Description

Technical Field

[0001] This utility model relates to the field of lens edging machine technology, specifically to a rotatable head transport and fixing protection device for an eyeglass lens edging machine. Background Technology

[0002] The spectacle lens edging machine is one of the core pieces of equipment in modern eyewear manufacturing. The fixed transport structure of its machine head is crucial to the precision, stability, and service life of the equipment.

[0003] Currently, the common lens edging machine head fixing structures on the market are mainly divided into two types: integrated and independent. However, both of these structures are easily lost, affecting the reliability, maintenance convenience and reusability of the equipment.

[0004] Integrated fixing structure: This structure typically places the fixing point near the rotation axis of the machine head. This area experiences a short lever arm and concentrated stress during the grinding process, causing the fixing point and nearby structures to be under high load during transportation. This makes them highly susceptible to deformation, cracking, or even breakage, severely affecting the core accuracy and lifespan of the equipment.

[0005] When a machine needs to be returned to the factory for repair, this fixing structure usually needs to be disassembled. Due to its high integration and special structure, the small, specialized parts are very easy to lose after disassembly. More importantly, this fixing structure is often not provided as a standard spare part, and the lack of special fixing parts for protective packaging during return for repair makes the risk of collision and vibration damage to the machine head during transportation extremely high due to the lack of effective fixation.

[0006] Independent mounting structure: An independent mounting structure is usually composed of multiple independent parts. During repeated disassembly, transportation, and installation, these parts are very easy to scatter or be lost. Once a key part is lost, the entire mounting structure fails, making it impossible to effectively secure the machine head when the equipment needs to be moved or maintained again, seriously affecting the mobility of the equipment and the convenience of subsequent use. Summary of the Invention

[0007] The purpose of this invention is to address the problem that the fixing and protection device of the edging machine is easily lost in the prior art, and to provide a rotatable machine head transportation fixing and protection device for an eyeglass lens edging machine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a rotatable head transport and fixing protection device for an eyeglass lens edging machine, comprising:

[0009] The fixed body is provided with fixing holes and a machine head contact surface;

[0010] Fixing bolts: Fixing bolts pass through fixing holes to connect the fixing body to the machine head and equipment housing.

[0011] Furthermore, the fixing body is formed by bending sheet metal.

[0012] Furthermore, both ends of the fixing body are provided with fixing holes.

[0013] Furthermore, the fixing hole is oblong.

[0014] Furthermore, the shape of the contact surface of the machine head matches the shape of the machine head.

[0015] Furthermore, the end of the fixing bolt triggers a protective switch located inside the edge grinding machine.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are as follows: it provides a dedicated, reliable and easy-to-install fixing point, which can firmly lock the machine head to the equipment shell or a specific position when the machine head is disassembled and returned to the factory for maintenance or the equipment is moved as a whole.

[0017] It effectively prevents the head from shaking, vibrating and colliding due to lack of restraint in the transport box or during equipment handling, protecting precision bearings, transmission components and optical elements.

[0018] This avoids the embarrassing situation where individual parts can be scattered and lost, making them impossible to secure. Attached Figure Description

[0023] See Figure 1-2 As shown, the technical solution adopted in this specific embodiment is: a rotatable head transport and fixing protection device for an eyeglass lens edging machine, which includes:

[0024] The fixing body 1 is formed by bending sheet metal. Both ends of the fixing body 1 are provided with oblong fixing holes 11. The fixing body 1 is also provided with a machine head contact surface 12 whose shape matches the shape of the machine head 3.

[0025] The fixing bolt 2 passes through the fixing hole 11 to connect the fixing body 1 to the machine head 3 and the equipment housing 4, and the end of the fixing bolt 2 touches the protection switch located inside the edge grinding machine (the protection switch is a conventional technical means in this field, so it will not be described in detail here).

[0026] The working principle of this utility model:

[0027] Fixed transport status (safe transport and storage)

[0028] Preparation: When the edge grinding machine needs to be transported or stored for a long time, the operator moves the machine head 3 to a safe angle position specified by the equipment manufacturer.

[0029] Mounting fasteners:

[0030] Place the fixing body 1 in a predetermined position between the machine head 3 and the equipment housing 4 (usually a frame or fixing base). Ensure that the machine head contact surface 12 of the fixing body 1 fits tightly against the shape of the machine head 3.

[0031] Two fixing bolts 2 are passed through the elongated fixing holes 11 at both ends of the fixing body 1.

[0032] Screw the bolts into the corresponding threaded holes on the machine head 3 and the equipment housing 4, and tighten the fixing bolts 2 securely.

[0033] At this time: the fixed body 1 is rigidly connected between the machine head 3 and the equipment casing 4.

[0034] The machine head 3 is firmly locked to the equipment housing 4 by the fixing body 1 and bolts, which effectively prevents the machine head 3 from moving, shaking or rotating due to vibration or impact during transportation or handling, and avoids the risk of collision damage.

[0035] Electrical protection trigger: When the fixing bolt 2 is fully tightened, its end will activate a pre-set protection switch (usually a limit switch or micro switch) inside the grinding machine. Once triggered, this switch will cut off the power to the moving motor (or other related moving parts) of the machine head 3. This means:

[0036] In the fixed state, any misoperation will prevent the machine head 3 from moving, thus preventing mechanical damage caused by forcibly starting the machine in the fixed state and providing clear hardware interlock safety protection.

[0037] Use the avoidance mode (normal operation)

[0038] When the edge grinding machine needs to be put into normal production and processing, it must first be released from its transport and fixed state.

[0039] Release from fixation and rotation:

[0040] Remove the fixing bolts 2 that connect the fixing body 1, so that the fixing body 1 is no longer tightly clamped between the machine head 3 and the outer casing.

[0041] Rotate the fixed body 1 180 degrees around the bolt axis (or the designed pivot).

[0042] Re-tighten (conceal):

[0043] The rotated fixed body 1 is pushed against the equipment housing 4 (at this time it is in a position that does not interfere with the normal operation and movement of the machine head 3).

[0044] Retighten fixing bolt 2. At this point:

[0045] The main body 1 is fixed to the outer casing 4 of the equipment, but its main body is parallel and close to the frame, thus achieving "concealment".

[0046] The fixed body 1 is no longer connected to the machine head 3, nor does it obstruct any working movement range of the machine head 3.

[0047] With the head 3 fully released, it can freely rotate and move as required for edge grinding.

[0048] Electrical protection deactivation: When the fixing bolt 2 rotates with the fixing body 1 and is tightened back into the "hidden" position, its end leaves the trigger position of the protection switch. The protection switch resets, restoring power supply to the moving motor of the machine head 3, and the equipment can be started and operated normally.

[0049] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
