Description

Technical Field

[0001] This utility model relates to the field of wood testing technology, and in particular to a wood testing device. Background Technology

[0002] Wood processing refers to the production process of shaping, surface treating, and assembling logs or boards using mechanical or manual methods such as sawing, planing, drilling, and sanding to create furniture, building components, handicrafts, and other wood products. During processing, it is necessary to control the moisture content, grain direction, and processing precision of the wood to ensure the quality of the finished product. After production, rigorous testing is required, including tests for dimensional accuracy, surface finish, structural strength, and environmental indicators (such as formaldehyde emissions), to ensure that the products meet industry standards and customer requirements.

[0003] Existing wood strength testing methods typically only have a single testing or pressing function, with relatively fixed clamping methods that cannot flexibly adapt to wood of different sizes or shapes, resulting in low processing efficiency. At the same time, wood chips and other impurities generated during testing or pressing are easily left inside the device, making it inconvenient to clean in time and easily accumulating and affecting the next use. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a wood testing device that solves the problem that existing wood strength testing devices typically only have a single testing or pressing function, with a relatively fixed clamping method that cannot flexibly adapt to wood of different sizes or shapes, resulting in low processing efficiency. Furthermore, wood chips and other impurities generated during the testing or pressing process are easily left inside the device, making them inconvenient to clean in a timely manner and prone to accumulating and affecting future use.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solution adopted by this utility model is as follows:

[0008] A wood testing device includes a base plate, a support rod fixedly connected to the base plate, a processing table fixedly connected to the support rod, a pressure assembly installed on the processing table, a limit device installed on the processing table, and a moving device fixedly connected below the limit device.

[0009] The limiting device includes two nut plates and a housing. The two nut plates are internally threaded with the same threaded rod. The two nut plates are respectively mounted with a drive plate via a connecting shaft. The drive plate is movably connected inside the housing. The two drive plates are fitted with the same frame. The upper and lower surfaces of the frame are each provided with two sliding grooves. Four clamping plates are slidably connected inside the frame. Each clamping plate is equipped with two sliding rods at its upper and lower ends. The sliding rods are slidably connected within the sliding grooves.

[0010] The nut plate overlaps the upper surface of the processing table, the housing is fixedly connected to the upper surface of the processing table, the processing table has a through hole, and the housing, frame and drive disk all have through holes of the same size.

[0011] The limiting device also includes a support column and two inclined grooves. The diameter of the cross-section of the support column is larger than the inner diameter of the through hole in the processing table, and it is engaged on the lower surface of the through hole.

[0012] The two inclined slots are symmetrically opened in the drive disk, and the slide rod is slidably connected in the inclined slots.

[0013] The moving device includes a long plate and a rectangular plate. The long plate is fixedly connected to the upper surface of the base plate. A sliding plate is slidably connected to the outside of the long plate. Several limiting grooves are opened in the long plate. A push rod is installed in the sliding plate.

[0016] (III) Beneficial Effects

[0017] The beneficial effects of this utility model are as follows: When the user rotates the turntable, it drives the threaded rod to rotate, and the nut plate moves in the opposite direction under the action of the thread, thereby driving the two drive discs to rotate in opposite directions. Each drive disc has a symmetrically opened inclined groove, and a sliding rod is provided in the inclined groove. The sliding rod is connected to the clamping plate slidably installed in the upper and lower inclined grooves. When the drive disc rotates, the inclined groove guides the sliding rod to slide along the inclined trajectory, driving the clamping plate to move inward. The four clamping plates move closer together synchronously under the guidance of the frame structure, effectively clamping the wood placed in the central area. This structure is not only suitable for wooden boards and sticks of different widths and thicknesses, but also allows for fine adjustment of the clamping force through the turntable, improving clamping stability and adaptability. At the same time, the moving device set at the bottom cooperates with the sliding plate through the long plate. The internal limit and release structure of the push rod, long rod, and locking block allows the sliding plate to drive the upper support column away from the through hole of the processing table at a specific time, thereby releasing the through hole area and facilitating the free fall of wood chips. After further pushing the sliding plate, the wood chips that have fallen to the bottom can be guided into the receiving container for cleaning, improving the efficiency of use and the cleanliness of the environment.

[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 4As shown, a wood testing device of this utility model includes a base plate 1, a support rod 2 fixedly connected to the base plate 1, a processing table 3 fixedly connected to the support rod 2, a pressure assembly 4 installed on the processing table 3, a limiting device 5 installed on the processing table 3, and a moving device 6 fixedly connected below the limiting device 5.

