Description

Technical Field

[0001] This utility model relates to the field of positioning fixtures for heating devices, and in particular to an adjustable positioning fixture for heating devices. Background Technology

[0002] A heating device is a device that converts electrical energy, thermal energy, or other forms of energy into thermal energy for heating objects or spaces.

[0003] To ensure the normal operation of the heating device, its power usually needs to be tested. The power level is directly related to the energy consumption and heat generation of the heating device. If the actual power exceeds the rated power by too much, it may cause the equipment to operate under overload, causing the heating element to overheat, shortening the service life of the equipment, or even causing safety accidents such as fires. On the other hand, if the power is too low, it may indicate that there is a fault in the equipment, such as damage to the heating element or poor circuit contact. It also needs to be detected and repaired in time to ensure the normal and safe operation of the equipment.

[0004] When conducting power tests on heating devices, it is essential to ensure that the heating device is in a fixed and correct position. This maintains a consistent testing environment and prevents deviations in test results due to device movement. Typically, a positioning fixture is used to fix the heating device in place. Most existing positioning fixtures use quick-clamping clamps for clamping and positioning, but their length is usually not adjustable. This prevents the fixture from being used to clamp and fix workpieces of different sizes and specifications, resulting in insufficient versatility.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an adjustable positioning fixture for a heating device. Through the structural design and cooperation of a first positioning plate, a second positioning plate, and a driving device, both the first and second positioning plates can be selectively locked into corresponding first or second locking holes via fasteners passing through strip holes. This allows for changes in the size of the positioning space, enabling the positioning fixture to be adjusted to clamp and fix workpieces of different sizes and specifications. This provides greater versatility, and the double-limiting structure prevents loosening that could affect accuracy, resulting in better positioning and clamping of the workpiece and reducing the likelihood of workpiece displacement.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An adjustable positioning fixture for a heating device includes a mounting plate and a first positioning plate, a second positioning plate, and a driving device disposed on the mounting plate.

[0009] The mounting plate is provided with a plurality of first locking holes, a plurality of second locking holes, and a first limiting block and a second limiting block for limiting the rear ends of the first positioning plate and the second positioning plate, at least a portion of the first limiting block and the second limiting block are exposed outside the mounting plate.

[0010] The first positioning plate and the second positioning plate are arranged vertically opposite each other to form a positioning space for placing the product to be positioned. Both the first positioning plate and the second positioning plate are provided with strip holes. The strip holes are arranged vertically through a plurality of first locking holes and a plurality of second locking holes. The first positioning plate and the second positioning plate can be selectively locked to the corresponding first locking hole or second locking hole by means of fasteners passing through the strip holes, so as to change the size of the positioning space. The driving device is arranged at the front end of the positioning space.

[0011] As a preferred embodiment, both the first limiting block and the second limiting block include a first limiting edge and a second limiting edge, with the first limiting edge located beside the second limiting edge. The rear end faces of the first positioning plate and the second positioning plate are at least partially constrained by the first limiting edge. The second limiting edge is used to limit the external movement of the product within the positioning space.

[0012] As a preferred embodiment, the mounting plate is further provided with multiple sets of first screw holes, and the first positioning plate and the second positioning plate are provided with second screw holes. The first positioning plate and the second positioning plate are locked to the mounting plate by screws passing through the first screw holes and the second screw holes respectively, thereby preventing the positioning plates from becoming loose and affecting the clamping effect.

[0013] As a preferred embodiment, the back of the mounting plate is provided with an upper transverse groove and a lower transverse groove for mounting and positioning with the machine tool. The machine tool has a slide rail mounting surface, which is provided with an upper transverse protrusion and a lower transverse protrusion. The mounting plate is placed on the machine tool, and the upper transverse groove and the lower transverse groove are engaged and fixed on the upper transverse protrusion and the lower transverse protrusion, so that the installation is stable and prevents loosening during subsequent testing, which would affect the accuracy of the test.

[0014] As a preferred embodiment, the mounting plate is further provided with a first mounting hole, and the machine base is provided with a second mounting hole corresponding to the first mounting hole. The mounting plate is secured to the machine base by screws passing through the first mounting hole and the second mounting hole respectively.

[0015] As a preferred embodiment, the driving device is a cylinder.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly relies on the structural design and cooperation of the first positioning plate, the second positioning plate and the driving device. The mounting plate is provided with a plurality of first locking holes and a plurality of second locking holes. The first positioning plate and the second positioning plate can be selectively locked into the corresponding first locking hole or second locking hole by means of fasteners passing through the strip hole. In this way, the size of the positioning space can be changed, so that the positioning fixture can be adjusted to clamp and fix workpieces of different sizes and specifications when in use, and has stronger versatility.

[0017] Secondly, the design of the first limiting block, the second limiting block, and the driving device is important. The limiting block limits the positioning plate, and with the cooperation of the driving device, the front end of the product in the positioning space can be pressed and limited. In this way, the double limiting structure prevents loosening and affects accuracy, making the positioning fixture better for the workpiece and less prone to displacement.
