Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of protective structures, and in particular to an automatic grinding device for the shape of a bulletproof product with a special curved surface structure. BACKGROUND

[0002] With the development of bulletproof technology, there is an increasing demand for bulletproof products with special curved surface structures based on engineering design. Compared with traditional flat bulletproof equipment, bulletproof products with special curved surface structures have the characteristics of high adhesion, good comfort, and excellent multi-angle protection performance. For example, multi-curved special bulletproof plates, conformal protective armor, and bionic multi-special sheet splicing bulletproof equipment.

[0003] Currently, bulletproof products with special curved surface structures are typically made of bullet-resistant materials and functional materials. Typical bullet-resistant structures include ceramic materials such as silicon carbide, boron carbide, and aluminum oxide, as well as metal materials such as titanium alloy and special bulletproof steel. Typical functional materials include carbon fiber, PE, aramid, and UD cloth. In the manufacturing process of bulletproof products with special curved surface structures, multiple layers of functional materials and bullet-resistant materials are combined at high strength by hot pressing. To ensure complete adhesion of the functional materials to the bullet-resistant materials, the size of the functional materials is often designed to be larger than that of the bullet-resistant materials before hot pressing. Therefore, after hot pressing, the functional materials that exceed the edges of the bullet-resistant materials need to be ground or cut to make the edges of the functional materials and the bullet-resistant materials flush, thereby avoiding the overall aesthetic appearance and affecting the overall performance of the bulletproof product.

[0004] In the batch production process of the prior art, manual grinding tools such as handheld grinders are used to grind the edges of the special curved surface. The manual grinding method is inefficient, consumes a lot of labor intensity, increases labor costs, and has certain risks, which can cause personal injury. Moreover, the consistency of the ground products cannot be guaranteed. In addition, due to the special curved surface characteristics of bulletproof products, the existing grinding machines cannot achieve uninterrupted grinding, which affects the production efficiency.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Example 1:

[0026] like Figures 1-4 As shown: An automatic grinding device for the shape of bulletproof products with irregular curved surface structure, characterized in that: it includes a support base plate 10, a rotating component 20, a fixing component 30 and a grinding component 40. The support base plate 10 is provided with a plurality of control buttons 11 for controlling the operation of various motors or cylinders, such as emergency stop button, power button, forward jog button, reverse jog button, continuous work button, etc.

[0027] The rotating assembly 20, the fixing assembly 30, and the grinding assembly 40 are respectively disposed on the end face of the supporting base plate 10, and the rotating assembly 20 and the fixing assembly 30 are disposed opposite to each other (e.g., Figure 1 , Figure 2 (As shown); The rotating assembly 20 includes a rotating bracket 21, a rotating motor 22, and a clamping mechanism. The rotating bracket 21 is fixedly mounted on the end face of the support base plate 10, and the rotating motor 22 is mounted on the side of the rotating bracket 21 away from the fixed assembly 30. The output shaft of the rotating motor 22 passes through the rotating bracket 21 and is followed by the clamping mechanism. The fixed assembly 30 includes a fixed bracket 31, a clamping cylinder 32, and a first clamping block 33. The fixed bracket 31 is fixedly mounted on the end face of the support base plate 10, and the clamping cylinder 32 is mounted on the side of the fixed bracket 31 away from the rotating assembly 20. The output end of the clamping cylinder 32 passes through the fixed bracket 31 and is followed by the first clamping block 33. The clamping mechanism includes a second clamping block 231, a limiting bracket 232, and a lever 233. The second clamping block 231 is fixedly mounted on the output shaft of the rotating motor 22 corresponding to the first clamping block 33. An "L"-shaped limiting bracket 232 is mounted on the bottom surface of the second clamping block 231 and on the side away from the grinding assembly 40 (e.g., Figure 1 ,Figure 2 The outer wall at the corner of the limiting support 232 is provided with a push block 233, and the limiting support 232 has a certain width, thereby ensuring the limiting and supporting effect on the special-shaped curved surface structural member 50.

[0028] The grinding assembly 40 is arranged between the rotating assembly 20 and the fixed assembly 30, and includes a support table 41, a sliding table 42, a spring seat 43, an attached spring 44 and a motor mounting seat 45. The support table 41 is arranged on the end surface of the support bottom plate 10, and the support table 41 is provided with a guide rail and the spring seat 43. The spring seat 43 is located at the end of the guide rail away from the rotating assembly 20. The sliding table 42 is arranged on the guide rail and is in sliding connection with the guide rail (i.e., the sliding table 42 can freely slide on the guide rail, thereby controlling the motor mounting seat 45 to move away from or close to one side of the rotating assembly 20). The motor mounting seat 45 is arranged on the end surface of the sliding table 42 and is connected with the spring seat 43 through the attached spring 44. A motor box 46 is arranged at the end of the motor mounting seat 45 away from the attached spring 44. A grinding motor is arranged in the motor box 46, and the output shaft of the grinding motor is parallel to the center line of the first clamping block 33 and the second clamping block 231 (i.e., the axis of the output shaft of the grinding motor is perpendicular to the direction of the guide rail track). A grinding rotary file 460 is fixedly arranged on the output shaft of the grinding motor, and a convex rib 461 is arranged on the side surface of the motor box 46 away from the motor mounting seat 45. The convex rib 461 corresponds to the push block 233.

