[0030] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] Referring to Figures 1-4, a cam plate hole-turning positioning fixture 100 is used to position a cam 101 and includes a positioning ring 102, a connecting ring 103, a connecting post 104, a first rotating block 105, a pressure ring 106, and a screw 107. The connecting ring 103 is located on one side of the positioning ring 102 and is fixedly connected to the positioning ring 102. The connecting post 104 is fixedly connected to the connecting ring 103. The first rotating block 105 is rotatably connected to the connecting post 104. Specifically, the connecting post 104 is provided with a guide groove 104a extending along the circumference of the connecting post 104. The first rotating block 105 is partially located within the guide groove 104a and rotates along the guide groove 104a. The first rotating block 105 is located at one end of the connecting post 104, and the connecting ring 103 is located at the other end of the connecting post 104.

[0032] The pressure ring 106 is located within the connecting ring 103. A screw 107 is threadedly connected to the first rotating ring. The positioning ring 102 includes a receiving groove 102a for accommodating the cam 101. The shape of the receiving groove 102a matches that of the cam 101. The threaded end of the screw 107 abuts the pressure ring 106. The connecting ring 103 includes a through hole 103a. The pressure ring 106 is located within the through hole 103a and abuts the cam 101. The width of the receiving groove is smaller than the width of the cam 101. The diameter of the through hole 103a is larger than that of the pressure ring 106.

[0033] Positioning ring 102 has a first chamfer 102b to prevent scratching. Connecting ring 103 has a second chamfer 103b to prevent scratching. Connecting column 104, first rotating block 105, and screw 107 are each provided in two sets. Place cam 101 in slot 102a, then insert pressure ring 106 into through-hole 103a, bringing pressure ring 106 into contact with cam 101. Rotate the first rotating ring to the position of pressure ring 106, and tighten screw 107 until the threaded end of screw 107 contacts pressure ring 106. This secures cam 101 to positioning ring 102 via pressure ring 106, making it easier to position cam 101. Furthermore, screw 107 and pressure ring 106 secure cam 101 to positioning ring 102, making it easier to secure.

[0034] Workflow: Place cam 101 in placement groove 102a, then insert pressure ring 106 into through-hole 103a, so that pressure ring 106 abuts cam 101. Then rotate the first rotating ring to the position of pressure ring 106, and tighten screw 107 so that the threaded end of screw 107 abuts pressure ring 106. This secures cam 101 to positioning ring 102 via pressure ring 106, making it easier to position cam 101. Screw 107 and pressure ring 106 secure cam 101 to positioning ring 102, making it more convenient to secure. Positioning ring 102 is then secured using the three-jaw chuck of a lathe, allowing machining of inner hole 101a of cam 101.

[0035] The above descriptions are merely some preferred embodiments of the present disclosure and illustrate the underlying technical principles. Those skilled in the art should understand that the scope of the invention encompassed by the embodiments of the present disclosure is not limited to technical solutions formed by specific combinations of the aforementioned technical features. It also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents, without departing from the aforementioned inventive concept.
