Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a tooling for aligning and clamping E-type bolts. Background Technology

[0002] like Figure 1 The image shows an E-type bolt, which is used in scraper conveyors. The E-type bolt and nut are installed on both sides of the scraper chain, and the scraper is placed in the central trough. The scraper chain drags the scraper along the central trough to transport the ore.

[0003] Because the E-bolt is a cast, irregularly shaped part, after casting, the three cylinders of the E-bolt need to be machined to be round and then threaded before it can be used with a matching nut. Before machining the three cylinders of the E-bolt, it needs to be aligned and clamped to be processed into a qualified product. However, the bottom surface of the E-bolt is a V-shaped bevel and a circular arc surface. Using existing fixtures, alignment and clamping during the processing is difficult. Since most existing fixtures consist of two flat clamping blocks that are brought close together to clamp the E-bolt, there is always a problem that the cylinders are not machined to the required roundness due to improper alignment or unreasonable alignment position during clamping, which leads to product defects. Summary of the Invention

[0004] In view of this, it is necessary to provide an E-type bolt alignment and clamping fixture that can align the E-type bolt before clamping and then clamp the aligned E-type bolt for turning and threading the cylinder.

[0005] An E-type bolt alignment and clamping fixture includes a base plate, a support assembly, an alignment assembly, and a clamping assembly. All three assemblies are mounted on the base plate. There are two sets of support assemblies, located on either side of the alignment assembly. There are also two sets of clamping assemblies, located on either side of the two support assemblies. The two sets of support assemblies support and lift the E-type bolt. The alignment assembly vertically clamps the middle column of the E-type bolt, thus aligning it. The two sets of clamping assemblies clamp both ends of the E-type bolt, ensuring that the E-type bolt placed in the fixture is first aligned and then clamped for accurate machining of the three cylinders.

[0006] Preferably, the support assembly includes a support base, a support body, a support arm, and a support column. The support base is mounted on a base plate, and the support body is mounted on the support base. The support body has a first receiving hole and a second receiving hole, both of which are vertically positioned on the support body. The support arm is positioned in the first receiving hole, and a first spring is also provided in the first receiving hole. The upper end of the first spring contacts the lower end of the support arm, and the lower end of the first spring contacts the support base. The support column is positioned in the second receiving hole, and a second spring is also provided in the second receiving hole. The upper end of the second spring contacts the lower end of the support column, and the lower end of the second spring contacts the support base. A lifting part is provided at the top of the support arm, and the inner surface of the lifting part that contacts the E-bolt matches the outer surface of the bottom of the E-bolt.

[0007] Preferably, the alignment component includes a first support base, a second support base, a first connecting arm, a second connecting arm, a first clamping arm, a second clamping arm, and a connector. The first and second support bases are spaced apart on the base plate. The first support base and the first end of the first connecting arm are connected by a first pivot. The second support base and the first end of the second connecting arm are connected by a second pivot. The second end of the first connecting arm and the middle position of the first clamping arm are connected by a third pivot. The second end of the second connecting arm and the middle position of the second clamping arm are connected by a fourth pivot. The bottom end of the first clamping arm and the connector are connected by a fifth pivot. The bottom end of the second clamping arm and the connecting piece are connected via a sixth rotating shaft. The lower end of the connecting piece is connected to an external power source. The first support, the first connecting arm, and the first clamping arm are symmetrically arranged with the second support, the second connecting arm, and the second clamping arm, respectively. The external power source pushes the connecting piece upward, which in turn pushes the lower ends of the first and second clamping arms upward. The first connecting arm, pushed by the first clamping arm, rotates outward around the first rotating shaft, and the second connecting arm, pushed by the second clamping arm, rotates outward around the second rotating shaft. The upward push of the connecting piece causes the lower ends of the first and second clamping arms to move upward. Under the combined action of the lower end of the second clamping arm, the first connecting arm rotating outward and pulling the middle of the first clamping arm, and the second connecting arm rotating outward and pulling the middle of the second clamping arm, both the upper ends of the first and second clamping arms rotate outward and open. The power end pulls the connecting piece downward, which in turn pulls the lower ends of the first and second clamping arms downward. The first connecting arm, pulled by the first clamping arm, rotates inward around the first axis, and the second connecting arm, pulled by the second clamping arm, rotates inward around the second axis. The downward pull of the connecting piece... Under the combined action of the lower ends of the clamping arm and the second clamping arm, as well as the first connecting arm rotating inward and pulling the middle of the first clamping arm, the upper ends of the first clamping arm and the upper ends of the second clamping arm rotate inward and gradually approach the middle post of the E-bolt. At the same time, since the first support, the first connecting arm, and the first clamping arm are symmetrically arranged with the second support, the second connecting arm, and the second clamping arm, the first clamping arm and the second clamping arm clamp the middle post of the E-bolt, so that the middle post of the E-bolt is in a vertical state and thus achieves alignment.

