Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a grooving device for house wall construction. Background Art

[0002] In the water and electricity projects of the modern construction industry, for grooving of walls, a hand-held cutting machine is generally used. Construction workers use the hand-held cutting machine to cut two slits on both sides of the groove to be opened on the wall respectively, and then use tools to knock off the cement blocks between the two cutting slits, thereby realizing the cutting and forming of a linear groove on the wall surface.

[0003] However, during the implementation of the specific embodiments of the present invention by the inventors of this application, it is found that the existing wall grooving devices still have the following deficiencies: (1) The existing wall grooving devices need to cut two slits respectively to realize the cutting and forming of the groove opening, which not only increases the working intensity of wall grooving, but also results in low grooving efficiency; (2) During the grooving operation, the depth to be grooved is generally judged by the experience of construction workers, resulting in the depth of the grooved recess being easily deviated from the construction requirements, which is not conducive to the precise control of the grooving depth; (3) After the existing wall grooving devices cut two cutting lines, tools are directly used to knock the cement between the cutting slits. Since the cement between the two cutting slits is in a complete strip shape, it is very laborious during the knocking process, which is not conducive to the improvement of the grooving operation efficiency. For this reason, we provide a grooving device for house wall construction to solve the above technical problems. Summary of the Invention

[0004] In view of the above problems, the present invention provides a grooving device for house wall construction. Through the design of a groove depth control mechanism, a linkage component, a groove line cutting disc, a cutting disc positioning mechanism, and a groove width adjustment component, it solves the problems that the existing wall grooving devices cannot cut two slits simultaneously, cannot precisely control the grooving depth, directly use tools to knock the cement between the cutting slits after cutting two cutting lines, and since the cement between the two cutting slits is in a complete strip shape, it is very laborious during the knocking process, which is not conducive to the improvement of the grooving operation efficiency.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0012] As an improvement, a grooving motor is installed on one of the ear seats, and a bearing is connected and arranged on the other ear seat. The output end of the grooving motor is connected to the connecting shaft on the hollow linkage column, and the hollow linkage column is connected and arranged inside the bearing.

[0013] As an improvement, the cutting disc positioning mechanism includes:

[0014] The first positioning component, the first positioning component includes a first positioning ring slidably sleeved on the hollow linkage column. A positioning rod is connected and arranged along the circumferential side of the first positioning ring, and a threaded structure is arranged at the front end of the positioning rod; and

[0015] The second positioning component, the second positioning component includes a second positioning ring slidably sleeved on the hollow linkage column. Positioning holes corresponding to the positioning rods one by one are arranged on the second positioning ring. The positioning rod can slide axially along the positioning hole. The groove wire cutting disc is tightly installed between the first positioning ring and the second positioning ring by connecting and arranging a fastening nut at the threaded structure.

[0016] As an improvement, the second positioning component further includes an internal thread ring that is in clearance fit with the inner wall of the hollow linkage column and cooperates with the bidirectional screw. The internal thread ring is slidably arranged along the length direction of the hollow linkage column.

[0020] A groove depth control disc, the groove depth control disc is in threaded fit with the groove depth adjusting rod, and it can move along the length direction of the groove depth adjusting rod. The distance between the groove depth control disc and the bottom of the mounting substrate is the depth of the groove to be cut.

[0021] As an improvement, a storage cavity coaxial with the groove depth adjusting rod is arranged at the bottom of the mounting substrate. An elastic element sleeved outside the groove depth adjusting rod is connected in the storage cavity.

[0022] As an improvement, an auxiliary cutting disc is arranged inside the protective housing. The auxiliary cutting disc is perpendicular to the groove line cutting disc.

[0024] The present invention has the following beneficial effects:

[0025] 1. Through the threaded fit relationship between the groove width adjusting component and the two cutting disc positioning mechanisms on the linkage component, the present invention can adjust the distance between the two groove line cutting discs arranged in parallel to make it meet the cutting forming of groove openings with different widths on the wall surface, without respectively cutting out two slits successively, thereby greatly increasing the efficiency of the grooving operation and reducing the working intensity of the grooving operation.

[0026] 2. The present invention controls the distance between the groove depth control disc and the mounting substrate, and uses the measuring scale as a reference during the grooving process. When the present invention is used to cut a slit against the wall until the groove depth control disc abuts against the mounting substrate, the distance moved by the groove depth control disc at this time is the depth of the groove cutting disc entering the wall, thereby realizing precise control of the grooving depth of the wall and greatly increasing the efficiency of the grooving operation.

