[0030] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0031] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: A fixture for numerically controlled blade processing, including a housing 1 for fixing the fixture housing 2. The inner wall of the housing 1 is fixedly connected with the fixture housing 2 for defining and clamping blade bodies 5 of different specifications. The inner wall of the fixture housing 2 is provided with a blade body 5 for processing metal. The front inner wall of the housing 1 is provided with a cylinder 3 as the power source of the fixture. By controlling the expansion and contraction of the cylinder 3, the clamping assembly can be driven to perform opening and closing actions. The inner wall of the fixture housing 2 is provided with a clamping assembly. The clamping assembly includes a connecting block 41 for connecting the output shaft of the cylinder 3 and two connecting rods 42. The bottom end of the connecting block 41 is fixedly connected to the top end of the output shaft of the cylinder 3. The inner wall of the top end of the connecting block 41 is rotatably connected with the connecting rod 42. The connecting rod 42 is used to connect the connecting block 41 and the fixed block 43. There are two connecting rods 42.

[0032] Referring to Figure 2 - Figure 4 , the top end of the connecting rod 42 is rotatably connected with the fixed block 43. By moving the connecting rod 42, the fixed block 43 is driven to slide on the inner wall of the guiding groove 46. The front end of the fixture housing 2 is provided with a guiding groove 46 for guiding and limiting the moving direction of the two fixed blocks 43. The outer wall of the fixed block 43 is slidably connected to the inner wall of the guiding groove 46. The rear side of the fixed block 43 is fixedly connected with a clamping block 44. The two clamping blocks 44 are driven to move in the same or opposite directions in the fixture housing 2 through the two fixed blocks 43 to clamp or release the two sides of the blade body 5. The outer surface of the clamping block 44 is slidably connected to the inner wall of the fixture housing 2. The outer side of the clamping block 44 is fixedly connected with a sliding rod 45 for improving the stability of the clamping block 44 when moving. The outer wall of the sliding rod 45 slides on the inner wall of the fixture housing 2. There are two sets of fixed blocks 43, clamping blocks 44 and sliding rods 45. The two sets of fixed blocks 43, clamping blocks 44 and sliding rods 45 are symmetrically arranged with the center line of the fixture housing 2 as the axis of symmetry. When the cylinder 3 expands and contracts, the connecting block 41 will move accordingly, driving the two inclined connecting rods 42 to move downward and at the same time driving the two fixed blocks 43 to move inward. One end of the clamping block 44 close to the blade body 5 is provided with an anti-slip pad to ensure that the blade body 5 will not slip off due to vibration or other factors during the clamping process. The anti-slip pad can provide additional friction to ensure that the blade body 5 is firmly clamped.

[0033] Referring to Figure 3 and Figure 4, a pushing component is arranged on the right side of the sliding rod 45. The pushing component includes a fixing plate 61. The left side of the fixing plate 61 is fixedly connected to the right side of the sliding rod 45, serving as the fixing basis of the pushing component. When the sliding rod 45 moves driven by the cylinder 3, the fixing plate 61 will also move accordingly. The left side of the rear end of the fixing plate 61 is fixedly connected with an elastic telescopic rod 62. When the push plate 64 pushes and adjusts the blade body 5 to a stable state and the sliding rod 45 is still running, the elastic telescopic rod 62 contracts at this time to ensure the normal operation of the sliding rod 45. The left output shaft of the elastic telescopic rod 62 is rotatably connected with a hinge rod 63. The hinge rod 63 is arranged to be inclined forward, so that when the hinge rod 63 rotates, the end of its left side hinged to the push plate 64 can generate a forward thrust or pull force. When the elastic telescopic rod 62 drives the hinge rod 63 to move, the hinge rod 63 can convert this action into the linear motion of the push plate 64. The left side of the hinge rod 63 is hinged with a push plate 64. The front outer wall of the push plate 64 slides on the inner wall of the fixture housing 2 to ensure its stable movement. The main function of the push plate 64 is to provide an additional thrust when clamping the blade body 5, ensuring that the blade body 5 is clamped more tightly between the clamping blocks 44, improving the stability and accuracy of clamping. Four limiting rods 65 are fixedly connected to the rear side of the fixture housing 2. The arrangement of the four limiting rods 65 further enhances the stability of the movement of the push plate 64. The outer walls of the four limiting rods 65 slide on the inner wall of the push plate 64, and the front outer wall of the push plate 64 slides on the inner wall of the fixture housing 2. The function of the limiting rods 65 is to limit the movement direction and distance of the push plate 64 to prevent it from moving excessively or deviating. A rubber pad is arranged at the front end of the push plate 64 to increase the friction between the push plate 64 and the blade body 5, and the softness of the rubber pad can also reduce the damage to the blade body 5.

[0034] Working principle: When in use, when it is necessary to fix the blade body 5 of different specifications, first place the blade body 5 in the fixture housing 2. At this time, start the cylinder 3 to make the output shaft of the cylinder 3 contract and drive the connecting block 41 to move downward, driving the two inclined connecting rods 42 to move downward. At the same time, the two connecting rods 42 drive the two fixing blocks 43 to slide oppositely on the inner wall of the guiding groove 46, and the two fixing blocks 43 drive the two clamping blocks 44 to slide on the inner wall of the fixture housing 2 to clamp and limit the blade body 5, thereby improving the working efficiency of the device and ensuring the stability and accuracy of the fixation of the blade body 5.

[0035] While clamping and restricting the blade body 5, the clamping block 44 drives the sliding rod 45 to slide on the inner wall of the fixture housing 2, driving the fixing plate 61 to move to the left. The fixing plate 61 drives the elastic telescopic rod 62 to move synchronously. The elastic telescopic rod 62 drives the hinged rod 63 connected by rotation to move to the left. When the hinged rod 63 rotates, one end hinged to the push plate 64 on its left side can generate a forward thrust, causing the push plate 64 to slide stably on the outer wall of the limiting rod 65. After the push plate 64 limits the blade body 5, the thrust of the fixing plate 61 to the left will drive the elastic telescopic rod 62 to contract, and the reverse acting force of the elastic telescopic rod 62 is used to improve the stability and accuracy of the clamping of the blade body 5 with different specifications by the push plate 64.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
