Description

Technical Field

[0001] The present application relates to the field of mechanical processing technology, and in particular to a precision mechanical parts processing equipment. Background Art

[0002] Parts processing refers to the process of changing the appearance of parts, such as polishing and grinding the rotating surface of parts, and processing equipment is usually used to complete the above process.

[0003] Some existing processing equipment is mainly composed of a grinding mechanism and a contact mechanism. When in use, the contact mechanism extends into the hollow part of the component (the component is a hollow cylindrical structure) and expands outward, so that the contact mechanism abuts and fixes the inner wall of the component. Through this action, the component is fixed. After that, the grinding mechanism located below the component moves up and contacts the outer wall of the component. Then, the contact mechanism drives the component to rotate, and the grinding mechanism rotates at the same time, so that the surface of the component is ground and polished. Through the above actions, the processing operation of the component is realized.

[0004] However, in the above process, since the contact mechanism only applies outward pressure to the parts, and the grinding mechanism applies tangential force to the parts, the parts are prone to relative rotation with the contact mechanism during the process of grinding the parts by the grinding mechanism, resulting in different contact times between the outer surface of the parts and the grinding mechanism, thereby affecting the uniformity of the outer surface processing of the parts. Summary of the invention

[0007] Furthermore, a support is fixedly installed on the upper side of the base plate and located on the side of the side plate facing the horizontal column. One end of the horizontal column facing the motor passes through the support, and the part of the horizontal column passing through the support is rotatably connected to the support.

[0008] Furthermore, the push-pull mechanism includes a connecting rod, a sleeve, a No. 1 fixed block and a No. 1 telescopic rod. The inner side of the contact piece is symmetrically provided with a connecting rod. The outer end of the connecting rod away from the side plate is hinged and fixed to the inner side surface of the contact piece. The inner end of the connecting rod away from the side plate is hinged and fixed to the circumferential side surface of the horizontal column. The outer end of the connecting rod close to the side plate is hinged and fixed to the inner side surface of the contact piece. A sleeve is slidably sleeved on the outer side of the horizontal column and close to the side plate. The inner end of the connecting rod close to the side plate is hinged and fixed to the outer side surface of the sleeve. A No. 1 fixed block is fixedly installed on the outer side surface of the sleeve. A No. 1 telescopic rod is fixedly installed on the outer side surface of the horizontal column and at a position between the No. 1 fixed block and the side plate. The output rod of the No. 1 telescopic rod is fixedly connected to the No. 1 fixed block.

[0009] Furthermore, movable plates are fixedly mounted on both sides of the contact member in the circumferential direction.

[0010] Furthermore, movable plates are hinged on both sides of the contact piece in the circumferential direction, and elastic plates are fixedly installed on both sides of the contact piece in the circumferential direction and on the side of the movable plate facing away from the inner wall of the component. The elastic plates are made of elastic material, and the side of the elastic plate facing away from the contact piece contacts the side of the movable plate facing away from the inner wall of the component.

[0011] Furthermore, there are two axially arranged contact members and sleeves at the same circumferential position, the No. 1 fixed block and the No. 1 telescopic rod correspond to the rightmost sleeve, the No. 2 telescopic rod is fixedly installed at the lower position of the circumferential side of the horizontal column, and the No. 2 fixed block is fixedly installed on the outer side of the leftmost sleeve and at the position corresponding to the No. 2 telescopic rod, and the output rod of the No. 2 telescopic rod is fixedly connected with the No. 2 fixed block.

[0012] The cam is connected with the main body in a direction of rotation, and the cam is connected with the main body in a direction of rotation.

[0013] Furthermore, the contact member further comprises a clamping strip, the side wall of the slide groove is fixedly mounted with the clamping strip, the clamping strip and the upper side surface of the sliding member are parallel to each other, and the clamping strip and the sliding member form a sliding clamping arrangement.