[0027] 3. During the process of using the groove cutting disc to linearly move and cut the groove, at intervals, the auxiliary cutting disc is used to cut the cement between the two cut slits again, so that the cement between the two slits cut by the groove cutting disc is divided into multiple small-sized cement blocks, which is convenient for knocking and removing the cement between the two slits later. This not only greatly improves the grooving efficiency but also greatly reduces the working intensity of the grooving operators.

[0028] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

The two cutting slits cut by the two groove wire cutting discs 3 are the widths of the required grooves;

[0049] Cutting disc positioning mechanism 4, the cutting disc positioning mechanism 4 is connected and arranged on the hollow linkage column 201, and it can slide along the length direction of the hollow linkage column 201. The cutting disc positioning mechanism 4 fixes the groove wire cutting discs 3 together and is used to drive the groove wire cutting discs 3 to rotate synchronously with the hollow linkage column 201; and

[0050] Groove width adjustment assembly 5, the groove width adjustment assembly 5 is embedded and connected inside the hollow linkage column 201. The groove width adjustment assembly 5 includes a bidirectional screw 501 that is threadedly matched with the two cutting disc positioning mechanisms 4. The bidirectional screw 501 is used to drive the two cutting disc positioning mechanisms 4 to move towards each other. One end of the bidirectional screw 501 is fixed with an adjustment knob 502, and a locking ring 503 coaxial with the adjustment knob 502 is connected to the adjustment knob 502. The locking holes 504 on the locking ring 503 correspond one-to-one with the locking grooves 204 and the two are connected by a locking rod. After unlocking the locking rod from the locking ring 503, by rotating the adjustment knob 502 at one end of the bidirectional screw 501, the horizontal distance between the two cutting disc positioning mechanisms 4 can be adjusted, and further the horizontal distance between the two groove wire cutting discs 3 can be adjusted to meet the grooving construction of different width slots.

[0051] Further, a grooving motor 102 is installed on one of the ear seats, a bearing 103 is connected and arranged on the other ear seat. The output end of the grooving motor 102 is connected to a connecting shaft 205 on the hollow linkage column 201. The hollow linkage column 201 is connected and arranged inside the bearing 103. By starting the grooving motor 102, the rotation of the hollow linkage column 201 can be driven, and further the synchronous rotation of the two cutting disc positioning mechanisms 4 on the hollow linkage column 201 can be realized.

[0052] Further, the cutting disc positioning mechanism 4 includes:

[0053] The first positioning component 41, the first positioning component 41 includes a first positioning ring 411 slidably sleeved on the hollow linkage column 201, a positioning rod 412 arranged along the circumferential side of the first positioning ring 411 is connected to the first positioning ring 411, and a threaded structure 413 is arranged at the front end of the positioning rod 412; and

[0054] The second positioning component 42, the second positioning component 42 includes a second positioning ring 421 slidably sleeved on the hollow linkage column 201, positioning holes 422 corresponding to the positioning rods 412 one by one are arranged on the second positioning ring 421, the positioning rods 412 can be slidably arranged along the axial direction of the positioning holes 422, and at the same time, after the positioning rods 412 pass through the fixing holes on the groove line cutting disc 3, the groove line cutting disc 3 is tightly installed between the first positioning ring 411 and the second positioning ring 421 by connecting and arranging a fastening nut at the threaded structure 413, so as to realize the synchronous rotation cutting of the two groove line cutting discs 3 driven by the linkage component 2.

[0055] Further, the second positioning component 42 further includes an internal thread ring 423 which is in clearance fit with the inner wall of the hollow linkage column 201 and is matched with the bidirectional screw rod 501, the internal thread ring 423 can be slidably arranged along the length direction of the hollow linkage column 201, the internal thread ring 423 and the second positioning ring 421 are connected by a limiting rod 424, the limiting rod 424 can be slidably arranged along the extending direction of the guiding slideway 203, so that when the bidirectional screw rod 501 is rotated, under the thread fit of the bidirectional screw rod 501 and the two internal thread rings 423, the two cutting disc positioning mechanisms 4 can only drive the groove line cutting disc 3 to move horizontally in the same direction synchronously, and the cutting disc positioning mechanism 4 will not be driven to rotate synchronously due to the rotation of the bidirectional screw rod 501.

