Abstract
Description
Technical Field
[0001] This utility model relates to the field of worm shaft machining technology, specifically to a tapping machine for worm shaft machining. Background Technology
[0002] Worm shaft machining is a common process in manufacturing, and the tapping machine, as a key piece of equipment in this process, directly affects production quality and cost. However, a significant technical challenge in existing tapping machines for worm shaft machining is the handling of splattered chips. During worm shaft machining, the cutting and tapping operations generate a large amount of metal splatter. This splatter not only pollutes the working environment and affects the health of operators, but also damages equipment and affects machining accuracy during splattering.
[0003] Traditional tapping machine designs often neglect the issue of chip splatter, lacking effective shielding. This results in chips flying everywhere during processing, increasing cleaning difficulty and potentially posing safety hazards.
[0004] Chinese Patent (Authorization Announcement No. CN221454563U) discloses a tapping machine for manufacturing worm shafts. In this tapping machine, the cooperation between the first frame and the positioning component ensures that when the moving mechanism drives the first frame downwards, the positioning component can align the tapping head with the axis of the worm shaft to be processed, guaranteeing tapping accuracy and improving work efficiency. The cooperation between the positioning rod and the positioning seat ensures that when the positioning rod moves within the positioning seat, it simultaneously drives the tapping head to move. When the positioning rod moves to the bottom of the positioning groove, the positioning work is completed, and at this point, the tapping head is aligned with the axis of the worm shaft to be processed, ensuring tapping accuracy.
[0005] However, in practical use, the aforementioned structure makes it difficult to effectively shield the machining area during worm shaft machining, leading to the splashing of waste chips. This splashing not only pollutes the machining environment but can also damage equipment and even affect machining accuracy and operator safety. Therefore, it is necessary to optimize the design to address this issue and improve the stability and safety of the machining process. Utility Model Content

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0029] See Figures 1-3 As shown, a tapping machine for worm gear shaft processing includes a housing 1 and a material plate 2. The tapping machine for worm gear shaft processing also includes a sliding plate 3 disposed on the top of the housing 1, a first linear actuator 4 disposed on the top of the housing 1 for driving the sliding plate 3 to slide, and a tapping machine body 5 disposed on the top of the sliding plate 3 for tapping the worm gear shaft to be processed placed on the top of the material plate 2. The tapping machine body 5 for worm gear shaft processing also includes a blocking mechanism 6 and a cleaning mechanism 7. The blocking mechanism 6 is slidably disposed on the top of the sliding plate 3. The blocking mechanism 6 includes a sliding rod 61 and a protective box 62. The sliding rod 61 has multiple sliding rods and is slidably disposed on the bottom of the sliding plate 3, and the sliding rod 61 and the sliding plate 3 are in clearance fit. The protective box 62 is disposed on the bottom of the sliding rod 61. When the sliding plate 3 descends, it can drive the protective box 62 to descend synchronously until the protective box 62 abuts against the top of the material plate 2. The cleaning mechanism 7 is slidably disposed on the top of the material plate 2.
[0030] The protective box 62 is preferably made of transparent acrylic sheet, which ensures that workers can clearly see the machining status of the worm gear shaft to be tapped on top of the material placement plate 2. The protective box 62 has an opening in the middle for the tapping machine body 5 to pass through. The bottom of the protective box 62 has a clearance groove for the cleaning mechanism 7. When the protective box 62 descends and abuts against the top of the cleaning mechanism 7, the clearance groove effectively prevents waste chips generated during tapping from flying out of the protected area, ensuring a safe and clean machining environment, while also not interfering with the normal operation of the cleaning mechanism 7. This achieves effective protection of the tapping area and effectively prevents the splashing of waste chips.
[0031] This device effectively protects the tapping area by setting up a sliding plate 3 and a shielding mechanism 6 in coordination, thus effectively preventing the splashing of waste chips.
