[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example:

[0022] See also Figure 1-3A fixture for forward and lateral processing includes a base 1, a long strip-shaped pad 2 is fixed on the base 1, and a plurality of positioning columns 4 for positioning the workpiece 3 are formed on the base 1. The positioning columns 4 are evenly distributed on both sides of the pad 2. A pressure plate 5 is movably provided on the pad 2, and the pressure plate 5 is pressed tightly to the upper side of the workpiece 3 on both sides. A locking piece 6 for locking the pressure plate 5 is also threadedly connected to the pad 2, and a clearance hole 7 is provided on the pressure plate 5 for making way for the workpiece 3 during processing.

[0023] Furthermore, a number of limiting protrusions 8 are formed on the base 1. Since the workpiece 3 itself just has a groove 9, each limiting protrusion 8 is just clamped into the groove 9 of the corresponding workpiece 3. If there is no groove 9, limiting protrusions can be set on the inner and outer sides of the workpiece 3 to achieve the limiting effect. The specific adjustment can be made according to the product structure.

[0024] Specifically, the pressing plate 5 is configured as a plurality of independently arranged pressing plates 5 evenly distributed along the length direction of the cushion block 2 , each pressing plate 5 just presses the workpieces 3 on both sides of the cushion block 2 , and each pressing plate 5 corresponds to an independent locking piece 6 .

[0025] Specifically, the locking member 6 is configured as a bolt, the lower end of the locking member 6 is threadedly connected to the pad 2 , and the locking member 6 is rotatably connected to the pressure plate 5 .

[0026] Furthermore, the upper end of the pad 2 is provided with a sliding groove 10 extending along its length direction, and each pressure plate 5 is provided with a limiting portion 11 extending into the sliding groove 10. The limiting portion 11 slides into the sliding groove 10. When the pressure plate 5 presses the workpiece 3, the lower end of the limiting portion 11 is at least 2 mm away from the bottom of the sliding groove 10.

[0027] Furthermore, a thickened portion 12 is integrally formed on the upper end surface at the middle position of each pressing plate 5 .