[0008] Preferably, both the first clamping arm and the second clamping arm are C-shaped structures. The upper end of the first clamping arm is provided with a first arc clamping surface, and the upper end surface of the second clamping arm is provided with a second arc clamping surface. The middle post of the E-bolt is clamped and fixed by the first arc clamping surface and the second arc clamping surface moving towards the middle post of the E-bolt simultaneously.

[0009] Preferably, the clamping assembly includes a base, a first slider, a second slider, a first clamping member, and a second clamping member. The base is mounted on a bottom plate, and a guide groove is provided inside the base, penetrating the left and right ends of the base. The first slider and the second slider are symmetrically arranged in the guide groove of the base and move closer to or further away from each other along the guide groove. The first clamping member is disposed on the first slider, and the second clamping member is disposed on the second slider. The first clamping member and the second clamping member are arranged in a mirror symmetrical manner.

[0010] Preferably, the clamping assembly further includes a traction block, the vertical cross-section of which is an isosceles trapezoid. A dovetail tenon is provided on each of the two sides of the traction block. The inner side of the first slider relative to the second slider is an inclined surface, the inclination of which matches the inclination of the traction block's side surface. A first dovetail groove is provided on the inclined surface of the first slider. The inner side of the second slider relative to the first slider is an inclined surface, the inclination of which matches the inclination of the traction block's side surface. A second dovetail groove is provided on the inclined surface of the second slider. A receiving cavity is provided extending from the upper surface to the lower surface of the base. The traction block self-receives... The lower end of the cavity is inserted, and the dovetail tenons on both sides of the traction block are respectively embedded in the first dovetail groove and the second dovetail groove. The lower end of the traction block is connected to the external hydraulic jack. The external hydraulic jack pushes the traction block to move up and down along the accommodating cavity. During the upward movement of the traction block, the first slider and the second slider are pushed to move away from each other along the guide groove. During the downward movement of the traction block, the first slider and the second slider are pulled to move closer to each other along the guide groove. During the movement of the first slider and the second slider closer to each other along the guide groove, the first clamping member and the second clamping member move closer to each other to clamp the two ends of the E-bolt.

[0011] Preferably, the E-type bolt alignment and clamping fixture further includes a limiting component, which includes a first limiting member and a second limiting member. The first limiting member and the second limiting member are disposed on the base plate and are located on the outside of the two sets of clamping components, respectively. The upper end of the first limiting member is provided with a first limiting end, which extends towards the upper end of the adjacent clamping component. The upper end of the second limiting member is provided with a second limiting end, which extends towards the upper end of the adjacent clamping component.

[0012] Preferably, the first limiting member is provided with a first fixing groove, the extension direction of the groove opening of the first fixing groove is consistent with the extension direction of the first limiting end, and the second limiting member is provided with a second fixing groove, the extension direction of the groove opening of the second fixing groove is consistent with the extension direction of the second limiting end. The distance between the first limiting member and the second limiting member can be adjusted through the first fixing groove and the second fixing groove, so that E-type bolts of different specifications are placed after being limited by the first limiting member and the second limiting member, which facilitates the alignment and clamping of the component.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the E-bolt is supported and lifted by two sets of support components and the E-bolt column is placed upward. After the alignment component clamps the middle column of the E-bolt vertically, the E-bolt is aligned. Then, the two sets of clamping components clamp the two ends of the E-bolt respectively, so that the E-bolt placed in the above tooling is aligned and then clamped to facilitate the accurate processing of the three cylinders.

