The base is provided with positioning holes for installing the drill sleeve. The positioning holes are arranged in pairs side by side on the base. The base is provided with two reserved holes that penetrate its bottom and correspond one-to-one with the positioning holes. One side of the base is provided with two workpiece holes that are horizontally connected to the positioning holes. One end of the workpiece hole is provided with a positioning plate that is connected to the base by fastening bolts. The positioning plate is provided with two positioning screws that correspond one-to-one with the workpiece holes. The other end of the workpiece hole is provided with a clamping plate, and the clamping plate is provided with clamping bolts that are connected to the threaded holes opened on the base.

[0005] Preferably, the base is provided with a transverse reserved groove that is parallel to and through the positioning hole.

[0006] Preferably, the positioning plate is provided with a longitudinal reserved groove, which is located between two positioning screws.

[0007] Preferably, chip removal grooves are provided at both the top and bottom of the workpiece hole.

[0008] Preferably, the positioning plate has an L-shaped opening on the side facing the workpiece hole.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides a universal drilling jig for a dual-station rocker arm shaft. The base can hold two workpieces simultaneously. The workpieces are inserted into the workpiece holes, and the positioning screws adjust the connection depth between the base and the positioning plate to position the end of the workpiece shaft. By tightening the clamping bolts, the clamping plate can clamp the two workpieces apart. A drill sleeve is inserted into the positioning hole, the bench drill is powered on, and the drill rocker arm is pressed down to achieve dual-station drilling. This utility model has a reasonable design and simple structure, and can drill two rocker arm shaft workpieces simultaneously, which is beneficial to improving production efficiency and is suitable for large-scale promotion.

[0012] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0013] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0014] Examples, such as Figures 1-4 As shown, this utility model provides a universal drill jig with a rocker arm shaft and two working positions, including a drill sleeve 1 and a base 2. The base 2 is provided with positioning holes 21 for installing the drill sleeve 1. The positioning holes 21 are arranged in pairs side by side on the base 2. The base 2 is provided with two reserved holes 22 that penetrate its bottom and correspond one-to-one with the positioning holes 21. The reserved holes 22 leave sufficient margin for the downward stop point of the drill bit. Two workpiece holes 23 that are horizontally connected to the positioning holes 21 are provided on one side of the base 2. One end of the workpiece hole 23 is provided with a positioning plate 4 that is connected to the base 2 by fastening bolts 3. The positioning plate 4 is provided with two positioning screws 5 that correspond one-to-one with the workpiece hole 23. The other end of the workpiece hole 23 is provided with a clamping plate 6. The clamping plate 6 is provided with clamping bolts 7 that are connected to the threaded holes 24 opened on the base 2.

[0015] Specifically, the base 2 can hold two workpieces 8 simultaneously. Workpieces 8 are inserted into workpiece holes 23. The positioning screws 5, by adjusting their connection depth with the positioning plate 4, can position the ends of the workpieces 8. The clamping bolts 7 can be tightened to clamp the two workpieces 8 at intervals. A drill sleeve 1 is inserted into the positioning hole 21. The bench drill power is turned on, and the drill arm is pressed down. The drill bit passes through and drills a hole in the workpiece 8, achieving dual-station drilling. Therefore, this equipment can be used with a bench drill to drill holes in two rocker arm shaft workpieces 8. The alignment of the two rocker arm shaft workpieces 8 is good, which helps save clamping time, improves production efficiency, and makes it highly practical.

[0016] To facilitate real-time observation of the drilling process, this invention provides a transverse pre-reserved groove 25 on the base 2, which is parallel to and penetrates the positioning hole 21; simultaneously, a longitudinal pre-reserved groove 41 is provided on the positioning plate 4, positioned between two positioning screws 5. This allows a portion of the drilling area to be exposed in the field of vision, avoiding blind drilling.

[0017] To ensure drilling quality, the present invention provides chip removal grooves 26 at both the top and bottom of the workpiece hole 23. This provides a certain chip removal space for the chips generated during processing and also plays a role in heat dissipation to a certain extent, which helps to ensure the quality of actual drilling.

[0018] To improve the reliability of clamping workpiece 8, the positioning plate 4 provided by this utility model has an L-shaped opening 42 on the side facing the workpiece hole 23. The L-shaped opening 42 is located above the fastening bolt 3. This allows the root nodes of the positioning plate 4, the fastening bolt 3, and the positioning screw 5 to be staggered. In addition, the contact nodes between the end of the positioning screw 5 and the end of the workpiece 8 form a relatively three-dimensional triangular system in terms of force. Furthermore, the engagement depth at different thread positions can effectively improve the clamping quality of the positioning plate 4, the base 2, and the clamping plate 6 on the workpiece 8, which is beneficial to improving the drilling accuracy and extending the actual service life of the positioning screw 5 and the fastening bolt 3.

[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
