Description

Technical Field

[0001] The invention relates to the technical field of processing parts from bar materials, in particular to an auxiliary processing device for efficiently processing bar materials. Background Art

[0002] The structure of a bar 1 is as follows Figure 1~2 As shown, the material of the bar 1 is stainless steel or carbon steel. In a certain workshop, the bar 1 is mainly used to process the following Figure 3 The method for a workshop to process the part 3 using the bar material 1 is as follows: S1, a worker takes out a bar material 1, and then the worker draws three engraved lines 2 on one end surface of the bar material 1 and along its length at intervals, and the engraved lines 2 are as follows: Figure 4 As shown by the middle dotted line, and ensuring that the spacing between every two adjacent engraved lines 2 is equal, the three engraved lines 2 separate the bar 1 into a first processing area, a second processing area and a third processing area; S2, the worker clamps and fixes the bar 1 with the movable jaw of the vise, and ensures that the clamping position is exactly at the first engraved line 2. At this time, the first processing area of ​​the bar 1 is just exposed outside the movable jaw of the vise; S3, the worker operates the tool movement of the machine tool to process the first independent part 3 based on the first processing area; S4, the worker releases the movable jaw of the vise, and then lifts the bar 1 upward, and then clamps the bar 1 again with the movable jaw of the vise, and ensures that the clamping position is exactly at the second score line 2. At this time, the second processing area of ​​the bar 1 is just exposed outside the movable jaw of the vise; S5, the worker operates the tool movement of the machine tool to process a second independent part 3 based on the second processing area; S6, the worker repeats the operations of steps S4 to S5, and a third independent part 3 can be processed based on the third processing area of ​​the bar 1, thereby finally realizing the processing of three independent parts 3 using one bar 1; S7. The worker repeats the operations of steps S1 to S6 to continuously process parts 3 using multiple bars 1.

[0003] However, although the method used in the workshop can process the required part 3 from the bar 1, in actual operation, there are still the following technical defects: I. In step S1, three score lines 2 need to be drawn manually on the bar 1, and then the required parts 3 can be processed respectively on the basis of the first processing area, the second processing area and the third processing area of ​​the bar 1; and three score lines 2 are drawn manually on multiple bar materials 1, and the spacing between each two adjacent score lines 2 must be equal, which undoubtedly increases the processing steps, resulting in a long time to process the bar 1 into the required parts 3, thereby reducing the production efficiency of the parts 3.

[0004] II. One vise can only clamp and fix one bar 1, that is, only one bar 1 can be processed through one clamping, resulting in a long time to process all the bars 1 in the workshop into the required parts 3, which undoubtedly further reduces the production efficiency of the parts 3.

[0019] The working process of the present invention is as follows: S1. Fix two bars 1 in each clamping assembly. The specific operation steps are as follows: S11, the worker takes out two Figure 1~Figure 2As shown in the figure, the two bars 1 to be processed are respectively passed through the two mounting grooves 12 of the first clamping assembly from top to bottom, and then the bottoms of the two bars 1 are supported in the positioning grooves of the two positioning seats 21, as shown in the figure. Figure 12~Figure 16 As shown; S12, use a tool to screw down the screw head of the locking screw 14 of the clamping assembly. At this time, the locking screw 14 moves downward in cooperation with the nut 13, and the screw head of the locking screw 14 presses the expansion block 15 downward, and the expansion block 15 compresses the vertical spring 16 downward. At the same time, the expansion block 15 drives the two wedge blocks 18 to move outward, and the wedge block 18 compresses the horizontal spring 23. At the same time, the wedge block 18 drives the clamping block 19 to move outward, and the L-shaped stop 20 of the clamping block 19 moves toward the direction of the bar 1; when the screw head of the locking screw 14 can no longer be screwed down, the two clamping blocks 19 respectively fix the two bars 1, thereby realizing the tooling and fixing of the two bars 1 in the first clamping assembly. At this time, the first processing area of ​​the two bars 1 is just above the top plate 5; S13, the worker repeats the operations of steps S11 to S12 for multiple times, and then two bars 1 are fixed in each clamping assembly; S2, the worker operates the tool movement of the machine tool, and the first independent part 3 can be processed based on the first processing area. The structure of part 3 is as follows Figure 3 As shown; Among them, it can be seen from steps S1 to S2 that the worker only needs to tighten the locking screws 14 of each clamping assembly to complete the tooling fixation of multiple bars 1, thereby facilitating the worker to operate the tool of the machine tool to process the parts 3 based on the first processing area of ​​each bar 1. It can be seen that compared with the vise in the workshop, this auxiliary processing device can perform tooling fixation on multiple bars 1, thereby realizing that all bars 1 can be processed into the required parts 3 in a short time, thereby greatly improving the production efficiency of the parts 3.

[0020] S3, the worker loosens the screw head of the locking screw 14 of each clamping assembly to make the locking screw 14 move upward. At this time, under the elastic restoring force of the vertical spring 16, the expansion block 15 moves upward, and at the same time, the wedge block 18 moves inward, and the wedge block 18 moves inward toward the clamping block 19. The L-shaped stop 20 of the clamping block 19 is separated from the bar 1. At this time, the bar 1 is no longer fixed by the tooling; S4, the worker manually rotates the handwheel 22, the handwheel 22 drives the screw rod 9 to rotate around its own axis, under the cooperation of the screw rod 9 and the threaded sleeve 8 of the nut 13, the threaded sleeve 8 drives the lifting plate 7 to move upward along the guide column 6, the lifting plate 7 drives each positioning seat 21 to move upward, and the positioning seat 21 drives the bar 1 to move upward; when the handwheel 22 is rotated to a certain number of circles, the worker immediately stops rotating the handwheel 22, at this time, the second processing area of ​​each bar 1 is just above the top plate 5; S5, the worker tightens the screw head of the locking screw 14 of each clamping assembly, and each clamping assembly fixes the bar material 1 therein again; then the worker operates the tool movement of the machine tool to process a second independent part 3 based on the second processing area; S6. The worker repeats the operations of steps S3 to S5 once, and a third independent part 3 can be processed on the basis of the third processing area, thereby finally realizing the processing of multiple parts 3 using multiple bars 1.

[0021] Among them, it can be seen from steps S4 to S5 that the worker only needs to rotate the hand wheel 22 to move the second processing area of ​​each bar 1 to the top of the top plate 5, that is, the second processing area of ​​each bar 1 can be quickly placed in the processing station. It can be seen that the worker does not need to draw the equally spaced lines 2 on the bar 1 in advance before the subsequent processing, which greatly saves the processing steps, realizes the processing of the bar 1 into the required parts 3 in a short time, and further improves the production efficiency of the parts 3.
