A door closer machining jig will be described in detail below in a specific embodiment with reference to fig. 1 to 2. It is to be understood that the following description is illustrative only and is not intended as a specific limitation on the utility model.

As shown in fig. 1, a door closer machining jig includes a support plate 110, a first pressing piece 120, and a second pressing piece 130.

Wherein, the support plate 100 is used for supporting a mounting surface of the door closer 110; the first pressing block 120 and the second pressing block 130 are respectively used for pressing the lugs 140 at two ends of the door closer 110 to the support plate 100 and fixing, the side surface of the first pressing block 120 or the second pressing block 130 is provided with an avoiding hole 150, and the avoiding hole 150 is used for a drill bit to process a piston hole 160 of the door closer 110.

The fixture supports the mounting surface of the door closer 110 through the support plate 110, then the first pressing block 120 and the second pressing block 130 press the lugs 140 at two ends of the door closer 110, and as the side surface of the first pressing block 120 or the second pressing block 130 is provided with the avoiding hole 150 for the drill bit to process the piston hole 160 of the door closer 110, the piston hole 160 can be conveniently processed while the door closer 110 can be effectively pressed.

Specifically, the relief hole 150 is circular. The avoiding hole 150 is set to be circular, so that the turning head can pass through the avoiding hole more easily, and meanwhile, the avoiding hole 150 is not required to be too large, so that the strength of the first pressing block 120 or the second pressing block 130 is improved.

As shown in fig. 2, the support plate 100 is provided with a positioning pin 170 for positioning. The support plate 110 is provided with a positioning pin 170 for positioning the door closer 110 to ensure the processing precision.

Correspondingly, the side of the lug 140 close to the mounting surface is provided with a positioning hole 180 corresponding to the positioning pin 170. Since the lugs 140 are provided at both ends of the door closer 110, the positioning holes 180 are provided on the lugs 140, which facilitates positioning, and the lugs 140 themselves are also provided with bolt holes, which may be common to the positioning holes 180.

In order to ensure that the first pressing piece 120 or the second pressing piece 130 does not press the positioning pin 170 when pressing the lug 140, so that the door closer 110 is not tightly pressed. The height of the locating pin 170 is less than the depth of the locating hole 180.

In some embodiments of the present invention, a connecting block 190 is disposed between the first pressing block 120 and the second pressing block 130 on a side away from the supporting plate 100, and the connecting block 190 is used to connect the first pressing block 120 and the second pressing block 130. The first pressing block 120 and the second pressing block 130 are connected together through the connecting block 190, and can move synchronously and be controlled easily, and in addition, the pressing block is arranged on one side far away from the supporting plate 100 and cannot touch the top surface of the door closer 110.

In addition, an air cylinder 200 is further included, and the air cylinder 200 is connected to the connecting block 190 and is used for driving the first pressing block 120 and the second pressing block 130 to press or release the door closer 110. The air cylinder 200 is adopted to drive the first pressing block 120 and the second pressing block 130 to tightly press or loosen the door closer 110 through the connecting block 190, so that the speed is stable and the control is easy.

Furthermore, a stopper 210 is provided on a side surface of the door closer 110. The stop block 210 is provided to facilitate the door closer 110 to be placed at the correct position, and prevent the door closer 110 from moving during the machining process.

It is worth mentioning that the height of the stopper 210 is lower than the height of the lug 140. This arrangement prevents the first pressing piece 120 and the second pressing piece 130 from hitting the stopper 210 when pressing the lug 140.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