[0014] This application has the following beneficial effects: The present application provides a precision mechanical parts processing equipment, which, through the arrangement of a contact piece, a movable plate and a rubber piece, when the contact piece applies outward pressure to the inner wall of the part, the movable plate drives the rubber piece to synchronously contact the inner wall of the part, so that the movable plate and the inner wall of the part squeeze and deform the rubber piece. Through the above-mentioned action, the part is subjected to outward pressure while also subjected to circumferential friction resistance applied by the rubber piece. Through this force, the probability of relative rotation between the part and the contact mechanism is reduced.

[0015] By setting the movable plate, rubber parts and elastic plates, the elastic plate is used to further squeeze the movable plate and the rubber parts, so that the contact force between the rubber parts and the inner wall of the parts is further increased. Afterwards, when the parts and the contact parts have a tendency to rotate relative to each other, the parts will drive the rubber parts and the movable plate to move outward, causing the deformed rubber parts to move toward the angle formed by the movable plate and the parts, so that the contact force between the parts and the rubber parts is further increased, thereby reducing the probability of relative rotation between the parts and the contact mechanism.

[0016] By arranging the contact piece, the movable plate, the rubber piece and the elastic plate, when the contact piece extends into the inner side of a component with a larger or smaller diameter, the contact piece and the rubber piece can both contact the inner wall of the component. Through this action, the device can adapt to components of various diameters, and when the device contacts components of various diameters, the degree of reduction in the contact area between the two is relatively low, so that the fixing effect of the device on components of various diameters is not easily affected, thereby improving the adaptability of the device.

[0017] Through the arrangement of the main body and the sliding part, the main body is used to apply outward pressure to the inner wall of the component. At the same time, the sliding part applies an axial relative thrust to the main body. Since the main body is symmetrically arranged and the main body contacts the component, the component is subjected to outward pressure and axial force at the same time. Through this force, the probability of relative rotation between the component and the contact mechanism is further reduced.

[0018] By arranging the main body, the sliding part and the rubber part, the contact force between the rubber part and the inside of the component is utilized to further fix the main body, so that when the sliding part applies an axial thrust to the main body, the main body is not easy to move, thereby making the above-mentioned axial thrust better applied to the component, thereby further reducing the probability of relative rotation between the component and the contact mechanism.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Example 1: Please refer to Figure 1-Figure 4 A precision mechanical parts processing equipment comprises a base plate 1, a side plate 2 is fixedly installed at one side position of the upper side surface of the base plate 1, a motor 3 is fixedly installed inside the side plate 2, a horizontal column 4 is arranged at one side position of the side plate 2, and one end of the horizontal column 4 facing the motor 3 is fixedly connected with the output shaft of the motor 3, a support member 5 is fixedly installed on the upper side surface of the base plate 1 and at a position on the side of the side plate 2 facing the horizontal column 4, one end of the horizontal column 4 facing the motor 3 passes through the support member 5, and the part of the horizontal column 4 passing through the support member 5 is rotatably connected with the support member 5, and contact members 6 are equidistantly arranged on the circumferential outer side of the horizontal column 4 and away from the support member 5, and the contact members 6 are arranged in an arc-shaped plate structure, and connecting rods 7 are symmetrically arranged on the inner side of the contact members 6, and the outer end of the connecting rod 7 away from the side plate 2 is hinged and fixed to the inner side surface of the contact member 6, and the inner end of the connecting rod 7 away from the side plate 2 is connected to the circumference of the horizontal column 4 It is hinged and fixed to the side, the outer end of the connecting rod 7 close to the side panel 2 is hinged and fixed to the inner side of the contact piece 6, the outer side of the horizontal column 4 and close to the side panel 2 is slidably sleeved with a sleeve 8, the inner end of the connecting rod 7 close to the side panel 2 is hinged and fixed to the outer side of the sleeve 8, the outer side of the sleeve 8 and the position between the connecting rod 7 and the side panel 2 are fixedly installed with a No. 1 fixing block 9, the outer side of the horizontal column 4 and the position between the No. 1 fixing block 9 and the side panel 2 are fixedly installed with a No. 1 telescopic rod 10 (such as a combination of an electric-controlled telescopic cylinder and an output rod in the prior art), the output rod of the No. 1 telescopic rod 10 is fixedly connected with the No. 1 fixing block 9, the outer side of the contact piece 6 is provided with a component 11, and a grinding mechanism 12 (existing technology, such as a grinding cylinder, a device for driving the grinding cylinder to rotate and lift) is fixedly installed on the upper side of the bottom plate 1 and at a position below the component 11.

