[0002] A milling machine is a commonly used metal cutting machine tool, which is mainly used to process complex shapes such as planes, bevels, grooves, holes, etc. on workpieces; it uses a rotating multi-edged tool (called a milling cutter) to remove materials to achieve the required size and surface finish.

[0003] The Chinese invention patent with publication number CN110961703A disclosed a milling machine for thermal insulation strips on April 7, 2020, which belongs to the field of milling machine fixtures. A milling machine for thermal insulation strips includes a base and a cylinder connected to the base, and also includes a first slide bar, which is detachably connected to the base; a plurality of clamps, which are slidably connected to the first slide bar; and symmetrical blocks are provided on two adjacent clamps; the clamp also includes a support rod, and a blocking component for limiting the distance between the plurality of clamps is movably connected to the support rod; the present invention places a plurality of thermal insulation strips between a plurality of clamps, so that the cylinder can be started to quickly fix the plurality of thermal insulation strips, and the distance between the plurality of clamps is limited by the blocking component, so as to facilitate the processing of the cutting component of the milling machine, and can realize large-scale processing and improve work efficiency.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the batch clamping device in the prior art has a complex clamping space, and requires manual hand-held workpieces to be placed one by one in the corresponding clamping space, and then pushed by the cylinder to clamp and fix them centrally. This method is inefficient, and after the milling process is completed, the processed workpieces cannot be taken out in batches, and the efficiency cannot be maximized. Summary of the invention

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] See also Figure 1-4 As shown, a batch processing fixture for a workpiece milling machine comprises a fixed base plate 1 for connecting to a milling machine worktable; a limiting groove 2 is provided on the upper surface of the fixed base plate 1, so that after the workpiece is placed in the limiting groove 2, it is not easy to separate from the fixed base plate 1 and cause it to fall, so that a number of workpieces to be processed can be poured in at one time, and then quickly arranged manually; then a limiting shaft 3 is inserted into the limiting groove 2; and a plurality of groups of limiting partitions 4 and elastic members 5 are sleeved on the limiting shaft 3, and the limiting partitions 4 can push the two limiting partitions 4 when not acted upon by external forces through the elastic members 5. A gap is created between the limiting partitions 4, thereby facilitating the insertion of the workpiece to be processed; a thrust cylinder 6 is fixedly connected to the corresponding limiting partition 4 on the fixed base plate 1, and the thrust cylinder 6 pushes the closest limiting partition 4 to move along the limiting axis 3, thereby clamping the workpiece between the limiting partitions 4, so that multiple workpieces can be clamped at one time for milling processing, and the number of workpieces that need to be processed can be quickly dumped at one time, and the workpiece can be quickly placed manually between multiple limiting partitions 4, and multiple workpieces can be quickly taken out after processing is completed, making the entire processing process more efficient.

[0023] By detachably fixing the limiting strip 8 in the limiting groove 2; the limiting partition 4 is provided with a limiting slot 9 corresponding to the limiting strip 8, and through the sliding and limiting cooperation of the limiting slot 9 and the limiting partition 4, the limiting partition 4 can remain parallel to each other when moved by horizontal force, so that the workpiece can be clamped stably, and at the same time, the contact between the workpiece and the elastic member 5 can be limited, so that the long-term service life is longer.

[0024] By symmetrically opening the receiving grooves 11 on the fixed base plate 1; opening the avoidance fillet 10 in the receiving grooves 11; and inserting the fifth fastener 22 in the holes on the receiving grooves 11 and the fixed base plate 1, the protruding space is reduced, thereby making it safer during transportation, movement and fixing.

[0025] A first fastener 13 is threadedly connected through symmetrical openings on both sides of the fixed base plate 1; a movable plate 14 is sleeved on the first fastener 13; a stepped shaft 15 is rotatably connected between the movable plates 14; a handle 16 is inserted into a hole on one side of the stepped shaft 15, and one end of the movable plate 14 is limited by the first fastener 13, so that the other end of the movable plate 14 and the stepped shaft 15 can rotate around the first fastener 13, so that the stepped shaft 15 can be placed in the accommodating groove 11 in the initial state without affecting the mechanical processing of the milling machine. At the same time, after the processing of the workpiece is completed, the push cylinder 6 is reset, the movable plate 14 is rotated to make the stepped shaft 15 contact with the upper surface of the workpiece, and then the handle 16 is rotated, so that the stepped shaft 15 is rotated to drive the workpiece after processing to move away from the limiting partition 4, and from the limiting groove 2 to separate from the fixed base plate 1, thereby realizing the rapid transfer of the processed workpiece.

[0026] By providing an avoidance groove 17 in the limiting groove 2 corresponding to the stepped shaft 15, when the stepped shaft 15 is in a horizontal state, the highest point does not exceed the upper surface of the fixed base plate 1, so as not to affect the machining of the milling machine.

[0027] A plurality of second fasteners 19 are threadedly connected by opening holes on the upper surface of the fixed base plate 1; a reinforcing plate 18 is sleeved on the second fasteners 19; the reinforcing plate 18 is detachably fixed to the propulsion cylinder 6, and the propulsion cylinder 6 is fixedly connected to the fixed base plate 1 and the reinforcing plate 18 at the same time through the reinforcing plate 18, so that when the limiting partition 4 is squeezed, no deformation will occur, resulting in failure to push and squeeze normally.

[0028] By slidingly fitting the limiting groove 2 at one end of the limiting partition 4, a guide groove 7 is symmetrically opened at the other end. The guide groove 7 makes it faster and more convenient to insert the workpiece between the two limiting partitions 4, and at the same time, it is more parallel and stable when moved under force.

[0029] By opening a plurality of fixing grooves 12 on the side of the fixing base plate 1, it can be fixed by means of T-nuts, so that it is more convenient and stable to fix it on the workbench of the milling machine.

[0030] The third fastener 20 is threadedly connected to a hole in the movable plate 14 corresponding to the fixed base plate 1, and the third fastener 20 is rotated to squeeze the side of the fixed base plate 1 to achieve a rotation angle of the fixed movable plate 14, so that it is more stable when used.

[0031] A fourth fastener 21 is threadedly connected to a hole corresponding to the limiting shaft 3 on the upper surface of the fixed base plate 1 , and the limiting shaft 3 is squeezed by rotating the fourth fastener 21 , so that the limiting shaft 3 is stably fixed.