[0029] The cross section of the convex rib 461 is a semicircular structure, and the end of the push block 233 away from the limiting support 232 is provided with a spherical surface structure. The height of the convex rib 461 (i.e., the thickness of the convex rib 461 in the vertical direction) is greater than the diameter of the push block 233 (spherical surface structure).

[0030] The side surface of the first clamping block 33 and the second clamping block 231 away from each other is provided with longitudinally and transversely intersecting rubber convex ribs. One is to avoid damage to the special-shaped curved surface structural member 50 during clamping through the buffering effect of the rubber convex ribs. Two is to increase the internal friction during rotation by using the longitudinally and transversely intersecting rubber convex ribs with extrusion force, thereby avoiding the shift of the special-shaped curved surface structural member 50 and forming a stable clamping of the special-shaped curved surface structural member 50. Three is to adapt to different curved surfaces of the special-shaped curved surface structural member 50 by using the extrusion deformation of the rubber convex ribs, thereby ensuring effective clamping of various curved surfaces.

[0031] Working principle:

[0032] In the initial state, there is a certain distance between the first clamping block 33 and the second clamping block 231.

[0033] In use, first, the special-shaped curved surface structural member 50 is placed between the two limiting supports 232, so that the bottom surface of the special-shaped curved surface structural member 50 is in contact with the limiting support 232 on the bottom, and one side edge of the special-shaped curved surface structural member 50 is in contact with the limiting support 232 on the side (for example, as shown in FIG. 1). Figure 1、 Figure 2 As shown in FIG. 6, the first clamping block 33 is moved to the side close to the second clamping block 231 until the rubber protrusions on the opposite side of the first clamping block 33 are compressed, and the special-shaped curved structure 50 is firmly clamped; then, the rotary motor 22 and the grinding motor are simultaneously started, the rotary motor 22 rotates to drive the second clamping block 231 to rotate, and the special-shaped curved structure 50 rotates with the second clamping block 231 due to the limitation of the limiting support 232 and the friction of the rubber protrusions, the grinding motor drives the grinding rotary file 460 to rotate to realize the grinding and cutting of the excess material on the outer edge of the special-shaped curved structure 50; during the grinding process, the extension and shortening of the attached spring 44 and the sliding of the sliding table 42 on the upper surface of the support table 41 are matched to adapt to the different outer edge curves of the special-shaped curved structure 50, thereby realizing adaptive grinding.

[0034] In addition, during the grinding process, the cooperation of the push block 233 and the protrusion 461 makes the grinding rotary file 460 first be pushed away when encountering the limiting support 232, thereby avoiding the contact between the grinding rotary file 460 and the side wall of the limiting support 232, causing the wear of the limiting support 232 or the damage of the grinding rotary file 460; after the automatic grinding is completed, the excess material of the limiting support 232 part can be ground by manually grinding the limiting support 232 part or turning over the special-shaped curved structure 50 and then grinding again, thereby realizing the grinding of the entire outer edge of the special-shaped curved structure 50.

[0036] As a further optimization of the scheme of the present application, on the basis of embodiment 1, the motor mounting seat 45 includes a driving cavity 451 and a sliding cavity 452, and the driving cavity 451 is located on the side close to the spring seat 43, the driving cavity 451 is located on one side of the grinding rotary file 460 and is provided with an “L”-shaped connecting plate 450, and the “L”-shaped connecting plate 450 is respectively connected with the end surface of the sliding table 41 and the inner wall of the driving cavity 451 in sliding connection (as shown in FIG. 7, the driving cavity 451 is provided with a horizontal sliding groove corresponding to the sliding of the “L”-shaped connecting plate 450), and one end of the grinding rotary file 460 away from the grinding motor is connected with the “L”-shaped connecting plate 450 in rotation. Figure 3 、 Figure 4 As shown in FIG. 7, the driving cavity 451 is provided with a horizontal sliding groove corresponding to the sliding of the “L”-shaped connecting plate 450), and one end of the grinding rotary file 460 away from the grinding motor is connected with the “L”-shaped connecting plate 450 in rotation, avoiding the deviation of the axis of the grinding rotary file 460 during the trimming process and affecting the grinding effect.

[0039] In use, after fixing the special-shaped curved surface structural part 50, before starting the rotary motor 22, first, the spiral motor 453 is started to make the “L” shaped connecting plate 450 and the sliding plate 455 slide at the same time, so that the grinding rotary file 460 abuts against the side surface of the special-shaped curved surface structural part 50 and ensures that the attached spring 44 has a certain compression amount, and in the grinding process, the attached spring 44 makes the grinding rotary file 460 always tightly adhere to the edge of the special-shaped curved surface structural part 50, so that the grinding process is more smooth and efficient.
