[0027] Embodiment 1:
[0028] like Figures 1 to 3 As shown, the deburring fixture of the utility model includes: a base 1, a gantry bracket 2 is arranged on the base 1, and side clamping structures 3 are hinged on both sides of the gantry bracket 2; a bottom support structure 4, the bottom support structure 4 is located between the two side clamping structures 3, and the bottom support structure 4 and the side clamping structures 3 are connected by a connecting rod 5; a lifting component 6, the lifting component 6 is arranged on the base 1 and is located below the bottom support structure 4, and the lifting component 6 is used to control the bottom support structure 4 to rise so that the two side clamping structures 3 are opened, and to control the bottom support structure 4 to descend so that the two side clamping structures 3 are close to each other to clamp the pipe and rod.
[0029] See also Figure 1 , Figure 3 The bottom supporting structure 4 includes a bottom plate 41 and a supporting block 42 which are connected to each other. The supporting block 42 is an arc-shaped structure to adapt to the shape of the pipe or rod. The side of the bottom plate 41 is connected to the side clamping structure 3 through a connecting rod 5. Both ends of the connecting rod 5 are in a rotational connection relationship with the bottom plate 41 and the side clamping structure 3.
[0030] In the initial state, under the action of the lifting assembly 6, the bottom support structure 4 rises to be in the middle of the two side clamping structures 3, the two connecting rods 5 are in an "eight" shaped inclined structure, and the two side clamping structures 3 are in a state of moving away from each other to be in an open state.
[0031] When it is necessary to grind the pipe and rod, first place the pipe and rod on the arc-shaped support block 42, and then control the support block 42 to move downward through the lifting assembly 6. While the support block 42 and the bottom plate 41 move downward, the side clamping structure 3 is driven toward the middle through the connecting rod 5. When the support block 42 moves down to the predetermined position, the two side clamping structures 3 clamp the sides of the pipe and rod. At this time, the two connecting rods 5 are both in the shape of "I". Thereafter, the two ends of the clamped pipe and rod can be polished by the grinding equipment. It has the characteristics of simple structure and convenient operation. At the same time, the present application uses the method of synchronously clamping the pipe and rod by the two side clamping structures 3 to effectively improve the clamping effect of the pipe plate. By configuring the support block 42 with an arc structure, the pipe and rod can be placed in advance, reducing the problem of displacement of the pipe and rod during the rising or falling process.
[0032] In one or more embodiments, the side clamping structure 3 includes a rocker 31 hinged to the gantry bracket 2 and a contour block 32 disposed on the rocker 31 .
[0033] See also Figures 1 to 3 One end of the connecting rod 5 is rotatably mounted on the bottom plate 41, and the other end is rotatably mounted on the rocker 31. When the two profiling blocks 32 are close to each other to clamp the pipe and rod, the two connecting rods 5 are arranged in a "one" shape; when it is necessary to control the two profiling blocks 32 to move away from each other, the bottom plate 41 is controlled to move up, and the two connecting rods 5 rotatably connected to the bottom plate 41 are transformed from a "one" shape to an "eight" shape. Under the action of the connecting rod 5, the rocker 31 drives the profiling block 32 to rotate relative to the gantry bracket 2, so that the two profiling blocks 32 move away from each other and no longer clamp the pipe and rod.
[0034] In one or more embodiments, the lifting assembly 6 includes: a screw 61, which is rotatably mounted on the base 1 and is located below the bottom support structure 4, and the screw 61 is driven by a driving device 62 configured on the base 1; a slider 63, which is threadedly connected to the screw 61, and a bearing rod 64 is rotatably mounted on the top of the slider 63, and the bearing rod 64 is rotatably mounted on the bottom surface of the bottom support structure 4 at the end away from the slider 63.
[0035] See also Figures 1 to 3 The driving device 62 may be a servo motor. The driving device 62 controls the screw rod 61 to rotate, so that the slider 63 is close to or away from the bottom support structure 4, so as to increase or decrease the height of the bearing rod 64 in the vertical direction, and then realize the rise or fall of the bottom support structure 4; the screw rod 61 controls the slider 63 to move, and then controls the rise or fall of the bottom support structure 4, which has the characteristics of high height adjustment accuracy and stable structure.
[0036] In one or more embodiments, the screw rod 61 has a left-handed thread and a right-handed thread, and the slider 63 has two sliders and is respectively configured on the left-handed thread and the right-handed thread.
