Description

Technical Field

[0001] The invention relates to the technical field of building material processing equipment, and in particular to a building material cutting and end surface processing device. Background Art

[0002] Building materials are a general term for materials used in civil engineering and construction engineering; they can be divided into structural materials, decorative materials and certain special materials. In the production or use of building materials, it is often necessary to cut the building materials or process the end faces of the building materials, and sometimes both of the above processes are involved at the same time; for example, cutting the building materials into short strips and processing both ends or one end of the short strips.

[0003] The prior art usually completes the above processing in two steps. The first step is to cut the building materials into short strips; the second step is to clamp the short strips to the milling machine for end surface processing. In this way, each short strip of building material needs to be positioned and aligned when clamped, which has the disadvantages of cumbersome operation, high labor intensity and low processing efficiency. Summary of the invention

[0004] The object of the present invention is to provide a device for cutting and end surface processing of building materials, which can reduce the operation workload of operators, thereby reducing labor intensity and improving processing efficiency.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A device for cutting and end surface processing of building materials, comprising:

[0007] A first milling mechanism includes a first tool for processing building materials and a first power source for driving the first tool;

[0008] A cutting mechanism located upstream of the first milling mechanism; the cutting mechanism comprises a third cutter for cutting building materials and a third power source for driving the third cutter;

[0009] A first clamping mechanism, which is located upstream of the cutting mechanism and is used to clamp the building material; the first clamping mechanism moves back and forth along the conveying direction of the building material under the drive of the fourth power source;

[0010] The first positioning mechanism is located upstream of the cutting mechanism, and its main body is composed of a first chuck; the first claw of the first chuck is provided with a rotating member, the outer contour of the rotating member is circular or spherical, constituting a limit for the building materials, and the rotation direction of the rotating member is tangent to the conveying direction of the building materials.

[0011] Optionally, a second milling mechanism, a second positioning mechanism and a second clamping mechanism are provided downstream of the first milling mechanism; the second milling mechanism includes a second tool for processing building materials and a second power source for driving the second tool; the second positioning mechanism has the same structure as the first positioning mechanism, and the second clamping mechanism has the same structure as the first clamping mechanism.

[0012] Optionally, the rotating member is a bearing, an inner hole of the bearing is connected to the first claw, and an outer periphery of the bearing limits the building material.

[0013] Optionally, the first claw is provided with mounting blocks on both sides of the bearing, the mounting blocks have pin holes and are adapted to the plug, and the inner hole of the bearing is connected to the plug; an enlarged cap is provided at one end of the plug, and a threaded section is provided at the other end and is adapted to the nut.

[0014] Optionally, the pin hole and the inner hole of the bearing are both configured to be square, and the portion of the latch corresponding to the bearing and the pin hole is configured to be a matching prismatic structure.

[0015] Optionally, the first chuck is an electric three-jaw chuck or a pneumatic three-jaw chuck.

[0016] Optionally, the main body of the first clamping mechanism is composed of a second chuck, the second chuck is an electric three-jaw chuck or a pneumatic three-jaw chuck, and the first chuck is coaxial with the second chuck.

[0017] Optionally, the first chuck is a four-jaw chuck.

[0018] Optionally, the first clamping mechanism includes two clamping plates symmetrically arranged on both sides of the building material, and the two clamping plates are driven by a fifth power source to move closer to or farther away from each other to clamp or release the building material; a pressure sensor is provided on the clamping surface of the clamping plate.

[0019] The working principle of the present invention is as follows: the building material is passed through the through hole in the center of the first chuck, and the position of the first clamping claw is adjusted so that the outer contour of the rotating part abuts against the surface of the building material to position the building material. Then the first clamping mechanism is clamped to clamp the building material, and then the downstream end face of the building material is processed by the first milling mechanism, and finally the building material is cut by the cutting mechanism. After the building material is cut, the first clamping mechanism is released from the building material and driven by the fourth power source to move upstream; then the first clamping mechanism is re-clamped to clamp the building material and driven by the fourth power source to move the building material downstream; then the first milling mechanism and the cutting mechanism are used to perform the next round of end face processing and cutting on the building material. This is repeated to cut the building material into short strips of building material, and the processing of the ends of the short strips of building material is completed at the same time.

