Description

Technical Field

[0001] This utility model belongs to the field of bone cutting technology, and in particular relates to a stable clamp for bone cutting. Background Technology

[0002] This bone cutting machine is suitable for processing various small and medium-sized animal bones, frozen meat, fish bones, frozen fish, and ice blocks. It is used for cutting small pieces of frozen meat and ribs. It is widely applicable in large-scale centralized food processing plants, slaughterhouses, meat processing plants, and other similar locations.

[0003] Currently, most aggregate cutting machines on the market mainly consist of a housing with a worktable mounted on it, and a cutting device consisting of a saw blade or cutter. When cutting aggregate, the operator holds the aggregate to be processed close to the cutting device, pushes the aggregate during the cutting process, and thus achieves the purpose of cutting the aggregate.

[0004] However, since cow bones are relatively hard, the operator needs to apply a certain pushing force at one end to make a complete cut. However, the application of pushing force can easily lead to improper operation, which can cause injury to the human body from the bone cutting machine and pose a safety hazard. Therefore, it is urgent to design a stable clamp for bone cutting to solve the above problems. Utility Model Content

[0005] This invention provides a structurally sound and stable clamp for bone cutting to address technical problems existing in prior art. This invention can stably clamp the bone to be cut and automatically push it towards the cutting device in the bone cutting machine, eliminating the need for manual cutting by hand and enhancing safety.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A stable clamp for bone cutting includes a pushing drive assembly, a clamping mounting base is installed on the moving end of the pushing drive assembly, a clamping component one is installed on the clamping mounting base for clamping and fixing the aggregate, and a floating support assembly and a clamping component two are installed on the clamping mounting base, the floating support assembly and the clamping component two are respectively distributed on both sides of the clamping component one; the clamping component one includes a swinging upper clamping jaw and a fixed lower clamping jaw that are distributed vertically and pivotally connected, and V-shaped grooves are opened on the opposite surfaces of the swinging upper clamping jaw and the fixed lower clamping jaw, and a clamping cylinder is pivotally connected between the swinging upper clamping jaw and the fixed lower clamping jaw; the clamping component two includes a clamping cylinder, a clamping stand is installed on the two moving ends of the clamping cylinder, and a plurality of clamping roller mechanisms are elastically connected to each clamping stand, the plurality of clamping roller mechanisms are arranged opposite each other in pairs.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a stable clamp for bone cutting. Through the first clamping component, stable clamping of the aggregate can be performed in the vertical direction. Through the second clamping component, the aggregate can be clamped in the left-right direction. Given that the aggregate is not a standard columnar structure and the size of the aggregate to be cut varies, the clamping roller mechanism is elastically connected to the corresponding gripper stand. This ensures that during clamping operations, the relatively arranged clamping roller mechanism can clamp aggregates of different sizes and volumes, and can adapt to the curvature of the aggregate in the length direction, thus ensuring stable clamping. The floating support component provides stable support for the aggregate to be cut, ensuring clamping stability during the pushing process and improving the cutting quality of the aggregate cutting operation. The pusher drive component automatically pushes the aggregate into the cutting device of the aggregate cutting machine, eliminating the need for operators to manually cut the aggregate, thus enhancing safety.

[0022] like Figure 2 As shown, the clamping assembly 4 includes a swinging upper clamping jaw 4-3 and a fixed lower clamping jaw 4-4 that are pivotally connected and arranged vertically. V-grooves are formed on the opposing surfaces of both the swinging upper clamping jaw 4-3 and the fixed lower clamping jaw 4-4. The bottom surfaces of the V-grooves on both the swinging upper clamping jaw 4-3 and the fixed lower clamping jaw 4-4 are serrated. The clamping assembly 4 also includes a clamping cylinder 4-1 pivotally connected between the swinging upper clamping jaw 4-3 and the fixed lower clamping jaw 4-4; and a lower clamping jaw support 4-5 mounted on the clamping mounting base 2 for mounting the fixed lower clamping jaw 4-4. Two opposing cylinder mounting arms 4-2 are fixedly connected to the fixed lower clamping jaw 4-4. The cylinder of the clamping cylinder 4-1 is pivotally connected to the cylinder mounting arms 4-2 via a pin.