Detailed Implementation

[0025] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0026] Please see Figures 1 to 10 The E-bolt alignment and clamping fixture includes a base plate 10, a support assembly 20, an alignment assembly 30, and a clamping assembly 40. The support assembly 20, alignment assembly 30, and clamping assembly 40 are all mounted on the base plate 10. There are two sets of support assemblies 20, located on either side of the alignment assembly 30. There are also two sets of clamping assemblies 40, located on either side of the two support assemblies 20. The two sets of support assemblies 200 support and lift the E-bolt 200. The alignment assembly 30 clamps the middle column of the E-bolt 200 vertically, thus aligning the E-bolt 200. The two sets of clamping assemblies 40 clamp the two ends of the E-bolt 200, so that the E-bolt 200 placed in the fixture is first aligned and then clamped to facilitate accurate machining of the three cylinders.

[0027] Furthermore, the support assembly 20 includes a support base 21, a support body 22, a support arm 23, and a support column 24. The support base 21 is mounted on the base plate 10, and the support body 22 is mounted on the support base 21. The support body 22 is provided with a first receiving hole 221 and a second receiving hole 222, both of which are vertically arranged on the support body 22. The support arm 23 is disposed in the first receiving hole 221, and a first spring 223 is also disposed in the first receiving hole 221. The upper end of the support arm 23 contacts the lower end of the support arm 23, the lower end of the first spring 223 contacts the support base 21, the support column 24 is disposed in the second receiving hole 222, and the second receiving hole 222 is also disposed in the second receiving hole 224. The upper end of the second spring 224 contacts the lower end of the support column 24, and the lower end of the second spring 224 contacts the support base 21. The top end of the support arm 23 is provided with a lifting part 231, and the inner side of the lifting part 231 that contacts the E-bolt 200 matches the outer side of the bottom of the E-bolt 200. The bottom of the E-bolt 200 is placed on the lifting part 231 and the support column 24. After the two lifting parts 231, the support column 24, the first spring 223 and the second spring 224 of the two sets of support components 20 lift the E-bolt 200, so that the three cylinders of the E-bolt 200 are all facing upward, so that the alignment component 30 can clamp the middle cylinder and fix the middle cylinder vertically.

[0028] Furthermore, the alignment component 30 includes a first support base 31, a second support base 32, a first connecting arm 33, a second connecting arm 34, a first clamping arm 35, a second clamping arm 36, and a connector 37. The first support base 31 and the second support base 32 are spaced apart on the base plate 10. The first ends of the first support base 31 and the first connecting arm 33 are connected by a first rotating shaft 301. The first ends of the second support base 32 and the second connecting arm 34 are connected by a second rotating shaft 302. The second end of the first connecting arm 33 and the middle position of the first clamping arm 35 are connected by a third rotating shaft 303. The second end of the second connecting arm 34 and the middle position of the second clamping arm 36 are connected by a fourth rotating shaft 304. The bottom end of the first clamping arm 35 and the connector 37 are connected by a third rotating shaft 304. The fifth pivot 305 is connected, the bottom end of the second clamping arm 36 and the connecting piece 37 are connected by the sixth pivot 306, and the lower end of the connecting piece 37 and the power end are connected by the seventh pivot 307. The power end is specifically a hydraulic cylinder. The first support base 31, the first connecting arm 33, and the first clamping arm 35 are symmetrically arranged with the second support base 32, the second connecting arm 34, and the second clamping arm 36, respectively. The power end pushes the connecting piece 37 to move upward, and the upward movement of the connecting piece 37 pushes the lower ends of the first clamping arm 35 and the lower ends of the second clamping arm 36 to move upward. After being pushed by the first clamping arm 35, the first connecting arm 33 rotates outward around the first pivot 301, and the second connecting arm 34 rotates outward around the second pivot 302 after being pushed by the second clamping arm 36. The upward pushing of the connector 37 pushes the lower ends of the first clamping arm 35 and the second clamping arm 36, while the outward rotation of the first connecting arm 33 pulls the middle of the first clamping arm 35, and the outward rotation of the second connecting arm 34 pulls the middle of the second clamping arm 36, causing the upper ends of the first clamping arm 35 and the upper ends of the second clamping arm 36 to both rotate outward and open. The power end pulls the connector 37 downward, which in turn pulls the lower ends of the first clamping arm 35 and the second clamping arm 36 downward. The first connecting arm 33, pulled by the first clamping arm 35, rotates inward around the first pivot 301, and the second connecting arm 34, pulled by the second clamping arm 36, rotates inward around the second pivot 302. The combined effect of the downward pulling of the lower ends of the first clamping arm 35 and the second clamping arm 36, the inward rotation of the first connecting arm 33 pulling the middle of the first clamping arm 35, and the inward rotation of the second connecting arm 34 pulling the middle of the second clamping arm 36, causes the upper ends of the first clamping arm 35 and the upper ends of the second clamping arm 36 to rotate inward and gradually approach the middle post of the E-bolt 200. At the same time, since the first support base 31, the first connecting arm 33, and the first clamping arm 35 are symmetrically arranged with the second support base 32, the second connecting arm 34, and the second clamping arm 36, the first clamping arm 35 and the second clamping arm 36 clamp the middle post of the E-bolt 200, so that the middle post of the E-bolt 200 is in a vertical state and thus achieves alignment.

