Description

Technical Field

[0001] This invention relates to a surface grooving device for BM interlocking blocks. Background Technology

[0002] Interlocking blocks, also known as plaster-free interlocking blocks or hollow bricks, are a type of building material made from poured concrete and machine-pressed. BM lightweight aggregate interlocking blocks are small hollow interlocking blocks with tenons and mortises, formed from lightweight aggregate concrete through vibration, pressing, and steam curing. They are used for building non-load-bearing walls.

[0003] When processing interlocking blocks, it is necessary to groove their surfaces to facilitate their installation with the tenon joints on the surface of another interlocking block. However, in actual production, there are various types of interlocking blocks with different tenon positions and sizes, and the corresponding groove positions and sizes are also different. Existing grooving devices can only cut grooves with fixed positions and sizes, and cannot cut grooves of different heights and widths for different interlocking blocks as needed, causing great inconvenience. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a surface grooving device for BM interlocking blocks, which can accurately groove according to the shape and position of the tenon on the actual interlocking block.

[0005] To solve the above-mentioned technical problems, the present invention provides a surface grooving device for BM interlocking blocks, including a horizontal base, several legs on the lower side of the base, a hole penetrating the base vertically in the middle of the base, a horizontally arranged slide rail with a longitudinal direction in the hole, a horizontally arranged first mounting plate on the slide rail, the first mounting plate slidingly engaging with the slide rail, a horizontally arranged first cylinder embedded in the base, the piston rod of the first cylinder extending into the hole, the piston rod having a longitudinal direction in the length direction, the end of the first cylinder piston rod away from the cylinder barrel being connected to the first mounting plate, the first mounting plate having a vertically arranged clamp for clamping BM interlocking blocks, several vertically arranged support plates on the upper side of the base, a horizontally arranged second mounting plate on the support plates, a vertically arranged second cylinder on the second mounting plate, the piston rod of the second cylinder extending vertically downward, the end of the second cylinder piston rod away from the cylinder barrel having a clamp. A horizontally arranged third mounting plate has vertically downward-extending limiting plates at both its left and right ends, with the length direction of the limiting plates being front-to-back. A horizontally arranged crossbar with a length direction of left-to-right is located between the two limiting plates. Two sliders are spaced apart on the crossbar and slide in contact with the crossbar. A horizontally arranged fourth mounting plate is connected to the lower side of the two sliders. A spring is circumferentially fitted between the left-side limiting plate and the left-side slider at the position of the crossbar. The two ends of the spring are connected to the left-side limiting plate and the left-side slider, respectively. A vertically downward-extending guide plate is located on the left side of the fourth mounting plate, with a length direction of front-to-back. A guide slope is located near the lower end of the right side of the guide plate. A vertically arranged fifth mounting plate is located on the right side of the fourth mounting plate, corresponding to the guide plate, with a length direction of front-to-back. A horizontally arranged motor is mounted on the fifth mounting plate, with the motor output shaft extending horizontally to the left and equipped with a processing head.

[0006] For the sake of simplicity, the surface grooving device for BM interlocking blocks described in this invention will be referred to as "this device" in the following description.

[0007] The method of using this device is as follows: First, fix the interlocking block to be slotted using a clamp, so that the tenon of the interlocking block is positioned to the left (corresponding to the guide plate), and the processing head is positioned opposite the right side of the interlocking block. Adjust the front-to-back position of the interlocking block using the first cylinder, then start the motor and control the second cylinder to make the motor move downward. When the guide plate moves downward and touches the tenon, the fourth mounting plate will shift to the left under the action of the guide slope. At this time, the spring is compressed, and the processing head performs a cutting operation under the drive of the fifth mounting plate. After completing a longitudinal cut, control the second cylinder to make the third mounting plate move upward as a whole. When the guide plate leaves the tenon, the fourth mounting plate moves to the right and resets under the action of the spring, and the processing head also exits the interlocking block. At this time, the cutting of a longitudinal groove is completed. If the groove width is wide or there are multiple grooves, the first cylinder can be controlled to move a certain distance and the above operation can be repeated.

[0008] Advantages of this device: This device can accurately slot according to the shape and position of the tenon on the actual interlocking block, and can be applied to all models and sizes of interlocking blocks. It is multi-functional, simple in structure and easy to operate.

[0009] To achieve better performance from this device, the preferred solution is as follows:

[0010] Preferably, a receiving drawer matching the hole is provided at the lower side of the base.

[0011] The receiving drawer makes it easy to collect the waste generated during cutting, and the drawer design also makes it easier to clean up the waste.

[0012] Preferably, a damper is provided between the limiting plate on the left and the slider on the left.

[0013] Dampers prevent damage to the machine from excessive instantaneous force when the spring returns to its original position, and they also make the operation smoother. Attached Figure Description
