Description

Technical Field

[0001] The invention relates to the technical field of machine tool assembly, and in particular to an auxiliary assembly grinding jig for granite beams and columns and a use method thereof. Background Art

[0002] Granite is a very hard and stable material with excellent shock resistance. It is not easily affected by external changes such as temperature and humidity, thus ensuring stability and precision during long-term use. In addition, in the field of machine tools, its high damping characteristics also make the granite bed have good shock absorption capabilities. The use of granite columns and beams can reduce the impact of machine tools when they are impacted or vibrated, ensuring processing quality and precision.

[0003] However, granite cannot be cast like cast iron, and can only be made into simpler components through cutting and grinding. For example, when components such as machine tool bases, columns, and beams need to be connected to form a whole, they need to be bolted together to form a whole bed.

[0004] Due to the limitation of grinding accuracy of the joint surfaces of the beam and column, and the independent processing of granite beams and columns, the errors existing in the processing of granite beams and columns will also cause error accumulation during assembly, and due to the limitation of surface treatment process, the granite beams and columns will not fit well during assembly, resulting in the granular quality on the contact surface between the granite bed components, which is difficult to observe with the naked eye, affecting the assembly accuracy and contact stiffness, and thus affecting the contact stiffness and position accuracy between the components.

[0005] Therefore, it is necessary to develop an auxiliary assembly grinding jig and a method for using granite beams and columns to solve the above problems. Summary of the invention

[0054] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] Embodiment 1, a granite beam, column auxiliary assembly grinding jig, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown.

[0056] It includes an assembly frame 1, a limit frame 2, a stand 3, a movable mechanism 4 and a driving mechanism 5. There are two assembly frames 1, each of which is a U-shaped structure with an assembly hole. The two assembly frames 1 can be respectively mounted on both sides of the granite column through the U-shaped structure, and can be accurately assembled on both sides of the granite column through the assembly hole structure of the assembly frame 1.

[0057] A limiting frame 2 is fixedly connected to the lower side of the planar structure of the assembly frame 1, and a vertical frame 3 is fixedly connected to the upper side of the limiting frame 2. A movable mechanism 4 is arranged on the upper side of the assembly frame 1, and the movable mechanism 4 is used to be installed on both sides of the granite beam. The movable mechanism 4 has no connection and contact relationship with the assembly frame 1. A driving mechanism 5 is arranged on the upper side of the planar structure of the assembly frame 1, and the driving mechanism 5 is respectively in contact with and cooperates with the adjacent movable mechanisms 4. The driving mechanism 5 is used to contact and drive the movable mechanism 4 to move forward and backward, and the limiting frame 2 is used to limit the maximum driving range of the driving mechanism 5.

[0058] like Figure 6As shown, the movable mechanism 4 includes an assembly plate 41 and a force frame 42. There are two assembly plates 41, which are respectively located above the adjacent assembly frames 1. The assembly plate 41 is a structure with assembly holes. The assembly plate 41 can be accurately installed on the two side planes of the granite beam through its assembly holes. The assembly plates 41 are fixedly connected with force frames 42 on opposite sides. The force frame 42 is a trumpet-shaped inverted U-shaped structure. The inverted U-shaped structure of the force frame 42 is used to cover the driving mechanism 5 when hoisting the granite beam column. The inner wall opening of the inverted U-shaped structure of the force frame 42 is an arc-shaped chamfered structure. The arc-shaped chamfered structure of the force frame 42 is used to compensate for the error of the hoisting displacement of the granite beam column when covering the driving mechanism 5.

[0059] When the movable mechanism 4 is in use, the assembly plate 41 can be installed on the two side surfaces of the granite beam through fasteners. When the beam is hoisted by a crane, the force frame 42 is sleeved on the upper end position of the driving mechanism 5; when a person operates the driving mechanism 5, the driving mechanism 5 will drive the force frame 42 to move forward and backward, thereby causing the beam to move forward and backward ( Figure 4 direction shown).

[0060] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the driving mechanism 5 includes an axle seat 51, a rocker arm 52 and a crank 53. The axle seats 51 are in two groups, and the axle seats 51 are fixedly connected to the opposite sides of the assembly frame 1 respectively. The axle seats 51 are rotatably connected to the rocker arms 52, and the lower sides of the rocker arms 52 are detachably connected to the cranks 53. The cranks 53 and the rocker arms 52 and their upper ends constitute a large-power arm lever structure, so that when the rocker arm 53 rotates, the upper end of the rocker arm 52 has a large torque to drive the displacement of the force frame 42; in use, the crank 53 can be installed on the lower side of the rocker arm 52. After the granite beam column is hoisted, two personnel can shake the crank 53 at the same time, so that the rocker arm 52 outputs a large torque through the axle seat 51 to drive the force frame 42 to move forward and backward.