[0024] When in use, the output rod of the No. 1 telescopic rod 10 is extended, and the sleeve 8 is pushed to move away from the side plate 2 through the No. 1 fixing block 9, so that the connecting rods 7 on both sides gradually approach each other, and drive the corresponding contact pieces 6 to abut and fix the inner wall of the component 11. Through this action, the component 11 is fixed. After that, the grinding mechanism 12 is moved up and contacts the outer wall of the component 11. Then, the motor 3 drives the horizontal column 4, the contact piece 6 and the component 11 to rotate. At this time, the grinding mechanism 12 rotates at the same time, so that the surface of the component 11 is ground and polished. When the processing is completed, the motor 3 and the grinding mechanism 12 stop running, and then the grinding mechanism 12 and the No. 1 telescopic rod 10 are reset, so that the above structure is reset accordingly. Finally, the component 11 is removed. Through the above actions, the processing operation of the component 11 is realized.

[0025] See also Figure 1-Figure 4 A movable plate 13 is installed on both sides of the contact member 6 in the circumferential direction. The movable plate 13 is an arc-shaped plate structure. A rubber member 14 is fixedly installed on the side of the movable plate 13 facing the inner wall of the component 11.

[0026] In the process of the contact member 6 abutting and fixing the component 11, the movable plate 13 drives the rubber member 14 to synchronously contact the inner wall of the component 11, so that the movable plate 13 and the inner wall of the component 11 squeeze and deform the rubber member 14. Through the above action, the component 11 is subjected to outward pressure while also being subjected to circumferential friction resistance exerted by the rubber member 14. Through this force, the probability of relative rotation between the component 11 and the contact member 6 is reduced.

[0027] See also Figure 1-Figure 4 A movable plate 13 is hinged on both sides of the contact piece 6 in the circumferential direction, and an elastic plate 15 is fixedly installed on both sides of the contact piece 6 in the circumferential direction and on the side of the movable plate 13 facing away from the inner wall of the component 11. The elastic plate 15 is made of elastic material, and the side of the elastic plate 15 facing away from the contact piece 6 contacts the side of the movable plate 13 facing away from the inner wall of the component 11.

[0028] The elastic plate 15 is used to further squeeze the movable plate 13 and the rubber member 14, so that the contact force between the rubber member 14 and the inner wall of the component 11 is further increased. Afterwards, when the component 11 and the contact member 6 have a tendency to rotate relative to each other, the component 11 will drive the rubber member 14 and the movable plate 13 to move outward (through the friction between the inner wall of the component 11 and the rubber member 14), so that the movable plate 13 has a tendency to rotate, and the deformed rubber member 14 moves toward the angle formed by the movable plate 13 and the component 11, so that the contact force between the component 11 and the rubber member 14 is further increased, thereby reducing the friction between the component 11 and the rubber member 14. The probability of relative rotation of the contact piece 6. In addition, when the contact piece 6 extends into the inner side of the component 11 with a larger or smaller diameter, since the movable plate 13 is arranged on both sides of the contact piece 6 and is hingedly fixed with the contact piece 6, the contact piece 6 and the rubber piece 14 can contact the inner wall of the component 11 with various diameters. Through this action, the device can adapt to components 11 with various diameters, and when the device contacts components 11 with various diameters, the degree of reduction in the contact area between the two is low, so that the fixing effect of the device on components 11 with various diameters is not easily affected, thereby improving the adaptability of the device.