[0056] Further, mounting substrates 104 are connected to opposite side walls of the protective housing 101, and a groove depth control sleeve group 11 is connected to the mounting substrates 104 for accurately controlling the forward cutting depth of the groove line cutting disc 3.

[0057] A roller 1101, the roller 1101 is connected in a roller frame 1102, a measuring scale 1103 and a groove depth adjusting rod 1104 which are slidably matched with the mounting substrate 104 are fixedly connected to the roller frame 1102; when the groove line cutting disc 3 is not rotated and cut in the initial state, both the groove line cutting disc 3 and the roller 1101 just abut against the wall surface, and the roller 1101 always abuts against the wall surface and moves during the process of cutting a groove by using the groove line cutting disc 3;

[0058] In-situ adsorption magnet 1105 is coaxially connected to the groove depth control rod 1104, and it is magnetically attracted to the magnet ring 1106 corresponding to the position of the groove depth control rod 1104 on the mounting substrate 104. When the groove line cutting disc 3 does not rotate and cut in the initial state, the in-situ adsorption magnet 1105 on the groove depth control rod 1104 is adsorbed and fixed on the magnet ring 1106 on the mounting substrate 104 to achieve the initial positioning of the roller 1101; and

[0059] Groove depth control disc 1107 is threadedly engaged with the groove depth control rod 1104 and can move along the length direction of the groove depth control rod 1104. The distance between the groove depth control disc 1107 and the bottom of the mounting substrate 104 is the depth of the groove to be cut; by adjusting the distance between the groove depth control disc 1107 and the mounting substrate 104, with the measuring scale 1103 as a reference during the grooving process, when the present invention is used to cut a slit against the wall until the groove depth control disc 1107 abuts against the mounting substrate 104, the distance that the groove depth control disc 1107 moves at this time is the depth that the groove line cutting disc 3 enters the wall, thereby realizing the precise control of the wall grooving depth and greatly increasing the efficiency of the grooving operation.

[0060] Furthermore, a receiving cavity 1108 coaxial with the groove depth control rod 1104 is provided at the bottom of the mounting substrate 104, and an elastic element 1109 sleeved outside the groove depth control rod 1104 is connected and arranged in the receiving cavity 1108; when using the groove line cutting disc 3 to advance deep into the wall to start cutting and grooving, when the groove depth control disc 1107 gradually approaches the mounting substrate 104, the groove depth control disc 1107 gradually presses the elastic element 1109 to make it contract into the receiving cavity 1108 until the elastic element 1109 completely enters the receiving cavity 1108, and at this time the groove depth control disc 1107 just fits against the mounting substrate 104.

[0061] Furthermore, an auxiliary cutting disc 105 is provided inside the protective housing 101. The auxiliary cutting disc 105 is perpendicular to the groove line cutting disc 3. The auxiliary cutting disc 105 is installed in the motor bracket 106 and driven by an auxiliary motor 107 on the motor bracket 106; the top of the protective housing 101 is installed with a driver 109 through a U-shaped seat 108. The output end of the driver 109 is connected with a push rod 110. The telescopic movement of the push rod 110 is realized through the driver 109. One end of the push rod 110 is connected with a reciprocating push rod 111 that is slidably matched with the protective housing 101. The reciprocating push rod 111 is connected to the motor bracket 106, and the reciprocating movement of the auxiliary cutting disc 105 of the protective housing 101 is realized through the telescopic movement of the push rod 110.

[0062] Furthermore, a cutting controller 112 is installed at the top of the protective housing 101. The grooving motor 102, the auxiliary motor 107, and the driver 109 are all electrically connected and controlled through the cutting controller 112. During the process of straight-line movement and cutting of the grooved wire cutting disc 3 for grooving, the auxiliary motor 107 is controlled by the cutting controller 112 to operate at intervals. Then, the auxiliary cutting disc 105 is used to cut the cement between the two cut slits again, so that the cement area between the two slits cut by the grooved wire cutting disc 3 is divided into multiple small-sized cement blocks, which facilitates the subsequent knocking and removal of the cement between the two slits. This not only greatly improves the grooving efficiency but also greatly reduces the working intensity of the grooving operators.