[0061] like Figure 6 and Figure 7As shown, it also includes an anti-wear component 6, which includes a first anti-wear plate 61 and a second anti-wear plate 62. The anti-wear component 6 is used to reduce the friction loss of the rocker arm 52 and the force frame 42 of the fixture to avoid frequent replacement of components such as the force frame 42 and the rocker arm 52 that are difficult to process and have high processing costs. The first anti-wear plate 61 is detachably installed on both sides of the inner wall of the force frame 42, and the second anti-wear plate 62 is detachably installed on both sides of the upper end of the rocker arm 52. The first anti-wear plate 61 and the second anti-wear plate 62 are both made of anti-friction alloy, and the mutual contact surfaces of the first anti-wear plate 61 and the second anti-wear plate 62 are both surface polished. The materials of the first anti-wear plate 61 and the second anti-wear plate 62 can be wear-resistant steel, high manganese steel series, chrome cast iron series, alloy steel, etc.

[0062] During use, the first anti-wear sheet 61 can be installed on the inner wall of the force frame 42 by fasteners, and the second anti-wear sheet 62 can be installed on the upper end of the rocker arm 52 by fasteners. When the first anti-wear sheet 61 and the second anti-wear sheet 62 are in contact and driven with a large torque, the first anti-wear sheet 61 and the second anti-wear sheet 62 will rub against each other, avoiding the loss of high-cost components caused by direct contact and friction between the force frame 42 and the rocker arm 52. The detachable installation of the first anti-wear sheet 61 and the second anti-wear sheet 62 also facilitates timely replacement, which can reduce the working cost of the jig in the inevitable friction loss.

[0063] During use, the above structure can be used to install the movable mechanism 4 on the planes on both sides of the granite beam, and then install the assembly frame 1 on both sides of the granite column through fasteners. Then, remove impurities such as oil, dust, etc. on the surface of the beam and accessories to ensure the cleanliness of the assembly surface. Then, the granite beam is hoisted onto the granite column by a crane, and red lead powder is applied to the surface of the granite beam in contact with the column. Then, the granite beam is placed on the upper side of the granite column for contact, so that the movable mechanism 4 and the driving mechanism 5 are in contact and cooperate. At this time, two personnel can be arranged to synchronously operate the driving mechanism 5 respectively, so that the driving mechanism 5 runs synchronously to drive the movable mechanism 4 to move synchronously in the forward and backward directions, thereby driving the granite beam to move forward and backward on the granite column, so that the contact position of the granite beam and the column is repeatedly ground by red lead powder.

[0064] During the above process, the limit frame 2 will limit the maximum displacement range of the driving mechanism 5 to prevent the crossbeam from overturning due to the difficulty in estimating the displacement; after grinding for about 1-2 minutes, the crossbeam can be lifted by a crane to observe the red lead powder on the contact surface of the crossbeam. When the contact area is not less than 70%, the mutual grinding process is completed and the joint surface between the crossbeam and the column is cleaned; in this way, red lead powder is used as the grinding medium to grind the granite crossbeam and the column to be assembled with each other, so that the surface bonding degree between the granite crossbeam and the column can be higher, avoiding the errors caused by the separate production and surface grinding of the granite crossbeam and the column, and can improve the geometric accuracy and contact surface stiffness of the crossbeam and the column.

[0065] Embodiment 2: Embodiment 2 is improved on the basis of Embodiment 1, specifically:

[0066] like Fig.11 As shown, it also includes a positioning mechanism 7, which includes a positioning plate 71, a linear positioning scale line 72, a centering mark point 73 and a marking assembly 8. The positioning mechanism 7 is used to locate the relative horizontal position and angle between the beam and the column, so as to provide a reference for personnel to timely correct the relative horizontal position and angle between the beam and the column when synchronously operating the rocker arm 52.