[0032] See Figure 2 and Figure 3 As shown, the tapping machine for worm shaft machining also includes a telescopic cylinder 51 and a clamping block 52; the telescopic cylinder 51 is located on the top of the machine housing 1 and below the material placement plate 2; the top of the material placement plate 2 is provided with a displacement groove 731; the clamping block 52 is slidably disposed in the displacement groove 731 and connected to the output end of the telescopic cylinder 51, and the top of the clamping block 52 is provided with a semi-circular clamping groove facing the direction of the worm shaft to be machined.
[0033] The top of the material placement plate 2 is provided with a mating block, and the top of the mating block has a semi-circular clamping groove facing the direction of the worm shaft to be processed. Both the clamping block 52 and the mating block are made of rubber, which can increase the friction with the worm shaft to be processed. The left end of the clamping block 52 is provided with a blocking part, which is rectangular and fixedly connected to the clamping block 52. The top of the material placement plate 2 is also provided with a hidden groove, which is located below the displacement groove 731 and is clearance-fitted with the blocking part. When the clamping block 52 moves the blocking part, the blocking part can move synchronously to effectively block the displacement groove 731 in the clamping state, thereby preventing waste from falling to the bottom of the material placement plate 2 through the displacement groove 731. When the clamping block 52 moves, it can push the worm shaft to be processed placed on the top of the material placement plate 2 until the worm shaft to be processed is abutted by the clamping block 52 and the mating block, at which point the clamping and fixing of the worm shaft to be processed is completed.
[0034] See Figure 4 and Figure 5 As shown, the shielding mechanism 6 also includes a return spring 63; the return spring 63 is sleeved on the outside of the sliding rod 61, one end of the return spring 63 is fixedly connected to the sliding plate 3, and the other end of the return spring 63 is fixedly connected to the shielding box 62. When the shielding box 62 abuts against the material plate 2 and the sliding plate 3 continues to descend, it can drive the return spring 63 to be in a compressed state.
[0035] When the sliding plate 3 drives the shield box 62 to descend, the shield box 62 can first contact the material plate 2. When contacting, the return spring 63 is in a compressed state and the sliding plate 3 continues to descend until the tapping machine body 5 contacts the worm shaft to be processed. Then the tapping machine body 5 starts to process the worm shaft, so that the shield box 62 can always be in contact with the material plate 2 and form an effective shielding area to prevent waste chips from splashing out.
[0036] See Figure 5 and Figure 6As shown, the cleaning mechanism 7 includes a limiting guide block 71, a guide rod 72, and a sliding scraper 73; the limiting guide block 71 has a pair and is respectively disposed on the top of the material placement plate 2 and located on both sides of the protective box 62, and each pair of limiting guide blocks 71 has a stroke groove; the guide rod 72 has a pair and is respectively disposed inside the stroke groove; the sliding scraper 73 has a pair and is respectively slidably disposed in the stroke groove, and each pair of sliding scrapers 73 is clearance-fitted with the guide rod 72.
[0037] When the protective box 62 is in the lowered state, the sliding scraper 73 can slide along the guide rod 72 in a direction away from the clamping block 52.
[0038] See Figure 6 and Figure 7 As shown, the cleaning mechanism 7 also includes a second contact scraper 74; a displacement groove 731 is provided at the bottom of the sliding scraper 73; the second contact scraper 74 has a pair and is slidably disposed at the bottom of the sliding scraper 73, and the top of the second contact scraper 74 is rounded.
[0039] The displacement groove 731 is equipped with a telescopic spring for pushing the second contact scraper 74 to slide. When the sliding scraper 73 moves, it can drive the second contact scraper 74 to move synchronously. During the movement of the second contact scraper 74, the telescopic spring can push the second contact scraper 74 to contact the mating block and the clamping block 52.
[0040] See Figures 6-8 As shown, the cleaning mechanism 7 also includes a bearing rod 75; the top of the sliding scraper 73 is provided with a kidney hole; the bearing rod 75 is rotatably disposed on the top of the second contact scraper 74, and when the second contact scraper 74 slides, it can drive the bearing rod 75 to abut against the kidney hole and rotate.