[0020] It can be seen that the beneficial effects of the present invention are: the first clamping mechanism and the first positioning mechanism are independent of each other, and the first clamping mechanism can keep the building material positioned when it moves back and forth and transports the building material; the downstream end face of the building material is processed before each cutting, and the end face processing and cutting are staggered, and only one positioning is required to complete the multi-section cutting of the building material and the end face processing of each short strip of building material. The workload of the operator is reduced, the labor intensity is reduced, and the processing efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The following is combined with Figures 1 to 13 Embodiments of the present invention are described in detail.

[0040] An embodiment of the present invention provides a device for cutting and end surface processing of building materials, and the device for cutting and end surface processing of building materials comprises:

[0041] The first milling mechanism 1 includes a first tool 11 for processing building materials and a first power source for driving the first tool 11; it should be understood that, according to different actual needs, the first tool 11 can use different types of milling cutters to perform milling or drilling processing on the end surface of the building material. The first power source includes a first motor 12 for driving the first tool 11 to rotate, a first screw or a first linear motor for driving the first motor 12 to move in the X-axis direction, a second screw or a second linear motor for driving the first screw or the first linear motor to move in the Y-axis direction, and a third screw or a third linear motor for driving the second screw or the second linear motor to move in the Z-axis direction. In addition, the first power source is also adapted with a controller, and the first power source can also be started and stopped and the stroke controlled manually.

[0042] The cutting mechanism 2 is located upstream of the first milling mechanism 1; the cutting mechanism 2 includes a third tool 21 for cutting building materials and a third power source for driving the third tool 21; it should be understood that the third tool 21 is generally a cutter disc structure. The third power source includes a third motor for driving the third tool 21 to rotate, and a lead screw or a linear motor for driving the third motor and the third tool 21 to approach or move away from the building materials. In addition, when installing the building materials, the third tool 21 can be blocked in the conveying direction of the building materials, so that the end of the building materials is against the surface of the third tool 21, thereby positioning the initial position of the building materials in the conveying direction. Then, the third tool 21 is reset, and the first clamping mechanism 3 drives the building materials to move downstream once, so that the downstream end surface of the building materials can be processed by the first milling mechanism 1. In addition, a non-contact position sensor for detecting whether the downstream end of the building materials reaches the milling position can also be provided.

[0043] The first clamping mechanism 3 is located upstream of the cutting mechanism 2 and is used to clamp the building materials. The first clamping mechanism 3 moves back and forth along the conveying direction of the building materials under the drive of the fourth power source 31. It should be understood that the fourth power source 31 is usually a screw or linear motor adapted to a controller. The length of the back and forth movement of the first clamping mechanism 3 is quantitatively controlled by the controller or manually, so that the repeated quantitative conveying of the building materials can be achieved. In addition, the repeated quantitative conveying of the building materials can also be achieved by the cooperation of the non-contact position sensor and the controller of the fourth power source 31.

[0044] The first positioning mechanism 4 is located upstream of the cutting mechanism 2, and its main body is composed of a first chuck 41; the first claw 42 of the first chuck 41 is provided with a rotating member 43, the outer contour of the rotating member 43 is circular or spherical, constituting a limit for the building material, and the rotation direction of the rotating member 43 is tangential to the conveying direction of the building material. It should be understood that the outer contour of the rotating member 43 abuts against the side of the building material, and when the building material moves in the conveying direction, the rotating member 43 will rotate accordingly, so that the building material remains positioned during the conveying process.

