Description

Technical Field

[0001] The utility model relates to the technical field of clamping tooling, in particular to a blank shaft clamping tooling. Background Art

[0002] In industrial products, shaft parts are suitable for maintenance operations of one or more CNC machine tool processing parts. Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission components, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts; or divided into solid shafts, hollow shafts, etc.; they are all cylindrical as a whole. Shaft parts will use clamping tooling during the production or machine assembly process.

[0003] After searching, the authorized Chinese patent announcement number CN 218905075 U discloses a transmission shaft clamping tool, which relates to the technical field of clamping tooling. The utility model includes a base, and the bottom of the base is symmetrically fixedly connected with a support gantry, and the two support gantry are provided with a transmission shaft clamping mechanism. The utility model can achieve effective clamping of transmission shafts of different axes by symmetrically arranging support gantry on the top of the base and arranging a transmission shaft clamping mechanism on the support gantry. The transmission shaft clamping tool is driven by two servo motors to clamp the transmission shaft. Compared with the method of clamping the transmission shaft by four cylinders, it is convenient for personnel to maintain the clamping tool in the later stage, and the construction cost is lower and the failure rate is also lower.

[0004] The clamping device in the above patent still has certain shortcomings. When the existing blank shaft is trimmed and polished, it often needs to be fixed with a clamping structure. Although the common clamping structure can clamp stably, most of its clamping is fixed and cannot be effectively adjusted and moved, which makes it inconvenient to polish the surface of the blank shaft and difficult to meet the clamping needs of users.

[0027] See also Figure 1-4

[0028] Embodiment 1: A blank shaft clamping tool comprises a clamping support platform 1, bottom support legs 2 are evenly arranged around the bottom end of the clamping support platform 1, two clamping adjustment components 3 are symmetrically arranged on both sides of the top end of the clamping support platform 1, a fine-tuning clamping component 4 is arranged on the clamping adjustment component 3, and a blank shaft body 5 is arranged on the top of the clamping support platform 1.

[0029] The clamping adjustment component 3 includes a clamping support plate 301 symmetrically arranged on both sides of the top of the clamping support platform 1, two limiting slide grooves 302 are symmetrically opened on both sides of the top of the clamping support platform 1, and the bottom wall of the limiting slide groove 302 is opened with a connecting slide groove 303. A fixing screw 304 is penetrated through the bottom end of the clamping support plate 301, and the bottom end of the fixing screw 304 penetrates the connecting slide groove 303, and the bottom end of the fixing screw 304 is sleeved with a fixing nut 305.

[0030] The fine-tuning clamping assembly 4 includes a side sliding groove 401 opened on the side of the top end of the clamping support plate 301, a side sliding block 402 is slidably inserted in the side sliding groove 401, a driving screw hole 403 is opened on the side wall of the side sliding groove 401, a driving screw 404 is rotatably inserted in the driving screw hole 403, and the end of the driving screw 404 is rotatably connected to the side of the side sliding block 402.

[0031] A blank shaft clamping slot 405 is provided on the side of the side sliding block 402, and two inner wall grooves 406 are symmetrically provided on the upper and lower side walls of the blank shaft clamping slot 405. A clamping contact plate 407 is provided in the inner wall groove 406. The side of the clamping contact plate 407 is rotatably connected to a contact screw 408, and the end of the contact screw 408 is threadedly rotated to pass through the side sliding block 402, and the ends of the blank shaft body 5 are inserted in the blank shaft clamping slot 405.

[0032] Embodiment 2: The difference between this embodiment and embodiment 1 is that the diameter of the fixing nut 305 is larger than the diameter of the connecting sliding gap 303 .

[0033] The fixing nut 305 is sleeved on the fixing screw rod 304 to fix the clamping support plate 301 and the clamping support platform 1 together.

[0034] Embodiment 3: The difference between this embodiment and embodiment 1 is that the side sliding groove 401 is in a cylindrical shape that matches with the side sliding block 402 .

[0035] This makes it easier for the side sliding block 402 to be inserted into the side sliding groove 401 .

[0036] Embodiment 4: The difference between this embodiment and embodiment 1 is that the side surface of the clamping and contacting plate 407 is provided with anti-slip grooves for increasing friction.

[0037] The clamping abutment plate 407 is abutted by the abutment screw 408, so that the abutment against the end of the blank shaft body 5 is more stable.

[0038] In this embodiment, the existing blank shaft often needs to be fixed with a clamping structure during trimming and grinding. Although the common clamping structure can clamp stably, most of the clamping is fixed and cannot be effectively adjusted and moved, which makes it inconvenient to grind the surface of the blank shaft and difficult to meet the user's clamping needs.

[0039] In summary, during specific operations, when the user needs to fix and clamp the blank shaft body 5, the user first needs to adjust the distance between the two clamping support plates 301 slidably inserted in the limiting slide groove 302, so that the distance between the two clamping support plates 301 is close to the length of the blank shaft body 5, and a fixing screw 304 is inserted on the clamping support plate 301, and the bottom end of the fixing screw 304 passes through the connecting sliding seam 303, and a fixing nut 305 is sleeved on the fixing screw 304, so that the clamping support plate 301 and the clamping support platform 1 are fixedly connected.

[0040] Next, the end of the blank shaft body 5 is inserted into the blank shaft clamping slot 405 opened at the end of the side sliding block 402. The user rotates the driving screw 404 to make the driving screw 404 push the side of the side sliding block 402, so that the side sliding block 402 moves toward the end of the blank shaft body 5, thereby effectively approaching and limiting the end of the blank shaft body 5. The user rotates the interference screw 408 again to make the interference screw 408 push the clamping interference plate 407 to interfere with the end of the blank shaft body 5, thereby stably clamping the blank shaft body 5 on the top of the clamping support platform 1.

[0041] The device can also clamp and fix blank shaft bodies 5 of different lengths, as well as parts of blank shaft bodies 5 whose diameters are smaller than the blank shaft clamping slots 405, which greatly expands the clamping application range of the device, thereby facilitating users to correct and polish the surface of the blank shaft body 5 and meeting user requirements.