[0037] It should be noted that the left-handed thread and the right-handed thread are symmetrically arranged on the screw 61, and sliders 63 are arranged at the left-handed thread and the right-handed thread of the screw 61, and the two sliders 63 are rotatably connected to the bottom plate 41 through the load-bearing rod 64; when the driving device 62 controls the rotation of the screw 61, the two sliders 63 on the left-handed thread and the right-handed thread can move in opposite directions, thereby realizing the rise or fall of the bottom support structure 4; through this arrangement, the stability of the load-bearing rod 64 supporting the bottom support structure 4 can be improved, thereby improving the clamping effect of the present application on the pipe and rod materials.
[0038] In one or more embodiments, a stopper 7 is disposed above the connecting rod 5 at one end close to the bottom supporting structure 4 .
[0039] See also Figure 1 , Figure 3 , the stopper 7 moves synchronously with the connecting rod 5. When the two connecting rods 5 are in an "eight"-shaped structure, the stopper 7 does not contact the top surface of the bottom plate 41; when the bottom plate 41 descends to make the two profiling blocks 32 approach each other, the two connecting rods 5 change from the "eight"-shaped structure to the "one"-shaped structure. When the two connecting rods 5 are in an "one"-shaped structure, the two profiling blocks 32 clamp the pipe and rod. At this time, the stopper 7 is close to the top surface of the bottom plate 41. Through the limiting of the stopper 7 and the top surface of the bottom plate 41, the two connecting rods 5 can be prevented from changing from the "one"-shaped structure to the inverted "eight"-shaped structure, and then the limiting bottom plate 41 continues to move downward. Through this arrangement, the two profiling blocks 32 can be prevented from excessively clamping the pipe and rod, thereby reducing damage to the pipe and rod.
[0040] In one or more embodiments, a rubber cushion is disposed on the profiling block 32 and the bottom support structure 4. The rubber cushion is not shown in the drawings. The rubber cushion is disposed inside the arc structure of the profiling block 32 and the support block 42; the rubber cushion can reduce the damage of the steel profiling block 32 and the support block 42 to the pipe and rod.
[0041] In one or more embodiments, a friction expansion surface is formed on the surface of the rubber cushion layer. The surface of the rubber cushion layer can be configured with grooves or protrusions to form a friction expansion surface; through this arrangement, the clamping effect of the present application on the tube and rod can be improved.
[0042] In one or more embodiments, the contour block 32 is mounted on the rocker 31 for relative rotation.
[0043] Embodiment 2:
[0044] It should be noted that the second embodiment and the first embodiment use the same drawings and reference numerals, and the difference between the second embodiment and the first embodiment is only that the structure of the lifting assembly 6 is different.
[0045] In the second embodiment, the lifting assembly 6 is replaced by a driving cylinder by the screw rod 61, the driving device 62, and the bearing rod 64; the extended shaft end of the driving cylinder is connected to the bottom surface of the bottom plate 41. Through this arrangement, the structure of the present application can be further simplified and the scope of application of the present application can be improved.
[0046] Embodiment three:
[0047] It should be noted that the third embodiment and the first embodiment use the same drawings and reference numerals, and the only difference between the third embodiment and the first embodiment is the structure of the lifting assembly 6 .
[0048] In the second embodiment, the lifting assembly 6 is replaced by an elastic member consisting of a screw rod 61, a driving device 62, and a bearing rod 64; the elastic member may be a spring or a hook spring; the hook spring is used as an exemplary description below:
[0049] The two ends of the hook spring are respectively hooked on the bottom surface of the bottom plate 41 and the top surface of the base 1; in the initial state, under the action of the hook spring, the two contour blocks 32 are in a state of being close to each other, the two connecting rods 5 are in an "I" shape, and the support block 42 always has a tendency to move toward the base 1, which is the clamping state of the pipe and rod.
[0050] When it is necessary to replace the pipe and rod after grinding, the profiling blocks 32 are manually opened to both sides, and then the pipe and rod are taken out and placed on the pipe and rod to be processed. Under the action of the hook spring, the two profiling blocks 32 move closer to each other to clamp the pipe and rod; through this configuration, the structure of the lifting assembly 6 can be further simplified and the production cost of the grinding fixture can be reduced.
[0051] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