[0041] The top of the material placement plate 2 is equipped with a limiting rod that abuts against the second contact scraper 74. When the shielding box 62 descends and the second contact scraper 74 moves, it contacts the limiting rod and compresses the telescopic spring, causing the second contact scraper 74 to move to the left of the sliding scraper 73. When the shielding box 62 is fully abutting against the material placement plate 2, it ensures that the second contact scraper 74 does not interfere with the descent and shielding process of the shielding box 62. Driven by the sliding scraper 73, the second contact scraper 74 slides towards the clamping block 52. During this process, under the thrust of the telescopic spring, the second contact scraper 74 makes close contact with the clamping block 52 and the mating block respectively, thereby effectively scraping away the accumulated waste on the top of the material placement plate 2. It can automatically clean the working area of the material placement plate 2, ensuring that waste is removed in a timely manner.
[0042] See Figure 7As shown, the cleaning mechanism 7 also includes a positioning post 76 and a connecting rod 77; the positioning post 76 has a pair and is respectively arranged on both sides of the shield box 62; one end of the connecting rod 77 is rotatably connected to the positioning post 76, and the other end of the connecting rod 77 is rotatably connected to the sliding scraper 73. When the shield box 62 is lowered, the sliding scraper 73 can be driven to slide away from the clamping block 52 by the rotatably connected connecting rod 77.
[0043] When the protective box 62 descends, the sliding scraper 73 can be driven to slide away from the clamping block 52 by rotating the connecting rod 77. This enables the automatic scraping of accumulated waste on the material plate 2 by the sliding scraper 73 driven by the connecting rod 77 when tapping is completed and the protective box 62 rises.
[0044] See Figure 3 As shown, a chip removal groove 21 is provided on the top of the material placement plate 2, and the chip removal groove 21 is located below the protective box 62.
[0045] A collection box located below the chip discharge trough 21 can be installed on the top of the housing 1. When the protective box 62 rises and the sliding scraper 73 moves, the waste chips on the material plate 2 can be scraped off and discharged through the chip discharge trough 21, and the waste chips then fall into the collection box located below.
[0046] When the clamping block 52 moves, the blocking part it drives moves synchronously, effectively blocking the displacement groove 731 in the clamping state, preventing waste chips from falling to the bottom of the material plate 2 through the displacement groove 731. At the same time, the clamping block 52 can push the worm shaft to be processed on the top of the material plate 2 until the worm shaft to be processed is abutted by the clamping block 52 and the mating block, completing the clamping and fixing. Subsequently, the sliding plate 3 drives the shielding box 62 to descend. The shielding box 62 first contacts the material plate 2, at which time the return spring 63 is in a compressed state, and the sliding plate 3 continues to descend until the tapping machine body 5 contacts the worm shaft to be processed. The tapping machine body 5 starts and processes the worm shaft, and the shielding box 62 always abuts against the material plate 2, forming an effective shielding area to prevent waste chips from splashing out. During the descent of the shielding box 62, the sliding scraper 73 slides away from the clamping block 52 along the clearance fit guide rod 72. The telescopic spring in the displacement groove 731 pushes the second contact scraper 74 to slide, contacting the mating block and clamping block 52. The limiting rod at the top of the material placement plate 2 contacts the shielding box 62 as it descends and the second contact scraper 74 moves, causing the telescopic spring to compress and the second contact scraper 74 to move to the left of the sliding scraper 73. This ensures that the second contact scraper 74 does not interfere with the shielding process when the shielding box 62 is fully in contact with the material placement plate 2. Driven by the sliding scraper 73, the second contact scraper 74 slides towards the clamping block 52 and, under the thrust of the telescopic spring, makes close contact with the clamping block 52 and the mating block, scraping away debris from the top of the material placement plate 2 and ensuring a clean working area. When the shielding box 62 descends, the sliding scraper 73 is driven to slide by the rotating connecting rod 77. After tapping is completed, the shielding box 62 rises, and the connecting rod 77 drives the sliding scraper 73 to automatically scrape away debris from the material placement plate 2. The collection box on the top of the casing 1 is located below the chip discharge trough 21. When the shield box 62 rises and the sliding scraper 73 moves, the waste chips are discharged through the chip discharge trough 21 and fall into the collection box.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