[0045] The following further describes the implementation of the present invention. The building material is passed through the through hole in the center of the first chuck 41, and the position of the first claw 42 is adjusted so that the outer contour of the rotating member 43 is against the surface of the building material to position the building material. Then, the first clamping mechanism 3 is clamped to clamp the building material, and then the downstream end face of the building material is processed by the first milling mechanism 1, and finally the building material is cut by the cutting mechanism 2. After the building material is cut, the first clamping mechanism 3 is released from the building material and moved upstream under the drive of the fourth power source 31; then, the first clamping mechanism 3 is re-clamped to clamp the building material and driven to move downstream under the drive of the fourth power source 31; then, the first milling mechanism 1 and the cutting mechanism 2 are used to perform the next round of end face processing and cutting on the building material. This is repeated to cut the building material into short strips of building material, and the processing of the ends of the short strips of building material is completed at the same time. The first clamping mechanism 3 and the first positioning mechanism 4 of the present invention are independent of each other, and can keep the building materials positioned when the first clamping mechanism 3 moves back and forth and transports the building materials; the downstream end face of the building materials is processed before each cutting, and the end face processing and cutting are performed alternately, and only one positioning is required to complete the multi-section cutting of the building materials and the end face processing of each short strip of building materials, thereby reducing the workload of operators, reducing labor intensity, and improving processing efficiency.

[0046] In the embodiment given in the present application, a second milling mechanism 5, a second positioning mechanism 6 and a second clamping mechanism 7 are provided downstream of the first milling mechanism 1; the second milling mechanism 5 includes a second tool 51 for processing building materials and a second power source for driving the second tool 51; the second positioning mechanism 6 has the same structure as the first positioning mechanism 4, and the second clamping mechanism 7 has the same structure as the first clamping mechanism 3. It should be understood that the second tool 51 can be a milling cutter or a tap to mill or tap the end face of the building material. The second power source includes a second motor 52 for driving the second tool 51 to rotate, a fourth screw or a fourth linear motor for driving the second motor 52 to move in the X-axis direction, a fifth screw or a fifth linear motor for driving the fourth screw or the fourth linear motor to move in the Y-axis direction, and a sixth screw or a sixth linear motor for driving the fifth screw or the fifth linear motor to move in the Z-axis direction. In addition, the second power source is also adapted with a controller, and the second power source can also be started and stopped and the stroke controlled manually. In addition, when the building material is relatively thick and needs to be processed into an internal thread with a larger inner diameter, the first tool 11 can also be directly set as a milling cutter for milling the internal thread, and the internal thread can be directly milled at the end of the building material through the first milling mechanism 1; at this time, there is no need to process the internal thread at the end of the building material through the second milling mechanism 5.

[0047] In the embodiment given in the present application, when it is necessary to process a threaded hole at one end of a short strip of building material, the second milling mechanism 5 is arranged downstream of the second positioning mechanism 6 and the second clamping mechanism 7; first, a light hole is processed on the downstream end face of the building material by the first milling mechanism 1, and then the building material is driven to continue to move downstream by the first clamping mechanism 3, so that the building material passes through the second positioning mechanism 6, and then a short strip of building material is cut from the building material by the cutting mechanism 2, and then the cut short strip of building material is moved to the second milling mechanism 5 by the second clamping mechanism 7, the second tool 51 is a tap or a milling cutter for milling internal threads, and the light hole of the short strip of building material is processed into a threaded hole by the second milling mechanism 5.

[0048] In the embodiment given in the present application, when both cut end surfaces of a short strip of building material need to be milled, the second milling mechanism 5 is arranged upstream of the second positioning mechanism 6 and the second clamping mechanism 7; the downstream end surface of the building material is first milled by the first milling mechanism 1, and then the building material is driven to continue to move downstream by the first clamping mechanism 3, so that the building material passes through the second positioning mechanism 6, and then a short strip of building material is cut from the building material by the cutting mechanism 2, and finally the cut short strip of building material is fixed by the second clamping mechanism 7, and the upstream end surface of the short strip of building material is milled by the second milling mechanism 5. In addition, two sets of second milling mechanisms 5 can be set, and they are arranged in the order of second milling mechanism 5, second positioning mechanism 6, second clamping mechanism 7, and second milling mechanism 5 from upstream to downstream; first, the first milling mechanism 1 processes the downstream end face of the building material before cutting; then, the second milling mechanism 5 located upstream processes the upstream end face of the cut short strip of building material; finally, the second milling mechanism 5 located downstream further processes the downstream end face of the cut short strip of building material. In addition, the first milling mechanism 1 and the second milling mechanism 5 can also be set to process the side face of the building material.