[0067] Specifically, a positioning plate 71 is fixedly connected to the upper side of the stand 3, and the positioning plate 71 is tilted for easy observation by personnel. The positioning plate 71 is provided with linear positioning scale lines 72 arranged in an array, and the linear positioning scale lines 72 are arranged in the front-to-back direction. A centering mark point 73 is provided at the center of the positioning plate 71, and a marking component 8 is provided on the opposite side of the assembly plate 41. The marking component 8 is used to emit light on the surface of the positioning plate 71 to determine the position of the granite beam relative to the granite column.

[0068] When the granite beam is hoisted on the granite column, the marking component 8 can be started to emit light for display on the positioning plate 71. The personnel can preliminarily adjust the position of the granite beam according to the positions of the linear positioning scale line 72 and the centering mark point 73 on the positioning plate 71, so that the positions of the granite beam and the granite column are relatively accurate. In this way, when the granite beam is driven to move forward and backward, the accuracy of the joint surface of the granite beam and the column can be improved; after driving the granite beam to move forward and backward, the offset of the beam on the column can also be determined by the offset of the light emitted by the marking component 8 on the positioning plate 71, so as to make timely position corrections.

[0069] To achieve the above-mentioned purpose, the marking component 8 includes an extension frame 81 and a laser emission module 82. There are two extension frames 81, and the extension frames 81 are fixedly connected to the opposite sides of the assembly frame 1 respectively. The other ends of the extension frames 81 are fixedly connected to the laser emission module 82. The laser emission module 82 is a combination module of a straight laser emission head and a point laser emission head.

[0070] When the marking component 8 is in use, the laser emission module 82 is started, and the laser emission module 82 will emit a straight laser line and a single-point laser on the positioning plate 71. The straight laser line emitted by the laser emission module 82 can determine the displacement offset and angular offset of the granite beam according to its position and angle on the straight positioning scale line 72, and the single-point laser line emitted by the laser emission module 82 can determine the offset direction of the granite beam according to its position on the centering mark point 73. According to the above-determined offset, personnel can timely and reasonably correct the relative position of the granite beam with respect to the granite column to improve the accuracy of the joint surface of the granite beam and the column ground against each other.

[0071] Embodiment 3: Embodiment 3 is improved on the basis of Embodiment 2, specifically:

[0072] like Fig. 9 and Fig.10 As shown, it also includes a driving reference mechanism 9, which includes a scale frame 91, a reference pointer 92 and a rotation reference component 10. The driving reference mechanism 9 is used to assist the two personnel operating the rocker arm 52 in synchronous operation during driving, so as to further improve the synchronization of the granite beam columns when grinding the joint surfaces against each other. After the synchronization is improved, the accuracy of the joint surfaces of the granite beam columns ground against each other can also be improved, and the physical strength of the personnel can also be saved.

[0073] Specifically, a scale frame 91 is fixedly connected to the lower side of the stand 3, and the scale frame 91 is a structure with digital scales engraved on the surface. Reference pointers 92 are fixedly connected to the opposite sides of the rocker arms 52, and the reference pointers 92 are respectively indicated on the adjacent scale frames 91. A rotation reference component 10 is provided at each of the stands 3, and the rotation reference component 10 is indicated on the scale frame 91. The rotation reference component 10 is used for reference when personnel operate the rocker arms 52, so as to improve the synchronization of driving by personnel operating the rocker arms 52 on both sides.

[0074] During use, when two personnel start to drive the rocker arm 52, the self-rotation reference component 10 can be started, and the two personnel can drive the rocker arm 52 according to the rotating self-rotation reference component 10, so that the rocker arm 52 drives the reference until it follows the self-rotation reference component 10, so that the personnel on both sides can drive the rocker arm 52 with auxiliary reference, avoiding the phenomenon that one side of the personnel on both sides has a faster or slower speed, resulting in asymmetric front and rear displacement of the granite beam, which can further improve the synchronization of personnel operations.

[0075] like Fig.10 As shown, the rotation reference component 10 includes a reduction motor 101, a connecting rod 102, a double-fork pointer 103, a pressure sensor 104 and a contact indicator light 105. There are two reduction motors 101, and both of them are worm gear self-locking motors. The two reduction motors 101 are synchronously controlled by a servo system. The reduction motors 101 are respectively fixedly connected to the stand 3. The output shafts of the reduction motors 101 are fixedly connected to the connecting rods 102. The lower sides of the connecting rods 102 are fixedly connected to the double-fork pointers 103. The double-fork pointers 103 indicate at the adjacent scale frames 91. The double-fork pointers 103 surround the reference pointers 92 corresponding to the positions. The inner sides of the two double-fork pointers 103 are fixedly connected to the pressure sensors 104. The opposite sides of the double-fork pointers 103 are fixedly connected to the contact indicator lights 105. The contact indicator lights 105 are respectively controlled by the adjacent pressure sensors 104.

