Description

Technical Field

[0001] This invention relates to the technical field of processing bar stock into parts, and in particular to an auxiliary processing device for efficiently processing bar stock. Background Technology

[0002] The structure of a certain bar stock 1 is as follows Figures 1-2 As shown, this bar stock 1 is made of stainless steel or carbon steel. A certain workshop mainly uses bar stock 1 to process products such as... Figure 3 The part 3 shown is produced by a workshop using a bar stock 1 in the following manner: S1, a worker takes out a bar stock 1, and then the worker draws three engraved lines 2 at intervals along the length of one end face of the bar stock 1. The engraved lines 2 are as follows: Figure 4 As shown by the dashed lines, and ensuring that the spacing between any two adjacent scribe lines 2 is equal, the three scribe lines 2 divide the bar stock 1 into a first processing area, a second processing area, and a third processing area; S2. The worker clamps and fixes the bar stock 1 with the moving jaw of the vise, and ensures that the clamping position is exactly at the first marking line 2. At this time, the first processing area of ​​the bar stock 1 is just exposed outside the moving jaw of the vise. S3. The worker operates the machine tool's cutting tool to process the first independent part 3 based on the first processing area; S4. The worker releases the moving jaws of the vise, then lifts the bar stock 1 upwards, and then clamps and fixes the bar stock 1 again using the moving jaws of the vise, ensuring that the clamping position is exactly at the second mark 2. At this time, the second processing area of ​​the bar stock 1 is just exposed outside the moving jaws of the vise. S5. The worker operates the machine tool's cutting tool to process a second independent part 3 based on the second processing area; S6. The worker repeats steps S4 to S5 in this way, and can process the third independent part 3 on the basis of the third processing area of ​​the bar stock 1, thus finally realizing the processing of three independent parts 3 using one bar stock 1. S7. The worker repeats steps S1 to S6 in this way, and can continuously process parts 3 from multiple bars 1.

[0003] However, although the method used in the workshop can produce the required part 3 from the bar stock 1, the following technical defects still exist in actual operation: I. In step S1, three engraving lines 2 need to be manually drawn on the bar stock 1 before the required parts 3 can be processed based on the first processing area, the second processing area and the third processing area of ​​the bar stock 1. However, manually drawing three engraving lines 2 on multiple bars stock 1 and ensuring that the spacing between each pair of adjacent engraving lines 2 is equal undoubtedly increases the number of processing steps, which in turn makes it take a long time to process the bar stock 1 into the required parts 3, thereby reducing the production efficiency of parts 3.

[0004] II. One vise can only hold and fix one bar stock 1. That is to say, only one bar stock 1 can be processed through one clamping. This results in a long time required to process all the bar stock 1 in the workshop into the required part 3, which undoubtedly further reduces the production efficiency of part 3.

[0005] Therefore, there is an urgent need for an auxiliary processing device that can greatly improve the efficiency of parts production. Summary of the Invention

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description: like Figures 5-11 As shown, an auxiliary processing device for efficient processing of bar stock includes a base plate 4 and a top plate 5 fixed directly above the base plate 4. A connecting column is fixed between the top plate 5 and the base plate 4. Two guide columns 6 are fixed between the base plate 4 and the top plate 5, respectively located on the left and right sides of the base plate 4. A lifting plate 7, movable along the length of the guide columns 6, is sleeved between the two guide columns 6. A threaded sleeve 8 is fixed in the middle of the lifting plate 7, and a lead screw 9 is threadedly connected to the threaded sleeve 8. The upper and lower ends of the lead screw 9 are rotatably installed in the top plate 5 and the base plate 4, respectively. A handwheel 22 is fixedly connected to the top of the lead screw 9. Guide sleeves are fixed in the left and right ends of the lifting plate 7, and the two guide sleeves are respectively sleeved on the two guide columns 6.

[0016] Multiple clamping assemblies for fixing the bar stock 1 are spaced apart along the length of the top plate 5. Each clamping assembly includes a recessed groove 10 inclined within the top plate 5, a through hole at the bottom of the recessed groove 10, and two rectangular slots 11 within the top plate 5. The two rectangular slots 11 are located on opposite sides of the recessed groove 10 and are connected to it. Each of the two rectangular slots 11 has a mounting groove 12 extending downwards through the bottom surface of the top plate 5. A welding rod is provided directly below the through hole and welded to the bottom of the top plate 5. The nut 13 on the surface has a locking screw 14 with an internal thread that extends upward through a through hole and into the recess 10. The locking screw 14 is fitted with a liftable expansion block 15. The locking screw 14 is also fitted with a vertical spring 16. The top end of the vertical spring 16 is fixed to the top surface of the expansion block 15, and the bottom end of the vertical spring 16 is fixed to the top surface of the nut 13. Under the elastic force of the vertical spring 16, the top surface of the expansion block 15 abuts against the screw head of the locking screw 14.

[0017] The expansion block 15 has inclined surfaces 17 on both its left and right sides. Wedge-shaped blocks 18 are slidably installed in the recess 10 on both sides of the expansion block 15. The two wedge-shaped blocks 18 are symmetrically arranged about the expansion block 15. The inner ends of the two wedge-shaped blocks 18 have wedge-shaped surfaces, which respectively mate with the two inclined surfaces 17 of the expansion block 15. Clamping blocks 19 are fixed to the outer ends of the two wedge-shaped blocks 18. The two clamping blocks 19 are respectively located in two rectangular grooves 11. The outer ends of the two clamping blocks 19 have L-shaped stops 20. The shaped stop 20 is connected to the two mounting slots 12 respectively; a telescopic component is provided between the wedge block 18 and the bottom of the sink 10. The telescopic component includes a lower blind slot opened at the bottom of the sink 10 and an upper blind slot opened on the bottom surface of the wedge block 18. The upper blind slot is connected to the lower blind slot. A horizontal spring 23 is provided between the upper blind slot and the lower blind slot. One end of the horizontal spring 23 is fixed to the side wall of the lower blind slot, and the other end is fixed to the side wall of the upper blind slot. Under the elastic force of the horizontal spring 23, the wedge surface of the wedge block 18 always abuts against the inclined surface 17 of the tensioning block 15.

[0018] The top surface of the lifting plate 7 is provided with multiple sets of support seats, which are respectively opposed to each clamping component. Each set of support seats includes two positioning seats 21 fixed on the top surface of the lifting plate 7. The two positioning seats 21 are located directly below the two mounting slots 12, and positioning slots are opened on the top surface of the two positioning seats 21.

[0019] The working process of this invention is as follows: S1. Two bars 1 are tooled and fixed in each clamping assembly. The specific operation steps are as follows: S11, The worker took out two such... Figures 1-2The two bars 1 to be processed are passed through the two mounting slots 12 of the first clamping assembly from top to bottom, and then the bottoms of the two bars 1 are supported in the positioning slots of the two positioning seats 21, as shown. Figures 12-16 As shown; S12. Tighten the screw head of the locking screw 14 of the clamping assembly downwards with a tool. At this time, the locking screw 14 moves downwards in cooperation with the nut 13, and the screw head of the locking screw 14 presses down on the expansion block 15. The expansion block 15 compresses the vertical spring 16 downwards. At the same time, the expansion block 15 drives the two wedge blocks 18 to move outwards. The wedge blocks 18 compress the horizontal spring 23. At the same time, the wedge blocks 18 drive the clamping block 19 to move outwards. The L-shaped stop 20 of the clamping block 19 moves towards the bar stock 1. When the screw head of the locking screw 14 can no longer be tightened downwards, the two clamping blocks 19 fix the two bars stock 1 respectively, thereby realizing the tooling fixation of the two bars stock 1 in the first clamping assembly. At this time, the first processing area of ​​the two bars stock 1 is just above the top plate 5. S13. The worker repeats steps S11~S12 multiple times to fix two bar stock 1 in each clamping component. S2. The worker operates the machine tool's cutting tool to process the first independent part 3 based on the first processing area. The structure of part 3 is as follows: Figure 3 As shown; As can be seen from steps S1 to S2, the worker only needs to tighten the locking screws 14 of each clamping component to complete the tooling fixation of multiple bar stock 1, thereby facilitating the worker's operation of the machine tool's cutting tools to process the part 3 based on the first processing area of ​​each bar stock 1. Therefore, compared to the vise in the workshop, this auxiliary processing device can tool and fix multiple bar stock 1, thus enabling all bar stock 1 to be processed into the required part 3 in a short time, thereby greatly improving the production efficiency of part 3.

[0020] S3. The worker loosens the screw heads of the locking screws 14 of each clamping component so that the locking screws 14 move upward. At this time, under the elastic restoring force of the vertical spring 16, the tension block 15 moves upward. At the same time, the wedge block 18 moves inward and towards the clamping block 19. The L-shaped stop 20 of the clamping block 19 separates from the bar stock 1. At this time, the bar stock 1 is no longer fixed by the tooling. S4. The worker manually rotates the handwheel 22, which drives the lead screw 9 to rotate around its own axis. With the cooperation of the lead screw 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 stock 1 to move upward. When the handwheel 22 is rotated a certain number of times, the worker immediately stops rotating the handwheel 22. At this time, the second processing area of ​​each bar stock 1 is just above the top plate 5. S5. The worker tightens the screw heads of the locking screws 14 of each clamping component, and each clamping component fixes the bar stock 1 inside the tooling again; then the worker operates the cutting tool of the machine tool to process the second independent part 3 on the basis of the second processing area. S6. The worker repeats steps S3 to S5 once to process the third independent part 3 based on the third processing area, thus finally realizing the processing of multiple parts 3 using multiple bars 1.

[0021] As seen in steps S4 and S5, the worker only needs to rotate handwheel 22 to move the second processing area of ​​each bar stock 1 to the top plate 5. This means that the second processing area of ​​each bar stock 1 can be quickly positioned for processing. Therefore, it is unnecessary for the worker to pre-draw equally spaced engraving lines 2 on the bar stock 1 before subsequent processing, thus greatly saving processing steps and enabling the bar stock 1 to be processed into the required part 3 in a short time, further improving the production efficiency of part 3.