[0023] like Figure 3 As shown, the clamping assembly 2 5 includes a gripper cylinder 5-1, with gripper stands 5-2 installed at the two moving ends of the gripper cylinder 5-1. Several gripping roller mechanisms 5-3 are elastically connected to each gripper stand 5-2, and the gripping roller mechanisms 5-3 are arranged opposite each other in pairs. The aforementioned gripping roller mechanism 5-3 includes a buffer guide sleeve 5-3-2 installed on the gripper stand 5-2, a buffer guide rod 5-3-1 slidably connected to the buffer guide sleeve 5-3-2, a roller seat 5-3-4 installed at the inner end of the buffer guide rod 5-3-1, a gripping roller 5-3-5 connected to the roller seat 5-3-4, and a buffer spring 5-3-3 sleeved on the buffer guide rod 5-3-1 and located between the roller seat 5-3-4 and the gripper stand 5-2. In addition, a plate is installed at the outer end of the buffer guide rod 5-3-1 to block and limit it, so as to prevent the buffer guide rod 5-3-1 from detaching from the buffer guide sleeve 5-3-2 under the elastic force of the buffer spring 5-3-3.

[0024] like Figure 3As shown, the clamping roller 5-3-5 is rotatably connected to the roller seat 5-3-4 via a shaft and rolling bearing. The clamping roller 5-3-5 has a variable-diameter groove with gradually changing width and depth along its circumferential direction. Several pin holes are circumferentially distributed on the end face of the clamping roller 5-3-5, and arc-shaped holes corresponding to these pin holes are formed on the roller seat 5-3-4. The clamping roller 5-3-5 and the roller seat 5-3-4 are locked together by bolts passing through the corresponding pin holes and arc-shaped holes. This configuration allows for the clamping of aggregates of different sizes and volumes, ensuring stability during the pushing process and improving the cutting quality of the aggregate cutting operation.

[0025] See further Figure 4 The aforementioned floating support assembly 3 includes a support mounting base 3-1 mounted on the clamping mounting base 2, at least two floating guide sleeves 3-2 mounted on the support mounting base 3-1, a floating guide rod 3-3 slidably connected to each floating guide sleeve 3-2, and a floating spring 3-4 located above the support mounting base 3-1 mounted on each floating guide rod 3-3; it also includes a floating seat plate 3-5 connected to the top of each floating guide rod 3-3, and a support block 3-6 with a V-groove mounted on the floating seat plate 3-5. Additionally, two washers are mounted on the floating guide rods 3-3, located above and below the floating springs 3-4 respectively, and the two washers are in abutting contact with both ends of the floating springs 3-4; a limiting member is installed at the lower end of the floating guide rod 3-3 to limit its movement and prevent it from detaching from the floating guide sleeve 3-2 under the elastic force of the floating spring 3-4.

[0026] See further Figure 5 The aforementioned pusher drive assembly 1 includes a pusher base plate 1-1, on which two parallel linear guide rails 1-2 are fixedly connected.

It also includes a pusher screw 1-5 rotatably connected to the pusher base plate 1-1 and arranged parallel to the linear guide rails 1-2. The movable mounting seat 1-6 is connected to the pusher screw 1-5 via a nut. Furthermore, it includes a pusher motor 1-4 mounted on the pusher base plate 1-1 for driving the pusher screw 1-5 to rotate. Two limiting blocks 1-3 are mounted on the pusher base plate 1-1, located at the two ends of the linear guide rails 1-2 respectively. Rubber anti-collision blocks are mounted on the sides of each limiting block 1-3.

[0027] Working principle:

[0028] In the initial state, the piston rod of the clamping cylinder 4-1 is in a retracted state, facilitating the placement of the aggregate to be cut into the V-groove on the fixed lower jaw 4-4. Simultaneously, it ensures that the rear section of the aggregate rests on the support block 3-6 in the floating support assembly 3, while the front section is positioned between several opposing clamping roller mechanisms 5-3. Then, the clamping cylinder 4-1 and the jaw cylinder 5-1 are activated, causing the swinging upper jaw 4-3 and the fixed lower jaw 4-4 to clamp the aggregate vertically, while the opposing clamping roller mechanisms 5-3 clamp the aggregate horizontally. Since the aggregate is not a standard columnar structure, the clamping rollers 5-3-5 can be rotated according to the aggregate's diameter, allowing the grooves of the clamping rollers 5-3-5 to... Rotate to a suitable position for clamping the aggregate. In addition, since the clamping roller mechanism 5-3 is elastically connected to the corresponding gripper stand 5-2, it can ensure that when the gripper cylinder 5-1 is started, the relatively arranged clamping roller mechanisms 5-3 can clamp aggregates of different sizes and volumes, and can adapt to the curvature of the aggregate in the length direction. During the above clamping operation, the floating support component 3 can provide good support for the rear section of the aggregate to be cut, and adapt to the diameter of the aggregate and the curvature in the length direction. After the above clamping operation is completed, start the pusher motor 1-4 in the pusher drive component 1, drive the pusher screw 1-5 to rotate, and then drive the movable mounting seat 1-6 to move toward the bone cutting device, so as to achieve the purpose of pushing the material toward the bone cutting device.