[0029] Example 2: Please refer to Figure 1-Figure 6 This embodiment is a further improvement of the first embodiment, and the improvement lies in that: there are axially arranged contact members 6 and sleeves 8 at the same circumferential position, and the number of contact members 6 and sleeves 8 are both two, the No. 1 fixing block 9 and the No. 1 telescopic rod 10 correspond to the rightmost sleeve 8, and the No. 2 telescopic rod 16 (such as the combination of an electric-controlled telescopic cylinder and an output rod in the prior art) is fixedly installed at the lower position of the circumferential side of the horizontal column 4, and the No. 2 fixing block 17 is fixedly installed on the outer side of the leftmost sleeve 8 and at the position corresponding to the No. 2 telescopic rod 16, and the output rod of the No. 2 telescopic rod 16 is fixedly connected to the No. 2 fixing block 17.

[0030] When in use, the output rod of the No. 1 telescopic rod 10 is extended, and the output rod of the No. 2 telescopic rod 16 is shortened, so that the corresponding connecting rod 7 drives the corresponding contact piece 6 to abut and fix the inner wall of the component 11. Through the above action, the contact area between the component 11 and the device is increased, and the fixing effect of the component 11 is further improved.

[0031] See also Figure 1-Figure 6The contact member 6 includes a sliding member 60, a main body 61, a slide groove 62, a slider 63, a clamping strip 64 and a spring 65. The inner side surface of the sliding member 60 is hingedly fixed with the outer end of the corresponding connecting rod 7. The outer side of the sliding member 60 is slidably sleeved with the main body 61. The outer side surface of the main body 61 contacts the inner wall of the component 11. The movable plate 13 is hinged on both sides of the main body 61 in the circumferential direction. The elastic plate 15 is fixedly installed on both sides of the main body 61 in the circumferential direction. The elastic plate 15 is located at a position where the movable plate 13 faces away from the inner wall of the component 11. The outer side surface of the sliding member 60 and the inner side surface of the main body 61 corresponding to the outer side surface of the sliding member 60 are both inclined. The outer sides of the two sliding members 60 on the same axial path The opposite sides of the surfaces are inclined outward, and a slide groove 62 is opened inside the sliding member 60, and a slider 63 is arranged in the slide groove 62. The outer side of the slider 63 extends out of the slide groove 62 and is fixedly connected with the inner side surface of the main body 61. A clamping strip 64 is fixedly installed on the side wall of the slide groove 62. The clamping strip 64 is parallel to the upper side surface of the sliding member 60. The clamping strip 64 and the slider 63 form a sliding clamping arrangement. A spring 65 is arranged in the two slide grooves 62 on the same axial path. The sliders 63 in the two slide grooves 62 on the same axial path are located between the two springs 65. One end of the spring 65 is fixedly connected with the inner wall of the slide groove 62, and the other end of the spring 65 contacts the corresponding slider 63.

[0032] In the process of the connecting rod 7 driving the corresponding contact member 6 to abut and fix the component 11, the connecting rod 7 first drives the main body 61 to abut and fix the component 11 through the sliding member 60, and then the connecting rod 7 continues to drive the sliding member 60 to move outward. At this time, there is friction resistance between the rubber member 14 and the component 11, and there is outward pressure between the main body 61 and the component 11, so that the main body 61 is stationary, and the two sliding members 60 on the same axial path move relative to each other, and drive the corresponding spring 65 to squeeze the corresponding slider 63, so that the main body 61 is subjected to the thrust transmitted by the spring 65 through the slider 63. Through the above action, the component 11 is subjected to outward pressure while also subjected to relative axial thrust. Through this force, the probability of relative rotation between the component 11 and the contact member 6 is further reduced.
