotation thereof with respect to the longitudinal direction positioning assembly 200.
Further preferably, the lateral positioning assembly 300 comprises: a positioning shaft 310 disposed on the longitudinal positioning portion 212; and a transverse positioning portion 320, disposed on the positioning rotating shaft 310, for abutting against the longitudinal end surface made by the front slave plate seat or the rear slave plate.
In this embodiment, the positioning rotating shaft 310 of the transverse positioning assembly 300 is disposed on the longitudinal positioning portion 212, and preferably, the positioning rotating shaft 310 of the transverse positioning assembly 300 is disposed at the free end of the longitudinal positioning portion 212, that is, after the drill plate 100 is attached to the side wall 11 of the middle beam 10 and longitudinally positioned, the transverse positioning portion 320 can rotate relative to the longitudinal positioning portion 212 to the inner side of the side wall 11 of the middle beam 10 under the action of the positioning rotating shaft 310, so that the transverse positioning portion 320 can abut against the longitudinal end surface of the front mat board seat 20 or the rear slave board seat 30 through transverse adjustment to achieve transverse positioning. As shown in fig. 3 and 4, in this embodiment, the cross positioning portion 320 abuts on the rear mat seat.
In other embodiments, the positioning frame 210 may be other structures that can achieve the longitudinal positioning, for example, the positioning frame 210 is vertically disposed at the longitudinal edge of the drilling template 100. The positioning frame 210 may be a separate structure and disposed on the jig plate 100 by riveting, or the like, and the positioning frame 210 may also be a structure integrated with the jig plate 100, integrally formed with the jig plate 100, and perpendicular to the jig plate 100. The specific structure of the positioning frame 210 is adjusted according to the components and applications arranged thereon. If the spacer 210 is vertically arranged at the lower longitudinal edge of the jig plate 100, the spacer 210 is provided with a longitudinal positioning surface for abutting against the lower edge plate 13 of the center sill 10, and further comprises an extension plate extending to the outer side of the side wall 11 of the center sill 10 so that the transverse positioning part 320 arranged thereon can extend to the inner side of the side wall 11 of the center sill 10 by bypassing the side wall 11 of the center sill 10 and the lower edge plate 13 so as to be on the transverse end surface of the front and rear mat boards seats.
In other embodiments, the lateral positioning assembly 300 may be disposed on the longitudinal positioning assembly 200 or the drill plate 100 in other manners, and the structure of the lateral positioning assembly 300 may be changed such that the position where it is used to contact the lateral end surface of the front and rear mat holders extends to the inner side of the center sill 10.

As shown in fig. 3 and 4, in the above embodiment, the positioning frame 210 is used for fixing the transverse positioning assembly 300 in addition to the longitudinal positioning and fixing, and the structure itself is complicated. Preferably, in the drilling jig, one positioning frame 210 is arranged, and an auxiliary positioning frame 220 for the auxiliary positioning frame 220 is arranged, wherein the auxiliary positioning frame 220 is only used for longitudinal positioning and fixing, and the transverse positioning assembly 300 is not required to be arranged.
As an alternative embodiment, the positioning and fixing assembly 400 includes:
the longitudinal fixing piece 410 is provided with an external thread matched with the screw hole and is used for penetrating into the screw hole to fix the longitudinal positioning assembly 200; and the combination of (a) and (b),

In this embodiment, as shown in fig. 3, the transverse fixing member 420 is a pin, and after two mounting holes are drilled in the center sill 10 through the positioning holes 110 of the drill plate 100 and the positioning and guiding action of the drill bushing, the pin is inserted into the positioning holes 110 and the drilled initial mounting holes to perform transverse positioning of the drill jig. The method and the device have the advantages that the drilled mounting holes are utilized for positioning, so that the phenomenon that the drilling jig is shifted to influence the change of the drilling position in the subsequent drilling process after installation is avoided.
As an alternative embodiment, the jig further includes a handle 500, and the handle 500 is disposed on the jig plate 100. It is further preferable that the handles 500 include two handles, which are respectively disposed at both ends of the jig plate 100, and facilitate the drilling of the jig by providing the handles 500.
In the above embodiment, the drill jig for synchronously drilling the front and rear mat boards and the center sill 10 is preferably made of a non-deformable metal material, such as cast iron, stainless steel, etc.