[0049] In the embodiment given in the present application, the rotating member 43 is a bearing, the inner hole of the bearing is connected to the first claw 42, and the outer periphery of the bearing limits the building material. It should be understood that the use of a bearing as the rotating member 43 can greatly reduce the friction force on the rotating member 43 during the rotation process, making the rotating member 43 smoother and more stable when rotating.

[0050] In the embodiment given in the present application, the first claw 42 is provided with mounting blocks 44 on both sides of the bearing, the mounting blocks 44 have pin holes 45 and are adapted to the plug pin 46, the inner hole of the bearing is connected to the plug pin 46; one end of the plug pin 46 is provided with an enlarged cap, and the other end is provided with a threaded section and is adapted to a nut. It should be understood that the bearing is assembled and connected with the first claw 42 through the plug pin 46, which is convenient for disassembly, maintenance or replacement.

[0051] In the embodiment given in the present application, the pin hole 45 and the inner hole of the bearing are both set to be square, and the portion of the latch pin 46 corresponding to the bearing and the pin hole 45 is set to be a matching prism structure. It should be understood that by setting the pin hole 45 to be square and the middle section of the latch pin 46 to be a matching prism structure, the latch pin 46 can be prevented from rotating with the rotation of the inner ring of the bearing, thereby preventing the latch pin 46 and the nut from loosening or even coming loose.

[0052] In the embodiment given in the present application, the first chuck 41 is an electric three-jaw chuck or a pneumatic three-jaw chuck. It should be understood that for building materials with circular, regular triangle, and regular hexagonal cross-sections, a self-centering electric three-jaw chuck or a pneumatic three-jaw chuck is selected as the first chuck 41, so that the building materials can be quickly centered and positioned.

[0053] In the embodiment given in the present application, the main body of the first clamping mechanism 3 is composed of a second chuck 34 , the second chuck 34 is an electric three-jaw chuck or a pneumatic three-jaw chuck, and the first chuck 41 is coaxial with the second chuck 34 .

[0054] In the embodiment given in the present application, the first chuck 41 is a four-jaw chuck. It should be understood that the four-jaw chuck is selected as the first chuck 41, which can limit and position the building materials with irregular cross-sections.

[0055] In the embodiment given in the present application, the first clamping mechanism 3 includes two clamping plates 32 symmetrically arranged on both sides of the building material. The two clamping plates 32 are driven by the fifth power source 33 to move closer or farther from each other to clamp or release the building material; the clamping surface of the clamping plate 32 is provided with a pressure sensor. It should be understood that the fifth power source 33 is usually a cylinder or hydraulic cylinder adapted with a controller. The pressure sensor can detect the pressure applied between the clamping plate 32 and the building material, and feed it back to the controller of the fifth power source 33, so as to automatically adjust the driving of the clamping plate 32 by the fifth power source 33, so as to avoid the situation where the pressure of the two clamping plates 32 is one high and one low, or one is not, so as to better clamp the building material and avoid deformation of the building material due to uneven force on both sides. In addition, the operator can also manually adjust the fifth power source 33 that drives the clamping plate 32 according to the pressure value detected and displayed by the pressure sensor. In addition, when the first clamping mechanism 3 is configured to be composed of two clamping plates 32, it can cooperate with the first chuck 41 of a four-jaw chuck structure, and can also cooperate with the first chuck 41 of a three-jaw chuck structure.

[0056] Although specific embodiments of the present invention are described above, those skilled in the art should understand that various changes or modifications may be made to these embodiments without departing from the principles and essence of the present invention, and these changes and modifications are all within the scope of protection of the present invention.