[0026] The limiting device 5 includes two nut plates 501 and a housing 504. The two nut plates 501 are internally threaded with the same threaded rod 502. The two nut plates 501 are respectively mounted with drive discs 505 through connecting shafts. The drive discs 505 are movably connected in the housing 504. The two drive discs 505 are fitted with the same frame 506. The upper and lower surfaces of the frame 506 are each provided with two sliding grooves 507. Four clamping plates 508 are slidably connected in the frame 506. Two sliding rods 509 are installed on the upper and lower surfaces of the clamping plates 508. The sliding rods 509 are slidably connected in the sliding grooves 507. In actual implementation, when the user rotates the turntable 503, it drives the threaded rod 502 to rotate, and the nut plate 501 moves in the opposite direction under the action of the thread, thereby driving the two drive discs 505 to rotate in opposite directions. Each drive disc 505 has a symmetrically opened inclined groove 510, and a slide rod 509 is provided in the inclined groove 510. The slide rod 509 is connected to the clamping plate 508 slidably installed in the upper and lower sliding grooves 507. When the drive disc 505 rotates, the inclined groove 510 guides the slide rod 509 to slide along the inclined trajectory, driving the clamping plate 508 to move inward. The four clamping plates 508 move closer together synchronously under the structural guidance of the frame 506, effectively clamping the wood placed in the central area. This structure is not only suitable for wooden boards and sticks of different widths and thicknesses, but also allows for fine adjustment of the clamping force through the turntable 503, improving clamping stability and adaptability.

[0027] Optionally, the nut plate 501 overlaps the upper surface of the processing table 3, and the housing 504 is fixedly connected to the upper surface of the processing table 3. The processing table 3 has a through hole, and the housing 504, frame 506, and drive disc 505 all have through holes of the same size. In actual implementation, the threaded rod 502 passes through and is threadedly connected to the two oppositely arranged nut plates 501. During operation, simply rotating the threaded rod 502 allows the two nut plates 501 to move synchronously in opposite directions via the threaded transmission principle. This coordination enables equal adjustment of the clamping range, ensuring the synchronous rotation of the drive discs 505 on both sides, which helps the subsequent clamping plate 508 to form a balanced clamping force, suitable for positioning timber of different sizes.

[0028] Optionally, the limiting device 5 also includes a support column 511 and two inclined grooves 510. The diameter of the cross-section of the support column 511 is larger than the inner diameter of the through hole in the processing table 3, and it is engaged on the lower surface of the through hole. The two inclined grooves 510 are symmetrically opened in the drive disk 505, and the slide rod 509 is slidably connected in the inclined grooves 510. In actual implementation, the drive disk 505 is provided with an inclined groove 510 structure. The slide rod 509 is located in the inclined groove 510 and is driven by the rotation of the drive disk 505 to move along the inclined trajectory. Since the inclined groove 510 has an inclination angle, when the drive disk 505 rotates, the rotational motion can be converted into the linear sliding of the slide rod 509, thereby driving the clamping plate 508 to perform clamping or loosening actions. This matching structure simplifies the power conversion path and improves the response sensitivity and action stability of the clamping mechanism.

[0029] Optionally, the moving device 6 includes a long plate 601 and a rectangular plate 605. The long plate 601 is fixedly connected to the upper surface of the base plate 1. A sliding plate 602 is slidably connected to the outside of the long plate 601. Several limiting grooves 603 are opened in the long plate 601. A push rod 604 is installed in the sliding plate 602. A long rod 607 is installed in the push rod 604. A through groove 606 is opened in the rectangular plate 605. The long rod 607 is set in the through groove 606. A locking block 608 is fixedly connected to the outside of the rectangular plate 605 and is locked in the corresponding limiting groove 603. A sliding connection is formed between the push rod 604 and the sliding plate 602. A sliding connection is formed between the locking block 608 and the sliding plate 602. A support column 511 is fixedly connected to the upper surface of the sliding plate 602. A groove is opened on the upper surface of the sliding plate 602 to facilitate pulling. In actual implementation, the locking block 608 is fixed to the outside of the rectangular plate 605 and is used to insert into the preset limiting groove 603 of the long plate 601 to realize the limiting and release of the slide plate 602 at a specific position. When it is necessary to move the slide plate 602 for sawdust cleaning, the long rod 607 is moved by pushing the push rod 604, which in turn causes the locking block 608 to disengage from the limiting groove 603. This structure is easy to operate and has a quick locking / unlocking function, which facilitates the control of the slide plate 602 and improves the flexibility of use. The moving device 6 cooperates with the slide plate 602 through the long plate 601. The limiting and release structure of the push rod 604, the long rod 607, and the locking block 608 inside allows the slide plate 602 to move the upper support column 511 away from the through hole of the processing table 3 at a specific time, thereby releasing the through hole area and facilitating the free fall of sawdust. After further pushing the slide plate 602, the sawdust falling to the bottom can be guided into the receiving container to complete the cleaning, improving the efficiency of use and the cleanliness of the environment.
