Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tooling for roll grinders, and in particular relates to a clamping device used for grinding multiple disc shear blades on a roll grinder. Background Art
[0002] On the production line of titanium plate and strip finishing process, the main production equipment of the finishing process, such as the trimming and rewinding unit and the longitudinal and transverse combined shearing unit, are equipped with circular scissors. The titanium plates and strips must be trimmed and stripped during the production process, and the circular scissors used need to be replaced and ground regularly.
[0003] At present, the external cylindrical grinding method of the disc scissors blades is to repeatedly remove the fixture for installing the blades and then fix the disc scissors blades one by one, fix the disc scissors blades on the fixture of the roll grinder and then perform external cylindrical grinding one by one, which is very time-consuming and has low grinding efficiency. Utility Model Content
[0004] The utility model aims at the above-mentioned problems, makes up for the deficiencies of the prior art, and provides a clamping device for grinding multiple disc shear blades on a roll grinder; the utility model can simultaneously group multiple disc shear blades and install them at one time to grind multiple blades in the same group at the same time, thus saving grinding time and improving grinding efficiency.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions.
[0006] The utility model provides a clamping device for grinding multiple disc shear blades on a roll grinder, comprising a core shaft, a shoulder is provided on one side of the middle portion of the core shaft, a locking thread is provided on the other side of the middle portion, a spacer is detachably provided on the core shaft at a certain distance between the shoulder and the locking thread, and a mounting portion is provided between two adjacent spacers, the mounting portion is used for simultaneously sleeved a plurality of disc shear blades of the same batch, and a locking nut is matched and connected at the locking thread.
[0007] Furthermore, the core shaft is provided with a guide key that cooperates with the guide groove of the disc scissor blade, and the spacer is provided with a groove that matches the guide key.
[0008] Furthermore, a threaded protective sleeve made of nylon material and having threads is detachably provided outside the locking thread.
[0009] The beneficial effects of the utility model.
[0010] The utility model has a simple structure and can be directly installed on a CNC roller grinder for use. Multiple batches of disc scissor blades can be installed in groups at one time, and disc scissor blades in the same group and batch can be ground simultaneously, which greatly reduces the grinding time and improves the efficiency of grinding the disc scissor blades. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.
[0012] Figure 1 It is a schematic diagram of the structure of the utility model after installation.
[0013] Figure 2 It is a structural schematic diagram of the mandrel of the utility model.
[0014] Markings in the figure: 1 is the core shaft, 2 is the shaft shoulder, 3 is the locking thread, 4 is the spacer, 5 is the mounting part, 6 is the guide key, 7 is the locking nut, 8 is the blade, and 9 is the roll grinder. DETAILED DESCRIPTION
[0015] As shown in the accompanying drawings, this embodiment provides a clamping device for grinding multiple disc shear blades on a roll grinder, including a mandrel 1. The mandrel 1 is designed according to the dimensions allowed by the existing roll grinder 9 to ensure that it complies with the grinding process of the roll grinder 9.
[0016] A shoulder 2 is provided on one side of the middle of the mandrel 1 for limiting the position of the disc scissor blade 8 after installation, and a locking thread 3 is provided on the other side of the middle, and a locking nut 7 is connected to the locking thread 3. In order to avoid damaging the locking thread 3 when installing the disc scissor blade 8, a nylon thread protection sleeve 7 can be put on the locking thread 3 when installing the blade 8. After the blade 8 is installed, the thread protection sleeve is removed, and then the locking nut 7 is screwed on the screw locking thread 3.
[0017] A spacer sleeve 4 is detachably provided on the core shaft 1 at a certain distance between the shaft shoulder 2 and the locking thread 3, and a mounting portion 5 is provided between two adjacent spacers 4. The mounting portion 5 is used for simultaneously mounting a plurality of circular scissor blades 8 of the same batch.
[0018] To facilitate the grinding operation, the size of each spacer 4 is larger than the thickness of the grinding wheel of the grinder. Before using the fixture to grind the blade 8, the blades 8 to be ground are classified into the same diameter according to the batch outer circle size, and the thread protection sleeve 7 is installed before installing the blade 8.
[0019] Then, the classified groups of multiple blades 8 are installed on the core shaft 1 in sequence, and each group is separated by a spacer 4. Each group of blades 8 and the spacer 4 are installed in sequence. The core shaft 1 is provided with a guide key 6 that cooperates with the guide groove of the disc scissor blade 8 to ensure that the blade 8 does not move in the axial direction of the core shaft 1. In order to install the spacer 4, a groove matching the guide key 6 is provided on the spacer 4. Finally, the locking nut 7 is used to lock it, and the blades 8 are installed in groups on the fixture at one time.
[0020] After the blades 8 are installed in groups, they are hoisted onto the roll grinder 9 by a crane. Since the mandrel 1 is designed according to the requirements of the roll grinder 9, the support pads, rotating brackets and soft landing of the roll grinder 9 can be used directly. After installation, the operator of the roll grinder 9 can perform grinding operations.
[0021] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the implementation mode of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