[0029] Specifically, both the first clamping arm 35 and the second clamping arm 36 have a C-shaped structure. The upper end of the first clamping arm 35 is provided with a first arc clamping surface 351, and the upper end of the second clamping arm 36 is provided with a second arc clamping surface 361. By having the first arc clamping surface 351 and the second arc clamping surface 361 move towards the middle post of the E-bolt 200 simultaneously, the middle post of the E-bolt 200 is clamped and fixed to achieve the purpose of alignment.

[0030] Furthermore, the clamping assembly 40 includes a base 41, a first slider 42, a second slider 43, a first clamping member 44, and a second clamping member 45. The base 41 is mounted on the base plate 10. A guide groove 411 is provided in the base 41, which penetrates the left and right ends of the base 41. The first slider 42 and the second slider 43 are symmetrically arranged in the guide groove 411 of the base 41 and move closer or further apart from each other along the guide groove 411. The first clamping member 44 is disposed on the first slider 42, and the second clamping member 45 is disposed on the second slider 43. The first clamping member 44 and the second clamping member 45 are mirror-symmetrically arranged.

[0031] Furthermore, the clamping assembly 40 also includes a traction block 46, the vertical cross-section of which is an isosceles trapezoid. A dovetail tenon 461 is provided on each of the two sides of the traction block 46. The inner side of the first slider 42 relative to the second slider 43 is an inclined surface, the inclination of which matches the inclination of the side of the traction block 46. A first dovetail groove 421 is provided on the inclined surface of the first slider 42. The inner side of the second slider 43 relative to the first slider 42 is an inclined surface, the inclination of which matches the inclination of the side of the traction block 46. A second dovetail groove 431 is provided on the inclined surface of the second slider 43. A receiving cavity 412 is provided through the base 41 from the upper surface to the lower surface. The traction block 46 is self-accommodating... The lower end of the cavity 412 is inserted, and the dovetail tenons 461 on both sides of the traction block 46 are respectively embedded in the first dovetail groove 421 and the second dovetail groove 431. The lower end of the traction block 46 is connected to the external hydraulic jack. The external hydraulic jack pushes the traction block 46 to move up and down along the accommodating cavity 412. During the upward movement of the traction block 46, the first slider 42 and the second slider 43 are pushed to move away from each other along the guide groove 411. During the downward movement of the traction block 46, the first slider 42 and the second slider 43 are pulled closer to each other along the guide groove 411. During the movement of the first slider 42 and the second slider 43 closer to each other along the guide groove 411, the first clamping member and the second clamping member move closer to each other to clamp the two ends of the E-bolt.

[0032] Furthermore, the E-bolt alignment and clamping fixture also includes a limiting component, which includes a first limiting member 50 and a second limiting member 60. The first limiting member 50 and the second limiting member 60 are disposed on the base plate 10. The first limiting member 50 and the second limiting member 60 are respectively located on the outside of the two sets of clamping components 40. The upper end of the first limiting member 50 is provided with a first limiting end 51, which extends towards the upper end of the adjacent clamping component 40. The upper end of the second limiting member 60 is provided with a second limiting end 61, which extends towards the upper end of the adjacent clamping component 40.

[0033] Furthermore, a first fixing groove 52 is provided on the first limiting member 50, and the extension direction of the groove opening of the first fixing groove 52 is consistent with the extension direction of the first limiting end 51. A second fixing groove 62 is provided on the second limiting member 60, and the extension direction of the groove opening of the second fixing groove 62 is consistent with the extension direction of the second limiting end 61. The distance between the first limiting member 50 and the second limiting member 60 can be adjusted through the first fixing groove 52 and the second fixing groove 62, so that after E-type bolts 200 of different specifications are placed on the support assembly 20, they are jointly limited by the first limiting member 50 and the second limiting member 60, making it easier for the alignment assembly 30 to clamp them.