[0076] When personnel are required to drive the rocker arm 52, the servo system of the reduction motor 101 can be operated to synchronously start the control, so that the reduction motor 101 drives the connecting rod 102 and the double-fork pointer 103 to rotate synchronously and slowly in the same direction. At this time, the personnel can drive the rocker arm 52 to drive the reference pointer 92 to rotate, and the personnel can operate the rocker arm 52 to make the reference pointer 92 rotate in the double-fork pointer 103. In this way, the operators on both sides can simultaneously drive the rotation of the rocker arm 52 at a certain speed. By running the reference pointer 92 in the double-fork pointer 103, the synchronization of the operations of the personnel on both sides can be further improved. At the same time, verbal reports can also be made according to the position indicated by the reference pointer 92 on the scale frame 91; for example, if the personnel on one side operate the rocker arm 52 faster or slower than that on the other side, If the double-fork pointer 103 on this side rotates at a certain speed, the reference pointer 92 connected to the rocker arm 52 on this side will contact the pressure sensor 104 at the nearby position on this side. The pressure sensor 104 recognizes the pressure and triggers the contact indicator light 105 to which it is connected to light up, prompting the personnel on this side to pay attention to the speed and position of the rocker arm 52. If one of the pressure sensors 104 recognizes that the pressure is too high, it may indicate that the personnel on this side has not operated the rocker arm 52 or other situations have occurred, and it will also force the reduction motor 101 on this side to be unable to drive the connecting rod 102 to rotate synchronously with the other side. In this case, the reduction motors 101 on both sides will stop working. When it is difficult for the personnel on the other side to observe the operation of the personnel on the other side, they can make a judgment based on whether the reduction motor 101 drives the connecting rod 102 and the double-fork bracket.

[0077] Embodiment 4: Embodiment 4 is improved on the basis of Embodiment 3, specifically:

[0078] like Figure 3 and Figure 8 As shown, it also includes a limit mechanism 11, which includes a laser beam sensor receiving module 111, a laser beam sensor transmitting module 112 and a limit indicator light 113. The limit mechanism 11 is used to protect the rocker arm 52 and ensure smooth lifting when the granite beam is lifted onto the granite column, so as to avoid the rocker arm 52 being crushed due to lifting failure caused by failure to return to the correct position.

[0079] Specifically, Figure 3 As shown, the facing sides of the rocker arm 52 are fixedly connected with laser beam sensor receiving modules 111, and the lower side of the limit frame 2 is fixedly connected with laser beam sensor transmitting modules 112. The laser beam sensor receiving modules 111 and laser beam sensor transmitting modules 112 on each side are in a mutually facing relationship. The middle part of the rocker arm 52 is fixedly connected with a limit indicator light 113, and the limit indicator light 113 is respectively controlled by the laser beam sensor receiving modules 111 corresponding to the position.

[0080] When it is necessary to hoist the granite beam onto the granite column, you can first check whether the fixture is installed and adjusted in place, and observe whether the limit indicator light 113 is on. If the limit indicator light 113 is not on, it indicates that the rocker arm 52 is not vertical to the granite beam column. In this way, when the granite beam is hoisted, the force frame 42 cannot directly cover the upper end of the rocker arm 52, which will cause the force frame 42 to be unable to be assembled on the rocker arm 52 during the beam hoisting, and subsequent operations cannot be performed. It may also cause the rocker arm 52 to be crushed during the granite beam hoisting. At this time, before hoisting the granite beam, the rocker arm 52 needs to be rotated to make the laser beam sensor receiving module 111 and the laser beam sensor transmitting module 112 correspond to each other, so that each laser beam sensor receiving module 111 is respectively received by the laser line of the adjacent laser beam sensor transmitting module 112, and the laser beam sensor receiving module 111 respectively controls the connected limit indicator light 113 to light up, which indicates that the rocker arm 52 can be surrounded and cooperated by the force frame 42 after hoisting, avoiding the occurrence of the above-mentioned adverse situations.

[0081] Example 5, can be combined with Figure 3 and Figure 4 As shown, a method for using a grinding jig for auxiliary assembly of granite beams and columns comprises the following steps:
